SAFETY PRECAUTIONS
Tool operators and maintenance personnel must always
comply with the safety precautions given in this manual
and on the stickers and tags attached to the tool and
hose.
•
•
Do not operate the tool at oil temperatures above
140 °F/60 °C. Operation at higher oil temperatures
can cause operator discomfort and may damage the
tool.
These safety precautions are given for your safety. Re-
view them carefully before operating the tool and before
performing general maintenance or repairs.
To avoid personal injury or equipment damage, all
tool repair, maintenance and service must only be
performed by authorized and properly trained per-
sonnel.
Supervising personnel should develop additional pre-
cautions relating to the specific work area and local
safety regulations. If so, place the added precautions in
the space provided in this manual.
•
•
•
•
•
•
•
•
•
Do not exceed the rated limits of the tool or use the
tool for applications beyond its design capacity.
Always keep critical tool markings, such as labels
and warning stickers legible.
The CR27 Hydraulic Circular Saw will provide safe and
dependable service if operated in accordance with the
instructions given in this manual. Read and understand
this manual and any stickers and tags attached to the

mended by Stanley Hydraulic Tools.
Check fastener tightness often and before each use
daily.
Do not wear loose fitting clothing when operating the
tool.
Keep all parts of your body away from the rotating
saw blade.
•
Operator must start in a work area without bystand-
ers. The operator must be familiar with all prohibited
work areas such as excessive slopes and danger-
ous terrain conditions.
Keep the saw blade off all surfaces when starting
the circle saw.
Do not reverse saw blade rotation direction by
changing fluid flow direction.
•
•
•
Establish a training program for all operators to en-
sure safe operation.
Without the use of non-conductive accessories, this
tool is not for use near energized electric lines. Fail-
ure to comply with this warning could result in seri-
ous personal injury.
Do not operate the tool unless thoroughly trained or
under the supervision of an instructor.

ance at all times.
CIRCULAR SAW SPECIFIC SAFETY
PRECAUTIONS
Do not inspect or clean the tool while the hydraulic
power source is connected. Accidental engagement
of the tool can cause serious injury.
•
Do not rely exclusively upon the safety devices built
into the saw. As a circle saw user, several steps
must be taken to keep your cutting jobs free from
accident or injury.
•
Supply hoses must have a minimum working pres-
sure rating of 2500 psi/175 bar.
•
•
Be sure all hose connections are tight.
•
•
Ensure the saw blade is correctly mounted and
tightened before each use.
The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling the tool.
Wipe all couplers clean before connecting. Use only
lint-free cloths. Failure to do so may result in dam-
age to the quick couplers and cause overheating of
the hydraulic system.
Keep a good firm grip on the pole saw with both
hands. Place your right hand on the rear handle and
your left hand on the outer tube assembly when op-
erating. Use a firm grip with your thumbs and fingers
encircling the saw handle and outer tube assembly.
A firm grip helps keep control of the saw. Do not let
go.
•

SAFETY PRECAUTIONS
•
Ensure that the direction of rotation of the saw blade
is as prescribed in this manual.
•
•
Use extreme caution when cutting small branches.
Twigs may catch the saw blade and be whipped to-
ward the operator or pull the operator off balance.
•
•
Cut at the rated operating speeds (gpm).
Only use saw blades manufactured by Stanley Hy-
draulic Tools. Stanley assumes no responsibility for
failure in equipment, accidental damage or acciden-
tal injury as a result of the use of saw blades not
manufactured by Stanley Hydraulic Tools.
Operate the saw at “no load” for 30 seconds in a
safe position and ensure there is no excessive vi-
bration or other defects detected. If considerable vi-
bration or other defects are detected, stop operation
of the tool immediately and determine the cause. Do
not use the tool until the defect is corrected.
•
•
•
Always assure the saw blade is sharp. Do not try to
use the tool with a dull saw blade.
•
•
•
If the tool is dropped with a saw blade installed, the
saw blade should be examined.
Keep the handle dry, clean and free of hydraulic
fluid.
Make sure you’re well rested and mentally alert be-
fore operating the saw.
When using tools near energized transmission lines,
make sure to use only hoses labeled and certified
non-conductive.
Do not start cutting until you have a clear work area,
secure footing and a planned drop area for falling
branches.
•
•
•
Turn off the power unit or move the hydraulic control
valve to neutral before setting the pole saw down.
•
Keep all parts of the body away from the saw during
operation.
Know the location of buried or covered electrical
services before starting work.
•
•
Carry the saw with the unit de-energized.
To avoid personal injury or equipment damage, all
tool repair, maintenance and service must only be
performed by authorized and properly trained per-
sonnel.
Do not operate a pole saw that is damaged, improp-
erly adjusted or not completely and securely assem-
bled. Make sure the saw blade stops moving when
the control trigger is released.

