SILICOSIS/RESPIRATORYWARNINGS
WARNING WARNING
SILICOSIS WARNING
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

C-30HDN PUMP — GENERAL INFORMATION
The following operating principles and operating suggestions
As a general rule, the use of approximately six sacks of cement,
70% washed concrete sand and 30% #4 pea gravel per yard of
concrete will result in a pumpable mix.The ideal nature of sand
and rock in certain areas may permit you to increase the
percentage of rock or adjust the mix considerably to meet the job
requirements.When possible, you may experiment with various
mixes in your area to determine the degree of versatility of the
Direct-flo Pump.
should prove helpful in the successful operation of your concrete
pump.Your new “small line”concrete pump has been designed
to give you many years of service when operated properly. A
study of the following paragraphs is important to the successful
operation of your new Direct-flo Concrete Placer.
All concrete pumps require a high level of operator skill and
more frequent service than most of the other construction
equipment.The highly abrasive nature of concrete under pressure
makes it extremely important that expendable wear components
be inspected at regular intervals between jobs to prevent having
to replace these items during a pour.
Uniform gradation of the washed concrete sand and the 1/2”
minus aggregate along with sufficient cement content and water
are important to a successful pump operation.
A recommended pumpable mix design would be 70% sand and
30% aggregate-cement content to be a minimum of 6 sacks.
(564 lbs.)
Experience has proved that inconsistency of batched concrete
mixes and frequent moving of the line requires the operator to
be readily available at all times during pumping to stop the pump
and prevent abuse to the unit which may occur if unexpected
blockages develop.
Your local sand and rock engineers will
give you the S.S.D.weights of sand and
rock required in your local area which
will yield one cubic yard per the above
recommendation.
PUMP MIX GUIDELINES
When ordering concrete, be certain to advise the concrete
supplier that you require a “pump mix”.The Direct-flo manifold
will pump a wide variety of materials, but certain basic principles
must be followed to assure successful pumping, as follows:
SAMPLE DESIGN MIX-3000 PSI 3/8" SLUMP 4"- 5"
Type II Cement
Sand
6.49 sack/cu. yd
Sat. Surf. Dry
Sat. Surf. Dry
Sat. Surf. Dry
48 Gallons
611 lbs.
2000 lbs.
864 lbs.
0 lbs.
Generally speaking, the washed concrete sand and #4
aggregate (pea gravel) should conform to A.S.T.M.standards in
regard to sieve analysis. Sands in some areas are washed clean
of the #100 and #200 mesh fines, which results in separation
and jamming in the manifold while pumping under pressure.
#4 Gravel
#3 Gravel
Water
400 lbs.
3,906 lbs
26 oz.
If this condition develops, check with your concrete suppliers
engineers and get their recommendations for supplementing
the lack of the fines.The use of locally accepted ad-mixes may
be required.(For example, Pozzolith, Bentonite Clay, Plastiments,
etc.)When properly prescribed, additives form the plastic paste
sometimes necessary to hold the cement and aggregate together.
TotalWeight
AdmixtureWRDA-79
Water 7.40 gal/sack
Test laboratory data has proven in many areas that the above
mix guidelines have produced concrete rated at 3000 psi (28
day test) and upwards of 5000 psi with an increase in cement.
In some areas where the gradation of sand and rock is ideal and
sufficient cement is used along with admixtures, the Mayco small
line concrete pump will handle up to a 50-50 ratio of sand and
rock.
If jamming conditions in the pump or
hose occur for any reason at all, DO
NOT attempt to use more power to
correct the condition.
When the mix is designed for wet gunning applications, it is
normal to increase the cement (up to 7.5 or 8 sacks) and change
the sand to rock ratio to 85% sand and 15% rock.
Determine the cause of jamming, correct it and resume pumping.
Trying to force material through under jammed conditions may
result in damage to the drive system, thus voiding any warranty
services.
The Mayco concrete pump will valve efficiently when using
cellular-foam concrete mixes upwards of 70 lbs. per cubic foot
wet density. (Below 70 lbs. materials (roof decks) the valving
becomes inefficient.)

