attachments and flying particles.
INCORRECT USE OFTHE SURFACE GRINDER CAN
RESULT IN PROPERTY DAMAGE, PERSONAL
INJURY OR EVEN DEATH. TO REDUCE THIS
POSSIBILITY, GIVE COMPLETE AND UNDIVIDED
ATTENTION TO THE JOB AT HAND AND FOLLOW
THESE SAFETY PRECAUTIONS:
5) Operators must be in adequate physical condition,
mental health and not under the influence of any
substance (drugs, alcohol, etc.) which might impair
vision, dexterity or judgment. Working with the
SURFACE GRINDER is strenuous. If you have any
condition that might be aggravated by strenuous work,
check with your doctor BEFORE operating the
SURFACE GRINDER. Guide against the possibility of
back related injuries. Always lift the SURFACE
GRINDER with leg muscles and not with the back.
PREPARATION
1) This SURFACE GRINDER is specialized type of
powered equipment, designed for a specific job function
and requires adequate and thorough instruction
BEFORE it is operated. The size, power, complexity
and operating characteristics of this type of powered
equipment would dictate that each operator must receive
adequate, professional instruction regarding the proper
operation of this SURFACE GRINDER before being
allowed to utilize it. BEFORE attempting to utilize this
SURFACE GRINDER, read this Operator’s Manual and
the material supplied by the motor manufacturer to
familiarize each operator with its correct operating
procedures. Avoid the urge not to take the necessary
time to read this Operator’s Manual before operating
the SURFACE GRINDER. DO NOT OPERATE THE
SURFACE GRINDER UNTIL EACH OPERATOR
COMPLETELY COMPREHENDSTHE CONTENTS OF
THIS MANUAL.
6) Prolonged use of the SURFACE GRINDER (or other,
similar machines) exposes the operator to vibrations
which may produce Whitefinger Disease (Raynaud’s
Phenomenon). This phenomenon reduces the hand’s
ability to feel and regulate temperature, produces
numbness and burning sensations and may cause nerve
and circulation damage and tissue necrosis. Anti-
vibration systems do not guarantee that you will not
sustainWhitefinger Disease.Therefore, continuous and
regular users should closely monitor the condition of
their hands and fingers. After each period of use,

exercise to restore normal blood circulation. If any of
the symptoms appear, seek medical advice immediately.
electrical cables, gas lines and other hazardous items
can result in electrocution and/or an explosion.
10) Know how the controls operate. Know how to stop the
electric motor quickly in an emergency. Always start
the electric motor according to the instructions as
outlined in this manual to minimize the possibility of
unexpected contact with the work surface. Unexpected
contact with the work surface can cause loss of
machine control, and the possibility of property damage
and/or personal injury.
7) Clothing must be sturdy and snug fitting, but allow
complete freedom of movement. Never wear loose fitting
jackets, scarves, neckties, jewelry, flared or cuffed
pants or anything that could become caught on controls
or moving parts. Wear long pants to protect your legs.
Protect your hands with heavy duty, non-slip gloves to
improve your grip.Good footing is most important when
operating the SURFACE GRINDER.
11) Ground the electrically powered SURFACE GRINDER
motor securely.Determine that any“grounding”wire and/
or device is, in fact, properly grounding the motor.Failure
to properly ground the motor may cause an electrical
shock and/or electrocution, resulting in property
damage and personal, injury including death. Electrical
wiring and all connections should be performed by a
qualified electrician. The electric motor is designed to
operate from a 115 AC power source.
Wear sturdy boots with non-slip soles. Steel-toed safety
shoes are highly recommended. Never wear tennis
shoes or other, similar type shoes which afford little or
no protection. Wear an approved safety hard hat to
protect the operator’(s’) head(s) where there is a danger
of head injuries. Noise, generated by the SURFACE
GRINDER and the actual process itself, can damage
your hearing.Wear approved sound barriers (ear plugs
or ear mufflers) to protect your hearing. Continuous and
regular operators should have their hearing checked
regularly.
12) When operating the SURFACE GRINDERs on a surface
containing water or other electrically conducting liquid,
special precautions must be taken to minimize the
possibility of operator electrocution. Once such
precaution is to wire and operate the electric motor from
a clean, 20 Ampere, 115 Volt AC power source in
conjunction with a ground fault circuit interrupter (GFCI).
A GFCI is a safety device that disconnects power from
a circuit to a load when a potentially dangerous condition
occurs. The GFCI opens the circuit when the fault
current flow from a power line to a ground exceeds the
safe limit for humans.
8) Visually inspect the SURFACE GRINDER, components,
tools and accessories for damaged or worn parts.
BEFORE each use:
a) Disconnect the power source cable.
b) Clean and remove all accumulated foreign matter
from the wheels and determine that each rotates
freely.
c) Clean and remove all accumulated foreign matter
from inside the mainframe area.
The GFCI protects against harmful electrical shock to
a person caused by contact with a defective electrical
product. A GFCI differs from a fuse or circuit breaker.A
fuse or circuit breaker opens the circuit when the total
current flow in the power line exceeds the safe limit of
the power line. They are designed to protect against
fire caused by overheating of the power line. Use of a
GFCI gives on the job protection from electrical shock
hazards caused by ground faults in commercial,
industrial and residential applications.They are simple
and easy to use:plug a portable GFCI into any suitable,
grounded extension cord and plug the SURFACE
GRINDER into the GFCI for automatic protection
against ground faults.
d) Inspect theV-belt drive for proper tension, wear and
general condition. Replace each component as
necessary.
e) Inspect the multi-accessory disc and gimbal head
assembly for excessive wear and structural
integrity. Replace each component as necessary.
The multi-accessory disc rotating at high speed
during the specific process can be subject to high
wear rates if the installed attachment is not properly
maintained and/or replaced at regular service
intervals.
f) Determine that operator controls work freely, all
safety devices are operative and information decals
are readable.
For specific information, consult current National
Electrical Code® publications and OSHA publications
210-22D (or current revision) for construction sites and
555-3 (or current revision) for use around any area
containing water.
g) Check to see that the SURFACE GRINDER and all
related accessories are in good, mechanical
condition BEFORE utilization.
h) Reconnect the power source cable as applicable.
9) Contact appropriate representatives to determine if/
where electrical cables, gas lines and other hazardous
items are buried under the work surface BEFORE
utilization. The SURFACE GRINDER and related
accessories are not insulated. Contact with buried