accidental contact with overhead electrical conductors
and/or communication wires and cables. (Ref. ANSI
Z133.1-1982)
the truck supporting the device is considered to be ener-
gized and contact with the truck must be avoided except
when emergency rescue procedures are being carried
out. Emergency rescue should only be attempted by
properly trained personnel familiar with electrical haz-
ards.
All overhead conductors and all communications wires
and cables are considered to be energized with poten-
tially fatal voltages and must never be touched either di-
rectly or indirectly. Accidental contact with any overhead
conductors or communication wires and cables can re-
sult in death or serious injury.
Storm work and emergency conditions create special
hazards. During these conditions, only authorized tool
operators shall perform any tree operation.The follow-
ing guidelines must be followed to prevent accidental
contact with overhead electrical conductors and/or com-
munication wires and cables. (Ref. ANSI Z133.1-2000)

HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-
draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-
ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near
electrical conductors.
Fabric-braided (not certified or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-
ner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certified non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydraulic
Tools. DO NOT REMOVE THESE TAGS.

OPERATION
SETTING FOR OPEN-CENTER (OC) OR
CLOSED-CENTER (CC) OPERATION
PREOPERATION PROCEDURES
PREPARATION FOR INITIAL USE
1. To set the tool for open-center (OC) system opera-
tion turn the selector screw located in the top of the
valve spool fully out (counter-clockwise) until it hits
the stop.
Each unit as shipped has no special unpacking or as-
sembly requirements prior to usage. Inspection to as-
sure the unit was not damaged in shipping and does not
contain packing debris is all that is required. After instal-
lation of a saw blade a unit may be put to use.
2. To set the tool for closed-center (CC) system opera-
tion turn the selector screw located in the top of the
valve spool fully in (clockwise) until it bottoms.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops a
flow of 5–7 gpm/19–26 lpm at 1000–2000 psi/70–
140 bar.
TO DISABLE DUAL SPOOL OPERATION
AND CONVERT TO OPEN-CENTER ONLY
OPERATION
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100–2250 psi/145–
155 bar minimum.
1. Turn the selector screw located in the top of the
valve spool fully out (counter-clockwise) until it hits
the stop.
3. Check that the dual spool valve is set to the hydrau-
lic system type (open-center (OC) or closed-center
(CC) operation).
2. Insert the small plug from the kit (furnished with the
tool) into the hole located in the top of the selector
screw. Tap the plug down using a small punch and
hammer. DO NOT USE ANY ADHESIVES.
CHECK TOOL
TO DISABLE DUAL SPOOL OPERATION
1. Make sure all tool accessories are correctly in-
stalled. Failure to install tool accessories properly AND CONVERT TO CLOSED-CENTER
can result in damage to the tool or personal injury.
ONLY OPERATION
2. There should be no signs of leaks.
1. Turn the selector screw located in the top of the
valve spool fully in (clockwise) until it bottoms.
3. The tool should be clean, with all fittings and fasten-
ers tight.
2. Insert the small plug from the kit (furnished with the
tool) into the hole located in the top of the selector
screw. Tap the plug down using a small punch and
hammer. DO NOT USE ANY ADHESIVES.
CHECK TRIGGER MECHANISM
Check that the trigger operates smoothly and is free to
travel between the ON and OFF positions.
BLADE INSTALLATION
1. Handle the saw blade with care. The cutting edges
are sharp and careless handling could result in in-
jury.
SETTING THE DUAL SPOOL FOR OC
(OPEN-CENTER) OR CC (CLOSED-
CENTER) OPERATION
2. Install the blade over the motor shaft and onto the
fixed collar so that the points of the teeth on the
blade are facing clockwise as viewed from the front
of the motor (see Figure 2).
IMPORTANT
3. Install the moveable collar followed by the collet nut
(see Figure 3). Tighten the collet nut hard (not wrist
tight).
This tool is furnished with a ON/OFF spool
commonly referred to as a “dual spool” which permits
adjustment so the tool may be operated on either an
open-center (OC) or closed-center (CC) hydraulic
system. The dual spool is normally set to the OC
position at time of manufacture. The dual spool can
also be disabled so that the tool may be set to OC
only operation. For more details, please refer to the
following instructions.
4. Install the locking nut with internal taper facing to-
ward the collet nut and tighten it hard against the
collet nut.
5. As a final tightening procedure, with a wrench on
each of the nuts, tighten the locking nut one half
wrench flat further.

