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  
tool and hoses before operation. Failure to do so could  
result in personal injury or equipment damage.  
Always replace parts with replacement parts recom-  
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.  
Always wear safety equipment such as goggles,  
ear, head protection, and safety shoes at all times  
when operating the tool.  
Never cock, jam or wedge the saw blade during op-  
eration.  
Eye injury and cutting or severing of body parts is  
possible if proper procedures are not followed.  
Do not overreach. Maintain proper footing and bal-  
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.  
Do not operate a damaged, improperly adjusted, or  
incompletely assembled tool.

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.

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.  
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be  
obtained from your Stanley Distributor.

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.

TROUBLESHOOTING  
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When  
diagnosing faults in operation of the saw, always make sure the hydraulic power source is supplying the correct  
hydraulic flow and pressure to the saw as listed in the table. Use a flowmeter know to be accurate. Check the flow  
with the hydraulic fluid temperature at least 80 °F/27 °C.