C-30HDN— HOW IT WORKS
An automatic, centrifugal clutch is installed to engage and
disengage the pumping action without stopping or starting the
engine.The centrifugal clutch is set at 1100 R.P.M.The engine
idle speed is approximately 875 R.P.M.;therefore, the clutch is
completely disengaged at idle. The throttle settings while
pumping should always maintain an engine R.P.M. high enough
to prevent the clutch from slipping and burning the clutch lining.
The MAYCO concrete pump has one main pumping piston
which is valved by means of two ball checks. (A inlet, and B
outlet.)
The secondary piston is used as a compensator piston to
smooth out the pulsations of a single piston action. Note:The
compensator will not start operating until material is pumped
into the line and back pressure develops.
The return spring which is installed on the rocker arm, is installed
to eliminate shock and stress between the cam roller and the
cam weldment when the pump is in operation. If the return spring
is removed or replaced for any reason, maintain the backing
plate dimension of 3” as shown on Figure 3, to produce the
proper pre-loading of the spring for a smooth performance.
The compensator spring, which is installed on the
compensator piston rod, deflects with each piston stroke.This
“spring cushion”, in conjunction with the cam profile, produces
and uninterrupted smooth flow of material under average
pumping conditions.
The pumping cylinder (Figure 7) retracts drawing the material
past the ball (A) and filling the cylinder.The compensator piston
is pumping the material out to the nozzle and causing ball (B) to
seat preventing the material from returning to the pumping
cylinder intake.
Figure 7. Pumping Cylinder

C-30HDN PUMP — HOW ITWORKS
The pumping piston (Figure 8) is forcing the material past ball
(B) and out to the nozzle, also seating ball A so that the material
will not flow back to the hopper. This action also fills the
compensating piston for the next stroke.
Figure 8. Pumping Pistons
The return spring is installed to eliminate shock and stress
between the cam roller and the cam weldment when the pump is
in operation. If the return spring is removed or replaced for any
reason, maintain the backing plate dimension (3-inches) as
shown to produce proper pre-loading of the spring for a smooth
performance.
Figure 9 shows the relationship between the return spring, the
compensator spring and the rocker arm to maintain a smooth
performance. DO NOT tighten the bolt (Item 1) completely, the
rod end must be able to move.

Downhill pumping can be difficult on some jobs. The slurry
procedure would be the same as explained on the pages titled
Operating Suggestions. It is suggested that a sponge 2”x 4”x 6”

had excessive wear and need replacement. Once they have
reachedacertainwearpoint,theymay“channelout”rapidlyand
material will reciprocate past the ball on each stroke.
The reason for using the wet sponge is to keep the slurry from
running too far ahead of the concrete and so reducing the
possibilityofseparation.Whenthepumpisstopped,thematerial
can flow slowly down, due to gravity, and cause the hose to
collapse.

Pulsation
Whenpumpingverticallyupthesideofabuilding,above40feet,
we would recommend the installation of steel pipe securely
fastened at intervals as necessary to support the pipe. Ninety
degree, long radius pipe sweeps should be installed at the top