OPERATION
•
•
Always connect the hoses to the tool hose couplers
before energizing the power source.
CLOCKWISE ROTATION
Do not operate a circle saw that is damaged, im-
properly adjusted or is not completely and securely
assembled.
•
Keep the saw and handles clean and free of oil and
contaminates.
•
•
•
•
Do not hang the saw on utility wires or cables.
Do not leave the saw hanging in a tree.
Do not leave cut branches in a tree.
Branches bent under tension are considered haz-
ardous.
Figure 2. Correct Rotation Direction
•
•
Do not allow binding of the saw blade.
COLLET NUT
The saw blade will continue to spin for up to 5 sec-
onds or more after releasing the ON/OFF trigger.
During this “coast down” time, contact with the saw
blade may result in severe personal injury. Refer to
page 2. On early model saws the “coast down” time
will be up to 15 seconds.
LOCKING NUT
•
Use extreme caution when sawing small size brush
and saplings. Slender material may catch in the saw
blade and be thrown toward the operator.
Figure 3. Collet Nut & Locking Nut
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth
•
•
Keep the saw blade away from all surfaces when
starting rotation of the blade.
before making connections.
2. Connect the hoses from the hydraulic power source
to the hose couplers on the saw. It is a good prac-
tice to connect the return hose first and disconnect
it last to minimize or avoid trapped pressure within
the saw motor.
Do not reverse blade rotation direction by changing
oil flow direction. The saw is designed to operate in
only one direction.
•
•
Do not use the saw around energized transmission
lines.
3. Observe flow indicators stamped on hose couplers
to be sure that oil will flow in the proper direction.
The female coupler is the inlet coupler.
Do not inspect, clean or repair the saw with the pow-
er source operating or with operating pressure at the
saw. Accidental engagement of the tool can cause
serious injury.
NOTE:
The pressure increase in uncoupled hoses left in the
sun may result in making them difficult to connect.
When possible, connect the free ends of operating
hoses together.
•
•
Do not operate the saw at oil temperatures above
140 °F/60 °C. Operation at higher temperatures can
cause higher than normal temperatures at the tool
which can cause operator discomfort.
After releasing the ON/OFF trigger, be certain that
the saw blade has come to a complete stop before
placing the saw on the ground, lowering the saw into
the truck’s bucket, storing the saw or contacting the
blade in any way. Failure to observe these precau-
tions may result in severe personal injury.
OPERATING PROCEDURES
Observe all safety precautions.
•
DO NOT OPERATE A CIRCLE SAW UNLESS YOU
HAVE BEEN SPECIFICALLY TRAINED TO DO
SO.
•
•
Keep all parts of the body away from the saw blade
during operation of the tool.
•
The saw operator must keep other workers and by-
standers clear of the work area, including the area
into which cut limbs or debris fall. Failure to heed
this precaution can result in severe personal injury.
Carry the saw with the unit de-energized and the
blade away from the body.

OPERATION
4. In sawing limbs which have a tendency to split or
tear when making a single saw flush cut, Figure 4, it
is advisable to make more than one cut. The first cut
is made a few inches from the point of the flush cut
removing the weight of the limb being trimmed out
and leaving a short stub. The stub is then flushed off
as shown in Figure 5. Whenever practical, the cut
shall be treated with tree paint if it is larger than 1
inch in diameter. This technique will avoid breaking
the lateral which you are trying to save or splitting
the remaining limb down the center as the flush cut
is made.
MAKING CUTS
WARNING
The following are general wood cutting procedures
and techniques. Differences in the terrain,
vegetation, and type of wood will make this
information more or less valid for particular areas.
For advice on specific wood cutting problems or
techniques for your area, consult your local Stanley
representative or your county agent. They can often
provide information that will make your work safer
and more productive.
1. Move the hydraulic circuit control valve to the ON
position to pressurize the circuit.
2. Maintain a firm grip on the saw handle. While main-
taining firm footing and balance, position the saw
blade near the material to be cut.
FINAL CUT
3. Squeeze the ON/OFF valve handle trigger and allow
the saw blade to reach FULL speed.
THE FIRST CUT IS TO TAKE WEIGHT
OFF BEFORE THE FINAL CUT TO
PREVENT THE LIMB FROM SPLITTING
DOWN THE CENTER.
IMPORTANT
Figure 5. Flush Cut
The saw blade must reach FULL speed before
attempting a cut.
WARNING
LATERAL BRANCH
Do not cut material that is directly overhead. When it
falls it may cause operator injury.
5. Watch the saw reaction to making a cut. Control the