low cost, hand held, low horsepower, portable type
machine, it is limited in the number of practical and/or
suitable job applications. A particular job site, actual
surface conditions, job specifications and operator skill/
common sense may dictate that a different type of
machine (with characteristics of higher purchase cost,
being mounted to a carrier vehicle, with greater
horsepower and less mobility), method and/or process
be utilized to properly complete the job with the degree
of efficiency and safety required. Contact the Customer
Service Department for specific information regarding
suitable job applications, job sites surface conditions
and operator experience/skill/common sense
recommendations for this SURFACE GRINDER
BEFORE utilization.There is no charge for this service.
4) Do not operate the SURFACE GRINDER with onlookers
close by. Caution all onlookers to stand clear. The
grinding process can result in flying particles being
emitted at high velocity and striking the operator and/
or onlookers.This can lead to the possibility of property
damage and/or personal injury. Keep all body parts,
loose clothing and foreign objects clear of the rotating
drum and flails.
5) Start the electric motor according to the instructions
as outlined in this manual to minimize the possibility of
unexpected contact with the work surface. Unexpected

ASSEMBLY INSTRUCTIONS/OPERATIONS
1) To contain loose materials within the platform area of
the SURFACE GRINDER as a direct result of a specific
grinding process.This includes materials removed from
the surface as well as any slurry mixture utilized to
help maximize material removal efficiencies.
Assembly
The SFG10E SURFACE GRINDER is shipped from the
factory secured on a specially designed wooden pallet
and protected from external damage by a corrugated carton
or wood crate. If shipped with a corrugated carton, the
SURFACE GRINDER can be secured to the pallet by wood
laths nailed to the pallet body.Remove the carton or crate
immediately upon receipt using suitable tools to remove
the nails.
2) To provide a method for a vacuum system to help
remove airborne dust related materials from within the
skirt assembly. Dust related materials are usually
created as a result of the grinding process. A specific
job application may require the reduction and/or
minimization of airborne dust related materials from the
atmosphere while the SURFACE GRINDER is being
operated. The kit includes a hose and necessary
hardware to connect the skirt assembly to the 3 inch
diameter vacuum attachment fitting located at the rear
of the machine. Use of the kit along with a suitable
vacuum system will not completely remove all airborne
and loose materials directly from the work surface.
REMOVING THE SURFACE GRINDER FROM THE
PALLET
Tools Required:
1 set of pliers.
1 claw hammer or a hammer and an appropriate pry bar.
The SURFACE GRINDER is secured to the pallet with
steel banding. Using the pliers, cut and remove the