C-30HDN PUMP —TOWING GUIDELINES
Towing Safety Precautions
■
Check wheel mounting lug nuts with a torque wrench.
Torque wheel lug nuts as described in the "Lug NutTorque
Requirements",Table 5.
CAUTION - LocalTowing Regulations
■
■
■
Make sure brakes are synchronized and functioning properly.
Check tightness of suspension hardware (nuts and bolts).
Check with your county or state safety towing regulations
department before towing your concrete pump.
Avoid sudden stops and starts.This can cause skidding, or
jackknifing. Smooth, gradual starts and stops will improve
gas milage.
To reduce the possibility of an accident while transporting the
pump on public roads, always make sure that the trailer and the
towing vehicle are in good operating condition and both units
are mechanically sound.
■
■
■
Avoid sharp turns to prevent rolling.
Retract wheel stand when transporting.
DO NOT transport pump with fuel in the fuel tank.
The following list of suggestions should be used when towing
the pump:
■
Make sure that the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
CAUTION - NEVER Use Defective Couplers
If the trailer coupler is deformed replace entire coupler.NEVER
tow the pump with a defective trailer coupler. There exist the
possibility of the trailer separating from the towing vehicle.
■
ALWAYS inspect the hitch and coupling for wear. NEVER
tow the light tower's trailer with defective hitches, couplings,
chains etc.
PumpTrailerVehicle Connection
■
■
■
■
CHECK the tire air pressure on both the towing vehicle and
the trailer.Also check the tire tread wear on both vehicles.
1. Check the vehicle hitch ball, and trailer coupler for signs of
wear or damage. Replace any parts that are worn or
damaged before towing.
ALWAYS make sure the trailer section of the pump is
equipped with a "Safety Chain".
2. Use only the 2-inch ball diameter with a towing capability of
5,000 lbs. (2,268 kg) as indicated on the trailer's coupler.
Use of any other ball diameter will create an extremely
dangerous condition which can result in separation of the
coupler and ball or ball failure.
ALWAYS attach trailer's safety chain to frame of towing
vehicle.
ALWAYS make sure that the vehicle and trailer directional,
backup, brake, and trailer lights are connected properly and
are working properly.
3. Be sure the coupler is secured to the hitch ball and the lock
lever is down (locked).
■
Remember in most cases the maximum speed unless
otherwise posted for highway towing is 45 MPH, however
before towing your pump, check your local state, and county
vehicle towing requirements. Recommended off-road towing
is not to exceed 10 MPH or less depending on type of terrain.
4. Attach safety chains as shown in Figure 2. Remember to
cross the safety chains.
5. After towing for about 50 miles recheck the entire towing
system for tightness.
■
■
Place chocked blocks underneath wheel to prevent rolling,
while parked.
Recommended Maintenance
1. Smear ball socket and clamp face with chassis grease.
Periodically oil pivot points and were surfaces of coupler
with SAE 30 W motor oil.
Depending on soil conditions and location it may be
necessary to place support blocks underneath the trailer's
bumper to prevent tipping, while parked.
2. When parking or storing the concrete pump, keep the coupler
off the ground so dirt and other debris will not build up in the
ball socket.
■
Inflate tires to correct pressure, inspect tires for cuts, and
excessive wear. SeeTable 3 (TireWearTroubleshooting).

C-30HDN PUMP —TRAILER SAFETY GUIDELINES
Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical components
of the trailer. When specifying or replacing the trailer wheels it is
important the wheels, tires, and axle are properly matched.
CAUTION - GeneralTrailer Safety
DO NOT attempt to repair or modify a wheel. DO NOT install
an inter-tube to correct a leak through the rim. If the rim is
cracked, the air pressure in the inter-tube
may cause pieces of the rim to explode
(break-off) with great force and can cause
serious eye or bodily injury.
TiresWear/Inflation
Tire inflation pressure is the most important factor in tire life.
Pressure should be checked cold before operation. DO NOT
bleed air from tires when they are hot. Check inflation pressure
weekly during use to insure the maximum tire life and tread
wear.
Torsion Bar Suspension
The torsion bar suspension and associated hardware
(Figure 3) should be visually inspected every 6,000 miles for
signs of excessive wear, elongation of bolt holes, and loosening
of fasteners. Replace all damaged parts (suspension) immedi-
ately.
Table 3 (TireWearTroubleshooting) will help pinpoint the causes
and solutions of tire wear problems.
ALWAYS wear safety glasses when
removing or installing force fitted
parts.Failure to comply may result in
serious injury.

Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the fasteners
matched to the cone angle of the wheel. Proper procedure for
attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (Figure 4). DO NOT torque
the wheel lug nuts all the way down.Tighten each lug nut in
3 separate passes as defined byTable 4.
3. Afterfirstroaduse,retorquealllugnutsinsequence.Check
all wheel lug nuts periodically.