WARNING
Figure 4. Flush Cutting a Limb That Might Split or Tear.
After releasing the ON/OFF trigger, saw operators
must be certain that the saw has come to a complete
stop after a few seconds or more. The saw blade
must come to a complete stop before placing the saw
into the truck’s bucket, storing the saw or contacting
the blade in any way. Failure to observe this warning
may result in severe personal injury.

OPERATION
Maintain a 20° angle and always file outwards on each
right or left cutter tooth. File only with a slight pressure
against the cutter tooth (not on top of the cutter) during
the forward stroke. Release pressure as you pull the file
back. The file will only cut during the forward stroke.
AFTER OPERATION
1. Wipe the saw thoroughly with a clean dry or slightly
oiled cloth.
2. Clean tree pitch and residue from the blade. Handle
the blade with care to avoid getting cut by the sharp
teeth.
While filing, always try to keep the file holder perpen-
dicular to the side of the blade. Try not to move the file
holder up or down or move the file holder to the setting
of the tooth.
3. Check all fasteners for tightness.
4. When the saw is not in use, store horizontally in a
clean, dry space and protected from damage.
5. Protect the blade teeth and keep the teeth sharp. A
sharp blade will cut cleaner and faster.
BLADE CARE
Every day visually check the blade for cracks and warp-
age. Cracks will lead to a break and “out of flat” will
cause excessive vibration. Make sure the spindle lock-
nut is tight.
When sharpening, never use a flat file which may leave
a square corner in the gullet. Because of high speed
vibration, this becomes a point from which a crack will
start.
Figure 7. Filing Angle
TOP OF CUTTERS
Do not let gum, sap or dirt build up underneath the cut-
ting edges. This adds undue friction and reduces cutting
efficiency due to loss of clearance.
The top of each cutter is factory ground to ensure the
best cutting performance. Normally, the tops of the cut-
ters will not require filing unless the edge is badly worn
or damaged.
Inspection of the cutting teeth should be made often dur-
ing each day’s use. It is faster to touch up the teeth with
a few strokes of the file than to allow the teeth to get dull.
Dull teeth cause loss of cutting capacity and too much
friction. A sharp spare blade is a good back-up in case
of trouble.
If the top of a cutter requires filing, use a smooth flat file
to give the cutter its original shape. After filing, ensure
that all cutters have the same length and profile.
SETTING TOOTH ANGLE
BLADE SHARPENING
BLADE TEETH
A sharp outside corner and an exact angle setting will
give maximum cutting performance. Special setting tool
(Stanley part number 34653) is required to verify or prop-
erly set the angle of each cutter tooth at .040 inch/1 mm.
Using a file holder with a 7/16 inch round file (Stanley
Part Number 11299), place the file holder flat on top of
the cutter with the file against the cutter tooth.
Match one of the grooves in the setting tool to the blade
thickness. Place the setting tool over the cutter near the
cutter tooth and bend the tooth until the angle on the set-
ting tool touches the side of the blade. DO NOT OVER
SET. Over-setting will cause rough cutting and vibration
which may result in stress cracks and eventual blade
failure.

COLD WEATHER OPERATION
If the saw is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluids, fluid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) be-
fore use.

TOOL PROTECTION & CARE
NOTICE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
•
•
Make sure all couplers are wiped clean before con-
nection.
•
Do not exceed the rated flow and pressure. Refer
to the Specifications page in this manual for correct
flow and pressure rates. If flow and pressure are ex-
ceeded, rapid failure of the internal seals may result.
The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydrau-
lic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hy-
draulic system.
•
•
•
•
Always keep critical tool markings, such as warning
stickers and tags legible.
Tool repair should be performed by experienced
personnel only.
•
•
Always store the tool in a clean dry space, safe from
damage or pilferage.
Make certain that the recommended relief valves
are installed in the pressure side of the system.
Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse cir-
cuit flow. This can cause damage to internal seals.
Do not use the tool for applications for which it was
not intended.
•
Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a mini-
mum working pressure rating of 2500 psi/172 bar.