Operation
THEORY OF OPERATION
The SFG10E SURFACE GRINDERS operate on the principle
of various multi-accessory attachments being utilized at
rotational speeds to make direct contact with a work
surface.Various types of multi-accessory attachments are
secured to a recess provided in the rotating, aluminum disc
located on the bottom of the machine.The specific type of
multi-accessory attachment utilized during the grinding
process directly affects the type of material removed, the
material removal rate and the resulting flatness and
smoothness of the surface.
The grinding process is directly controlled by these
conditions:
1) The use of a suitable mechanism (multi-accessory
attachment) of proper design and configuration to grind
the work surface and remove material while delivering
acceptable service life.
2) Sufficient static weight supporting the multi- accessory
attachment to allow it to effectively penetrate the work
surface and remove material.
FIGURE 4
3) Adequate horsepower capable of propelling the multi-
accessory attachment against the work surface to
deliver acceptable productivity rates.
The designation system for the grinding stones utilizes a
system similarly utilized for most abrasive products: the
larger the number, the finer the grain structure and usually,
the smoother resulting finish.
Since no two materials are exactly alike, no two work surface
materials can be penetrated and removed by the exact same
method. The nature of the grinding process, along with
operator experience, skill and common sense, would
suggest that efficient and productive material removal is a
matter of trial and error. Combinations of multi-accessory
attachment type, condition, and feed rate are direct factors
that will also determine the overall success of the job
application.
a) The C06 and C10 coarse grade stones are the most
popular utilized stones and result in maximum material
removal rates.They are utilized for general grinding and the
removal of trowel marks, high spots and rough sections on
concrete surfaces.The average service life is approximately
4 to 10 hours.
b)The C24 medium grade stone will result in lower material
removal rates. It is utilized for finer finish grinding of concrete
and rough grinding on terrazzo and other types of stone
floor configurations.The average service life is approximately
6 to 10 hours.
MULTI-ACCESSORY ATTACHMENTS AND APPLICATIONS
While individual multi-accessory attachment design and
configuration may vary, basic operational characteristics
are identical: impact upon a work surface material and
remove a percentage of the material. This common
operational characteristic has led to the development of
the following popular multi-accessory attachments:
c)The C80 fine grade stone will result in still lower material
removal rates. It is utilized for polishing concrete and
medium grinding on terrazzo and other types of stone floor
configurations with a water/slurry mixture only.The average
service life is approximately 8 to 20 hours.
Grinding Stones
Grinding stones are available in a number of grades,
including: C06 extra coarse, C10 coarse, C24 medium, C80
fine and C120 super fine grade. FIGURE 4. All stones
incorporate silicon carbide as the abrasive medium and
employ a clay binder as the matrix material. Vitrified type
stones utilize an oven baking process that produces greater
service life over other manufacturing processes. As the
clay material wears away, it exposes new, sharp, edges of
d)The C120 super fine grade stone will result in the lowest
material removal rates. It is utilized for final polishing on
terrazzo and other types of stone floor configurations with
a water/slurry mixture only. The average service life is
approximately 40 to 75 hours.

configurations can then be utilized for the final finishing

Many flail configurations are available to meet a wide variety
of job applications and surface material specifications. To
give additional perspective to each configuration, a rating
system of 1 to 10 (10 being highest) has been devised.

The pentagonal flail is designed for more aggressive and
rapid removal of a surface in comparison to the beam flail.
The addition of the tungsten carbide inserts contributes to
its long service life and higher production rates.The use of
tungsten carbide is also the main reason for the cost
differential between it and the other flails. The design
configuration yields a rather coarse surface finish and
texture. For many job applications, this finish and texture
will be satisfactory. Some applications may require an
additional smoothing process. If the resulting surface finish
is too coarse to meet specifications, it can be smoothed
with the use of the star or beam flail.

Spacer washers serve the following functions:

1) Reduces the number of flails required to be mounted
on the scarifier block, thus reducing purchase and
operational costs.
2) Arrange the flails in a sequence or pattern that minimize
“blind” or “open” spots. Normally, at least one spacer
washer is inserted between two consecutive flails. A
scarifier block set up with only star, beam or pentagonal
flails will not penetrate the work surface at satisfactory
rates. This configuration will minimize the hammering
or impact action of the flails.
FIGURE 11
1) Inadequate free play exists between the flails/spacer
washers and the scarifier block case. If the flails and
spacer washers do not have complete freedom of
movement, they will not be capable of properly rotating
about the scarifier block bushing.The result is bushing
wear usually confined to two locations that are 180
degrees apart. Variances in flail and spacer washer
thicknesses affect free play when assembled on the
scarifier block.
Variances in material thickness and manufacturing
processes can affect the final thickness of both flails and
spacer washers. Because of this occurrence, trial and error
is important for assembling flails and spacer washer on the
scarifier block. By mixing and matching flails and spacer
washers of specific thicknesses, the required number of
components can be assembled on a block in a minimum
amount of time.
Because free play is also created during the scarifying
process due to actual flail and spacer washer wear, a
certain amount of “tightness” can sometimes be
tolerated without affecting the service life of the
bushings and flails.The specific amount of “tightness”
can usually be determined through trial and error.If the
flails and spacer washers appear too tight on the
scarifier block, remove an appropriate flail or washer
and reassemble the block. If a short, operational test
indicates normal component wear patterns, the apparent
problem has been solved. A general rule for
consideration: it is better to have the flails and spacer
washers a “little too loose than a little too tight”.