3. ALWAYS carry extra“O”rings.
5. It is important that the hinged discharge cone on the pump
manifold be opened and all remaining concrete (rock and
sand) be thoroughly washed out.This must be done after
each job to prevent concrete build up in the discharge
manifolds and 3”discharge elbow.
4. Keep entire pump clean of concrete to prevent build-up.
5. ALWAYSgreaseeveryfittingdaily.Useonlypremiumgrade
grease.
Over greasing will not damage

Piston CupWear
NOTE
The rubber piston cups are a natural wear component and
will require periodic replacement. The life of the rubber cups
depends on many factors, proper oil level, oil cleanliness,
abrasiveness of aggregrate being pumped and material slump
etc.
General Clean-up Procedure
1. Ensure that there is no blockage in the hose and line
(PumpingTips, step 8) or in the manifold (PumpingTips,
step 7). If a blockage exists, clear it to ensure proper
operation the next time it is used.At the end of every pour,
or during long delays during a pour, the pump and deliv-
ery system must be thoroughly cleaned by removing all
concrete material.
IMPORTANT! To ensure maximum
cup life, the oil level in the lubrication
box must be maintained at the
NOTE
proper level. In addition the
lubrication box must be cleaned
periodically.
2. Proper wash out of all materials or build up within the
pump manifold and hoses following the pumping opera-
tionwillpreventproblemswhenstartingthenextjob.After
completion of the pour, pump the remaining concrete in
the hopper through the discharge line.
As the rubber piston cups wear, fine cement particles will
accumulate in the bottom of the lubrication box. Once this cement
paste reaches 1-inch in height, it is recommended that the
lubrication box be drained (flushed) and cleaned and the oil
replaced with new SAE 30 motor oil.
Toavoidthepossibilityofseparation
during clean-up, do not pump the
concrete below the inlet ball in the
hopper. It is best to leave approxi-
mately3to4inchesofconcreteabove
the inlet ball.
NOTE
There are two clean-out ports
NOTE
located at the bottom of the
lubrication box.
Any questions regarding the lubrication box clean-out procedure,
contact the MAYCO Service Department.

C-30HDN PUMP — MAINTENANCE (PUMP)
Roller Chain Application
Installation and Drive Alignment
A properly selected, installed and maintained drive chain
(Figure 28) is an extremely versatile means of power transmission.
It is possible, however, to greatly reduce a chain’s life and even
induce failure if the chain is abused through improper installation,
operating or maintenance procedures. In certain applications,
failure can lead to personal injury or property damage.
Chain and sprockets (Figure 29) must be installed correctly.
Sprockets must be properly aligned and sprocket shafts must be
parallel so the drive will run in a plane perpendicular to them.
Axial alignment should be checked with a straight edge which
will extend across the finished sides of the sprockets.They should
be true-running with minimum wobble and eccentricity.The higher
the drive speed, the more important these details become.
Figure 28. Drive Chain
Recommendations and comments on how to get the most from
your roller chain drive are given in this section.The drive chain
used in the MAYCO C-30HDN pump is manufactured by the
"DIAMOND CHAIN COMPANYTM"
Figure 29. Shaft and Drive Sprocket Alignment
The chain should be installed so the slack span is properly
tensioned.To check chain tension (Figure 30), turn one sprocket
to tighten the upper span of the chain while holding the other
sprocket fixed.The lack span should have 4-6% of span length
in the mid-span movement for horizontal drives and 2-3% for
vertical drives.
Working Loads
UTS-Ultimate Tensile Strength-is the one time pull required to
break the chain. For single strand chain, the load (pull) applied
to the chain in service should never exceed 1/6th of the UTS for
the chain being used except as noted below.
It is possible to exceed the allowable working loads for a limited
number of cycles, but you should contact Diamond Chain
Company before this is considered. A roller chain should never
be loaded above 50% of UTS for even one cycle.To do so
will damage the chain structure and reduce its capacity.
The UTS or one time breaking load of multiple strand chain is
the UTS of a single strand chain times the number of strands; i.e.,
two strand chain is twice as strong as single.
Figure 30. Drive ChainTension
A roller chain’s capacity can be significantly reduced if it is twisted
or bent sideways in the direction of the pin axis. Exercise
particular care in alignment of hoist or other applications where
loads are suspended near personnel.
When allowable working loads are considered, however, the
capacity of each strand in a multiple strand chain is only 65% of
the single strand rating; thus, three-strand chain would rate not
three times single but only 1.95 times.This is because the chain
load cannot be exactly distributed across all three strands of the
three-strand chain.