Flail bushing wear is directly proportional to the amount
of force it must supply against each individual flail.When
a bushing can no longer supply adequate force against
the flails, it will break, allowing the flails to be hurdled

Because scarifier bushings are a critical component of
the actual scarifying process, it is important that each
bushing be inspected on a regular basis to determine
proper structural integrity.
Wire brushes
Typical applications include light scarifying and cleaning of
concrete, asphalt, steel and tile surfaces. Wire brushes are
secured to the machine with plastic wedges. FIGURE 12.

shear from the concrete floor material. The occurrence is
also aggravated by higher ambient temperatures. This
problem can be significantly reduced with the addition of
various amounts of water or a water saturated, fine sand
combination placed on the floor.The use of the Safety and

highly recommended to contain the water/sand slurry mixture
from damaging surrounding walls and other vertical surfaces.
FIGURE 16
The productivity of the product is directly dependent upon the
yield and tensile strength of the material being removed.
Material thickness has also shown to have a direct effect on
overall productivity. For example, the SCRAPE-R-TACH
system is a highly productive method for removing thick paint
accumulations from factory floors. Production rates of up to
several hundred square feet per hour can be realized.However,
many thin film ( ie: 5 mill thickness and thinner) urethane
coatings present a much more difficult removal problem. Since
removal rates are also directly affected by applied down force,
up to 300 lbs of external weight can be applied to the SURFACE
GRINDER to increase productivity. Cement blocks, stacked
bags of cement or weighted drums make excellent weights
and can be secured with “bungy” cords. FIGURE 17.
FIGURE 18
To index the tungsten carbide insert, proceed as follows:
Tools required:
1 each, 5/32 Allen wrench.
1) Clean the SCRAPE-R-TACH unit with a suitable safety
solvent to remove excess material build-up. Remove
as much foreign material from the female hexagon
socket area of the capscrew.This will allow the wrench
to make full contact and maximize the torque transfer
to the cap screw.
CAUTION
Follow all safety precautions for the safety solvent.
2) Remove the cap screw from the unit. Clean the newly
exposed areas of the insert and SCRAPE-R-TACH unit
with the safety solvent. Clean and inspect the threaded
holes found in older units for excess wear. New style
SCRAPE-R-TACH units feature a through hole design.

3) Index the insert to expose a new edge. Reinstall the
capscrew and apply a torque value that properly seats
the insert firmly against the body of the unit.

Multi-Segmented, Dry Diamond Disc
CAUTION
An insufficient seating torque value will allow the
insert to become loose from the unit body, resulting
in premature component wear and improper
scraping action. An excessive torque value will strip
the threads of the capscrew or unit body.
Many times increased concrete removal rates can be
achieved with the use of multi-segmented, dry diamond
discs. FIGURE 21. These discs are designed to operate
dry or can also be utilized with water. If the wet option is
chosen, an external source for providing water must be
devised. No provision for water use is provided with the
SURFACE GRINDER. Typical discs are approximately 10
inch diameter and feature up to 20 diamond segments that
are welded or brazed to each assembly.
4) Determine that the unit body is free to rotate about the
5/16 inch diameter capscrew that retains the body to
the unit. A body that does not freely rotate indicates
that a material build-up exists between the rubber mount
and retaining capscrew exits. This build-up must be
removed by disassembling the body from the unit and
cleaning all contact areas with the safety solvent.
FIGURE 20.
To install the multi-segmented, dry diamond disc, the
standard, aluminum, multi-accessory disc is first removed
from the SURFACE GRINDER. The diamond disc fastens
directly to the gimbal head with 3/8 inch diameter x 1 inch
long Allen head capscrews. FIGURE 22. The rear wheel
assembly is then placed in the lowest position to
compensate for the thickness variance of the diamond discs.

8) The SFG10E SURFACE GRINDER is not equipped with
a centrifugal clutch assembly. The electric motor is
directly coupled to the multi-accessory disc by a V-
belt/spur gear transmission.
1) The SURFACE GRINDER incorporates a rotating disc
for mounting a wide variety of multi-accessory
attachments. Direct contact with a protruding
obstruction from the floor can result in rapid and jerky
directional movement of the machine. In most operating
situations, direct contact with such an obstruction will
result in the multi-accessory attachment becoming

4) The wide variety of potential work surface materials
along with the corresponding variety of job site
environments, makes it impossible to develop a
standardized operating procedure for the SURFACE
GRINDER.Use of the SURFACE GRINDER will require
constant trial and error testing until satisfactory results
are achieved. Experience gained over time and common
sense will help minimize the amount of necessary
testing. Many factors will directly affect the operating
parameters and/or techniques utilized for a specialized
job application. Some of these factors include:
2) Productivity rates with the various multi-accessory
attachments can be increased with the addition of
external weight being applied to the area over the rotating
disc. FIGURE 36. Maximum allowable external weight
is 300 lbs. Exceeding this figure can result in permanent
structural damage to the SURFACE GRINDER.
Provisions for securing the weight by the means of
strapping or other, appropriate methods is provided.
a) Work surface material yield and tensile values. As
a general rule, these values will determine material
removal rate per unit of time. Materials with high
yield and tensile values will characteristically resist/
limit material penetration. For such materials, the
accepted procedure is to make a number of multiple
passes over the work surface rather than attempt
to make a single, deep pass. The net effect is to
actually increase productivity: more material
removed in less time. Other added benefits to this
technique are decreased vibration, less operator
fatigue and increased component service life.

b. Higher material removal rates can sometimes be
achieved by making a series of shallow passes 90
degrees to each other to form a waffle like pattern.
This technique is especially useful when removing
deeper accumulations of rubber, paint, dirt debris,
etc. from industrial floors.

6) Dust and other particle contamination can be controlled
by the following methods:
b) Water/sand slurry mixture applied directly to the
work surface can be an effective method of
reducing the effects of grinding and other material
removal processes. This method can be a
productive alternative when removing adhesives
containing asbestos. A negative effect of this
method is that the water/sand slurry mixture can
be classified as a hazardous material, requiring
proper disposal procedures.
a) The SURFACE GRINDER is equipped with a 3 inch
outside diameter vacuum tube adaptor located at
the rear of the machine. An industrial type vacuum
system and front shield assembly can be attached
to the SURFACE GRINDER to remove/control dust
and other particle contamination from the work
surface. A hose clamp is sometimes required to
properly secure the vacuum hose to the vacuum
tube. FIGURE 39.
7) Normal usage of the SURFACE GRINDER will allow
the build-up and accumulation of work surface materials
on interior surfaces. It is highly recommended that both
the interior and exterior surfaces be properly cleaned
after the completion of each usage.

Failure to properly clean the interior surfaces of the
SURFACE GRINDER can result in dried material

Early Age Grinding
Early age grinding is an alternative to floating and trowelling.
It gets it name from the fact that the concrete is ground at
an early age, after it has set but before it has gained much
structural strength. The process usually involves the
following steps:
DANGER
1) Normal screeding of the floor.
EXERCISE EXTREME CAUTION WHEN UTILIZING
ANY SOLVENTTO REMOVE ACCUMULATED MATE-
RIALS FROMTHE SURFACES OFTHE MACHINE AND
RELATED COMPONENTS. MANY SOLVENTS ARE
FLAMMABLE. DO NOT SMOKE OR INTRODUCE
FLAME INTHEWORK AREA. PROVIDE ADEQUATE
VENTILATION AND WEAR PROPER SAFETY AP-
PAREL.
2) Smoothing the floor surface with a skip float.
3) Cover the floor with polyethane sheeting.
4) Removing the sheeting and grinding the floor down a
uniform depth of approximately 1/32 inch within 24 to
48 hours of the initial pouring.
The C06 and C10 silicon carbide grinding stones are usually
used for the process, although the multi segmented, dry
diamond blades can be use as an alternative with
substantially greater productivity rates.The main benefit of
early age grinding is that it eliminates late work in cold
weather.With ordinary finishing methods, a slab cast in the
morning of a cold weather day might not get finished
trowelled until very late at night. With grinding, the
construction crew are able to leave the job at the end of a
normal work day and return 1 or 2 days later to finish the
job. Early age grinding may not reduce the total number of
work hours, but it usually eliminates the need for work at
overtime rates, which can substantially increase total project
costs.
DANGER
PROPERLY DISPOSE OF ALL ACCUMULATED MA-
TERIALS PER OSHA AND ENVIRONMENTAL
PROTECTION AGENCY CODES AND REGULATIONS.
MANY ACCUMULATED MATERIALS CAN BE CLAS-
SIFIED AS HAZARDOUS AND REQUIRE PROPER
DISPOSAL PROCEDURES. CONTACT THE APPLI-
CABLE GOVERNMENT AND/OR PRIVATE AGENCIES
FOR SPECIFIC INFORMATION.
One side benefit of early age grinding is that the process
demands less skill than conventional floating and trowelling.
This makes it an attractive process where skilled crew
personnel may not be available. It is also an excellent
procedure for concrete floors that will be eventually covered
by carpet or an applied coating.
8) On job applications where the work process creates a
considerable amount of loose material, it can become
almost impossible to determine proper material removal
depths and the extent of work already accomplished.
The problem can be compounded if a vacuum system
is not utilized. Loose material should be removed by
sweeping or other, appropriate processes and the
SURFACE GRINDER utilized until conditions again
warrant removing the accumulated material.
Definitions of floor flatness and levelness
The terms flatness and levelness have poorly understood
meanings in everyday speech, but have important
distinctions in floor construction.
STOPPINGTHE SFG10E SURFACE GRINDER
Flatness is defined as planarity or lack of curvature. A more
simple definition is that a flat floor is smooth and free of
bumps and dips. An unflat floor is bumpy and wavy.
Levelness is defined as horizontality or lack of slope. A
level floor is horizontal. A floor that is unlevel is sloped or
tilted.
1) Stopping the SURFACE GRINDER is accomplished by
moving the ON/OFF switch located on the operator
handle to the OFF position. For safety considerations,
it is also recommended that the extension cord be
disconnected from both the SURFACE GRINDER and
electric power source whenever the SURFACE
GRINDER is not in use on the jobsite
A floor can be flat, but still not level. Some floors are
specifically designed to be unlevel; they can be intentionally
sloped for drainage considerations. Very few, if any, floors
are specifically designed to be unflat. Unfortunately, many
turn out that way.Flatness and levelness are both desirable,