C-30HDN PUMP — MAINTENANCE (PUMP)
Drive Chain Lubrication
The clearance between pin and bushings is very small
(Figure 31), on the order of .003 to .005 inches. A lubricant must
be thin enough to flow into the chain. SAE 30 weight oil is about
right for room temperature. Lighter oil should be used for lower
ambients and heavier for higher operating temperatures. Grease
should not be used as it cannot penetrate chain clearances.
As a chain articulates in entering and leaving a sprocket, there
is relative movement between pin and bushing surfaces.These
surfaces wear causing chain elongation. If a lubricant film can
be maintained between the pin and bushing, the wear rate is
very slow and the chain wear life very long. Maintaining the oil
film is relatively simple at low speeds but becomes increasingly
difficult as the speed increases.
It is recognized that good lubrication is not possible in many
applications, so shorter wear life must be accepted in these
situations.
In general, chain wear leads to rough or unsatisfactory service
prior to actual chain breakage. Good lubrication can help to
prevent chain failure by providing protection against rust or
corrosion. Rusting can allow pits to form in the surfaces of the
chain parts causing stress concentration points.This can lead to
chain failure at relatively low loads.

Assembling and Disassembling Drive Chain
CAUTION - Drive Chain Safety
Chain-Link Pin Removal
1. Ifchainisofcotterpin-typeconstruction, removecotters.
2. Ifchainisrivetedtypeconstruction,grindpinheadsoffsopin
ends are flush with the linkplate.
You may be seriously injured if you attempt to install the drive
chain while the pump is running. TURN-OFF the engine and
lock out gears and sprockets before attempting installation.
3. Drive pins out of linkplate using a Diamond pin extractor
ModelP/N113or135.Somemultiplestrandchainsorlarge
pitch models will require a hammer and punch or a press to
removethepins.
Once installed, the drive chain must be guarded to prevent
personal injury or properly damage in the event the chain
separates during operation. NEVER run pump with drive chain
guard removed.
Installation Of Coversides
Diamond Chain coversides are manufactured three different
ways:
CAUTION - Eyesight Hazard
■
■
■
Slip Fit
The components of the drive chain are hardened parts.Striking
these parts may cause metal chips to break off from the chain
or the tools used resulting in personal injury.
Modified Press Fit
Full Press Fit
Modified and Full Press Fits require
some patience and tools to assemble
and/or disassemble. Use vice grips,
plumbers pliers or a small hammer to
drive coversides onto pins.
During all stages of chain disassembly
and assembly, wear safety glasses to
prevent metal parts or chips from entering
your eyes and have personnel in the
immediate area do likewise.
NOTE
Installation of Spring Locks and Cotter-Pins
After coversides have been installed, install spring locks or cotters
(depending on chain design). Avoid using bent or worn cotters
or spring locks. After spring locks (or cotters) are installed, lightly
tap pin ends to position these parts snug against the coverside
for additional support.
Tips To Remember
■
■
Chian will break if mused or abused
Serious injury or property damage can result if chain is
installed incorrectly.
■
Select, install, guard and maintain chain in accordance with
equipment manufacturer and "Diamond Chain Company's
recommendations.
■
■
Read chain assembly instructions before attempting to install
chain on pump sprocket wheel.
Knowing more about how the chain is constructed may help
in assembly and disassembly. Further information may be
obtained by calling or writing Diamond Chain CompanyTM.

APPENDIX — C-30HDN CONCRETE MIX INFORMATION
The following information has been extracted from actual testing laboratory reports. The purpose of this printing is only to help
create a better understanding of the importance of uniform gradation and proportioning of materials which affect pumpability of
concrete mixes.These weights and proportions illustrate that when the sieve analysis is ideal, the sand/rock ratio can be adjusted
(65% sand 35% rock) and pumpability should be excellent.

General recommendations
■
If the site will permit, use steel pipe from the pump
to the pool perimeter. It will reduce line pressures
which is highly recommended.
■
■
The vibrator on the reducer by the pool improves
pumpability.
Turn both air vibrators off whenever the pump is
stopped to prevent separation of mix.
■
■
The air vibrators are low consumption (4.2 scfm).
Leave the air on at the nozzle when the pump is
stopped to prevent clogging of air the hoses in the
air insert.
■
Use item #11 (steel elbow) at the edge of the pool
to prevent collapse of the rubber hose, which can
cause blockage.