side forms.
The overall F numbers apply to the floor taken as a whole.
The local F numbers apply to each individual slab and are
usually only one half to two thirds the overall values.
DefinedVersus RandomTraffic Patterns
Floors are subject to two kinds of traffic patterns: defined
and random. On a defined traffic floor, vehicle movement is
confined to fixed paths. On a random traffic floor, vehicles
are free to roam, though inevitably, some traffic patterns
are used more than others.
The overall F numbers are not just simple averages. ASTM
E1155 covers how to combine F numbers.
The two tier format encourages contractors to achieve good
surface regularity while allowing for minor defects. The
attempt is to pour the entire floor to the specified overall F
numbers. If, for instance, the construction crew has a bad
day and fails to meet the specified overall numbers for the
slab, the slab can still be accepted provided it meets the
specified local numbers.
The distinction is important because the two kinds of traffic
demand different methods of measuring surface regularity.
On a defined traffic floor, a continuous (or nearly continuous)
profile in each of the paths can be measured. But where
traffic is random, the possible travel paths are infinite in
number.What usually results is statistical sampling;selected
points or lines are checked and assumed that they represent
the whole floor surface.
Such an occurrence serves as a warning to the crew that it
must strive for a better performance on later slabs, so as to
bring the overall F numbers up to the specified values. If a
slab fails to meet even the specified local numbers, it must
be repaired or replaced, but such failures seldom occur if
all parties understand what is expected from the start.
The highest degree of surface regularity is found among
the defined traffic floors. Defined traffic floors allow the
designer and contractor to focus on a limited number of
critical areas.When a defined traffic floors is out of tolerance,
it is relatively easy to identify the defects for correction—
usually by employing a grinding process.
Designers are not obligated to use this two tier format. Some
designers specify a single F number pair (Ff and Fl) which
applies to each individual slab. But this also raises the risk
that slabs will be rejected.
How to Define Surface Regularity
Since the middle 1980s, new methods of defining surface
regularity have been adopted as national standards. Older
methods will continue to be utilized, although they are less
effective. The following methods will be discussed:
1) The F number system for random traffic floors
FIGURE 40 depicts the overall and minimum F numbers
for various floor classes.The floor classification is from the
American Concrete Institute. Although the F number system
is only a few years old, it offers these advantages:
2) The TR 34 system for defined traffic floors
a) The system controls both flatness and levelness.
b) There is a standard test method.
Both methods are not of equal value. For random traffic
floors, F numbers provide the most complete and consistent
system. For defined traffic floors, the TR34 system is
superior.
c) The system recognizes the statistical nature of profile
testing on random traffic floors.
d) The system is infinitely variable.

ASSEMBLY INSTRUCTIONS/OPERATIONS
The Superflat category is intended for very narrow aisle
warehouses where the highest standards are required.
Category 1 is suggested for very narrow aisle warehouses
where the vertical lift height is between 26 and 43 feet.
Category 2 is for very narrow aisle warehouses where the
vertical lift height is under 26 feet and the use of low rise,
automatically controlled vehicles. No matter which category
of surface regularity is specified, it is accomplished by
measuring elevations on 12 inch centers.This is very similar
to an F number survey, but with an important distinction. In
an F number survey, the elevation profiles are made on the
floor at random. With the TR 34 System, the survey
measurements are made on the actual paths of the vehicles
that will utilize the floor.
FIGURE 40
Improving the wear resistance of concrete floors by
grinding with the SFG10E SURFACE GRINDER
Poor wear resistance can often be traced back to a surface
that is weaker than underlying levels of the pour. This
occurrence can result from bad finishing techniques,
improper curing or early freezing.
One of the major limitations of the F number system is that
it does not control the surface regularity at joints. Because
joints are statistical anomalies, the standard test method
forbids measurements within 24 inches. The designer
specifying by F number has two methods to accommodate
the problem.The first solution is to locate joints at locations
where surface regularity is not important. The second
solution is to design specifications for the joints themselves.
Where surface weakness is a problem, grinding can be a
solution.The process is similar to the early age technique.
The grinding depth is typically 1/16 to 1/8 inch. A large
project should not be attempted until a small test area has
proven that the technique will produce the desired results.
Usually only a square yard of floor is ground with the normal
wear tests performed.
TheTR 34 tolerances for defined traffic floors
The TR 34 System divides defined traffic floors into three
categories:
Repair costs can be minimized by grinding only those floor
areas that accommodate traffic. For example, in a pallet
rack warehouse, it may be necessary to grind only the aisle
areas and not under any of the racks.The grinding process
can adversely affect the surface regularity. Where specific
properties are important, it may be necessary to survey
the floor during the grinding process to ensure that flatness
and levelness specifications are maintained.
a) Superflat
b) Category 1
c) Category 2
For each category, the TR 34 System specifies limits for
three properties:
Cleaning concrete floors to improve the wear resistance
with the SFG10E SURFACE GRINDER
Property 1 is the difference in elevation between two points
12 inches apart, measured in the direction of vehicle traffic.
This is the levelness tolerance.
Clean concrete floors have a longer service life than dirty,
poorly maintained floors. Loose debris produces three-bodied
wear by allowing particles to roll between the traffic and the
floor surface. With some types of debris, especially when
lodged in vehicle wheels, wear can be immediate and
severe.
Property 2 is the difference in slope over 24 inches
measured in the direction of vehicle traffic. This is the
flatness tolerance. It is identical as the 24 inch curvature
utilized in the F number system.
The SFG10E SURFACE GRINDER can be utilized with a
number of multi accessories to clean and extend concrete
floor service life. The SCRAPE-R-TACH® floor coatings
removal system readily removes food, oil and rubber
accumulations from high traffic floor areas. The Clean
Sweep™ silicon impregnated, rotary brushes along with a
biodegradable detergent applied to floors removes ground
in dirt and debris from shop and industrial floors.Dry diamond
segmented discs and blocks can be utilized to remove
surface imperfections.
Property 3 is the difference in elevation between opposite
points in the left and right wheel path, measured
perpendicular to the direction of vehicle traffic. As with
Property 1, it is a levelness tolerance. The TR 34 System
specifies different values for Property 3 depending upon
whether the distance between left and right wheel paths is
more or less than 5 nominal feet

CHECKINGV-BELTTENSION AND ALIGNMENT
Maintenance/Service
PREVENTATIVE MAINTENANCE CHECK LIST
ProperV-belt tension and alignment are essential for smooth
transmission of horsepower and extended service life.
Improper tension and alignment will accelerateV-belt wear
and contribute to decreased productivity. The V-belt is
tensioned at the factory with the maximum recommended
tension force. Check the belt tension at least two times
during the first day of operation as there will normally be a
rapid decrease in belt tension until it has been run in. Check
the belt tension every eight hours of operation thereafter
and maintain tension within the recommended range. The
correct operating tension for a V-belt drive is the lowest
tension at which it will not slip under peak load conditions.
The normal operation of the SURFACE GRINDER produces
extreme dirt and dust, along with levels of random vibration.
Before operating the SURFACE GRINDER, the following
service list should be accomplished.This list is for reference
only and is not intended to be all inclusive. Other subject
areas can be added at the discretion of the owner(s) and/or
operator(s):
1) Check all fasteners for proper torque values. If a fastener
requires re-torquing, consult a torque chart for proper
value. Properly discard and replace any worn fastener
with a factory approved, replacement part.

a) Do not install replacement belt if the pulleys have
excessively worn grooves. Such pulleys should be
replaced to insure proper belt fit. Operating the V-
belt in worn pulley grooves will accelerate wear, 3) Remove the belt guard from the main frame. Clean the
reduce horsepower and torque levels and
significantly reduce component service life.
inside of the belt guard with an appropriate safety
solvent. Check for signs of wear and damage. Secure
in a proper storage area.
b) AV-belt should never be forced over a pulley.More
belts are broken from this cause than from actual
failure in service.
CAUTION
c) Keep the belt as clean and free of foreign material
as possible. Do not use belt dressing
Observe all applicable safety precautions for the
solvent.
6) Rotate the take-up cap screws clockwise until the V-
belt has enough tension to not allow it to fall off the
pulleys.
4) Tilt the SURFACE GRINDER back until the operator
handle comes in contact with the surface. Appropriate
wheel chocks are recommended.
REPLACINGTHE LORD®TYPE ELASTOMERIC MOUNTS
ONTHE MULTI-ACCESSORY DISC
Lord® type elastomeric rubber mounts are utilized to allow
each multi-accessory disc to maintain full contact with the
work surface.The rubber mounts afford a constant flex rate
for the multi-accessory disc throughout its service life.The
rubber compound is resistive to the effects of ultraviolet
radiation and most common chemicals encountered when
operating the SURFACE GRINDER .
5) Utilizing the Allen wrench, remove the affected
aluminum multi-accessory disc (if still attached) from
the SURFACE GRINDER.
6) Utilizing the 9/16-inch wrenches, remove the cap screws
that retain the Lord® rubber mounts to both the mounting
plate and transmission shaft.
During the manufacturing process, the rubber mounts are
pressed into specially machined cavities in the disc
mounting plate. Under normal usage and job applications,
the Lord® type rubber mounts will deliver appropriate
performance for the expected service life of the SURFACE
GRINDER. However, an attachment mounted in the multi-
accessory disc that directly strikes a vertical floor
obstruction with sufficient impact force can cause one or
more of the mounts to become separated from the mounting
plate. This occurrence will not allow the multi-accessory
disc to maintain full contact with the work surface. This
occurrence is also intended to protect the transmission gears
and bearings from costly damage and the operator from an
impact force that could cause personal injury.
7) Inspect the appropriate cavities in the mounting plate
for wear and damage. Any nick or burr must be removed
by the use of an appropriate file, followed by the use of
240 grit sandpaper.
8) Apply the installation lubricant to the exterior surface
of the elastomeric mount to minimize damage when
pressing into the mounting disc. If the factory supplied
lubricant is not available, an acceptable alternative is
the use of common liquid soap.
Tools Required:
1 each, 5/16 allen wrench.
2 each, 5/8 wrenches.
1 each, arbor press of sufficient capacity and stability.
Parts Required:
Elastomeric Mount, P/N SFJ62502 (as required).
1 container each: Installation Lubricant (or approved
equivalent).

MAINTENANCE/SERVICE
LUBRICATION REQUIREMENTS
CAUTION
Parts Required:
Do not install an elastomeric mount without the use
of an approved lubricant. Installation without an
approved lubricant can produce tears in the mount,
resulting in substandard operational performance
and service life.
1 each, standard grease gun filled with one of the following:
ESSO Beacon 325, Shell Alvania #2, Chevron SRI, or
equivalent.
1 each, container of dry film lubricant.
9) Support the elastomeric mount, socket and mounting
plate as depicted in FIGURE 50. The mounting plate
must be suspended from the arbor press to allow the
mount to clear when the pressing process is completed.
A short section of 1-1/2 inch inside diameter steel tubing
can be utilized for this purpose. Using the arbor press,
apply a steady force in a straight line direction to the
mount until it fully penetrates the cavity in the mounting
disc. Do not attempt to push the elastomeric mount
through the mounting disc with excessive force.
Damage to the elastomeric mount will result.
1) Lubricate the caster wheel bearings with a dry film
lubricant only.Dry film lubricants dry immediately upon
contact. Use sparingly.Excess lubricant will attract the
fine grained, powdered materials described and directly
affect bearing service life.
CAUTION
Do not lubricate the caster wheels with any type of
grease material. Grease will attract foreign material
accumulations that can accelerate bearing wear.
10) Reassemble the mounting disc to the transmission shaft.
11) Reassemble the mounting plate to the mounting disc.
2) The transmission gears are supported by extra capacity,
ball bearing units. Bearings are lubricated at the time of
manufacture and do not require additional servicing
when placing the unit in initial service. Zerk grease
fittings can promote improper service schedules and
an excessive amount of over lubrication. Excess
grease escaping from around the bearing insert seals
will attract foreign material accumulations that can
drastically shorten their service life.Excessive amounts
of grease in the bearing race cavity can actually
increase friction and resulting heat increases that can
also dramatically shorten bearing service life.
12) Reassemble the aluminum multi-accessory disc to the
mounting plate.
13) Check to determine that the replacement elastomeric
mounts allow for proper position of the aluminum multi-
accessory disc. If the elastomeric mounts are not
properly positioned, they will require removal and
reinstallation.The removal process can produce tears
and abrasions in the mount that will require new
replacements.

MAINTENANCE/SERVICE
3) The transmission gears are lubricated at the time of
assembly with approximately 24 ounces of Lubricate
GR132 grease or equivalent.This lubricant has an EP
additive to better allow it to cling to the gears. The
transmission should not require additional lubrication
or the lubrication to be changed until service work to
the gears is performed. FIGURE 51.
4) Standard greasing intervals will range from once every
8 hour work day to approximately once every work week.
Always maintain sufficient grease around the
circumference of the bearing insert to provide its self-
aligning feature and prevent the formation of corrosion.
5) Do not apply belt dressing materials to the V-belts for
the purpose of minimizing slippage. These products
typically attract foreign material accumulations that can
accelerate component wear.ExcessiveV-belt slippage
can be eliminated with proper V-belt tension and
alignment.
ELECTRIC MOTOR SERVICE
The electric motor is capable of operating for many years
with a reasonably small amount of maintenance. Before
attempting to service the motor, disconnect the SURFACE
GRINDER from the power source. Clean the motor surfaces
periodically, preferably with a vacuum cleaner. Heavy
accumulations of dirt and lint will result in overheating and
premature failure of the motor.
The electric motor is equipped with higher capacity ball
bearings and under normal service and ambient temperatures
should not require relubrication for many years. If you feel
that the motor requires relubrication, contact the local
representative of the motor manufacturer for specific
information.
The seals utilized with the motor are intended to deliver a
longer service life in a concrete dust environment. When
replacing the seals, utilize only components meeting the
original factory specifications.
