cautions relating to the specic work area and local
safety regulations. If so, place the added precautions in
the space provided in this manual.
The CS25/28 Hydraulic Pole Chain 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.
• 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 dangerous terrain conditions.
• Establish a training program for all operators to en-
sure safe operation.
• 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.
• Do not overreach. Maintain proper footing and bal-
ance at all times.
• Do not inspect or clean the tool while the hydraulic
power source is connected. Accidental engagement
of the tool can cause serious injury.
• Supply hoses must have a minimum working pressure rating of 2500 psi/175 bar.
• Be sure all hose connections are tight.
• 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 damage to the quick couplers and cause overheating of
the hydraulic system.
• 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.
• Do not operate a damaged, improperly adjusted, or
incompletely assembled tool.
• To avoid personal injury or equipment damage, all
tool repair, maintenance and service must only be
performed by authorized and properly trained personnel.
• 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.
• Always replace parts with replacement parts recommended by Stanley Hydraulic Tools.
• Check fastener tightness often and before each use
daily.
• Do not wear loose tting clothing when operating the
tool.

SAFETY PRECAUTIONS
POLE CHAIN SAW SPECIFIC
SAFETY PRECAUTIONS
• Do not rely exclusively upon the safety devices built
into the saw. As a pole saw user, several steps must
be taken to keep your cutting jobs free from accident
or injury.
• With basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
• Keep a good rm grip on the pole chain saw with
both hands. Place your right hand on the rear handle and your left hand on the outer tube assembly
when operating. Use a rm grip with your thumbs
and ngers encircling the chain saw handle and outer tube assembly. A rm grip helps reduce kickback
and maintains control of the pole chain saw. Do not
let go.
• Make sure the area in which you are cutting is free
of obstructions. Never allow the nose of the guide
bar to contact a branch or any other obstruction that
can be accidently hit while operating the saw.
• Cut at the rated operating speeds (gpm).
• Follow the manufacturer’s sharpening and mainte-
nance instructions for the saw chain.
• Only use replacement bars and chains specied by
Stanley or equivalent.
• Make sure you’re well rested and mentally alert before operating the pole chain saw.
• Do not start cutting until you have a clear work area,
secure footing and a planned drop area for falling
branches.
• Keep all parts of the body away from the saw chain
during operation.
• Carry the saw with the unit de-energized.
• Do not operate a pole chain saw that is damaged,
improperly adjusted or not completely and securely
assembled. Make sure the chain stops moving when
the control trigger is released.
• Use extreme caution when cutting small branches.
Twigs may catch the saw chain and be whipped toward the operator or pull the operator off balance.
• When cutting a limb that is under tension, be aware
of spring back so you will not be struck when the
tension on the limb is released. Always cut on the
outside arc or curve.
• Keep the handle dry, clean and free of hydraulic
uid.
• When using tools near energized transmission lines,
make sure to use only hoses labeled and certied
non-conductive.
• Turn off the power unit or move the hydraulic control
valve to neutral before setting the pole chain saw
down.
• Use a chain bar scabbard when transporting the
saw.
• Know the location of buried or covered electrical
services before starting work.
• To avoid personal injury or equipment damage, all
tool repair, maintenance and service must only be
performed by authorized and properly trained personnel.

OPERATION
PRE-OPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated owmeter and pressure gauge,
make sure the hydraulic power source develops a
ow of 4-6 gpm /15-22 lpm at 1500-2000 psi/105/140
bar for the CS25 or a ow of 7-9 gpm/26-34 lpm at
1000-2000 psi/70-140 bar for the CS28.
2. Make sure the power source is equipped with a relief valve set to open at 2100-2250 psi/145-155 bar.
3. Check that the dual spool valve is set to the hydraulic system type (open-center (CC) or closed-center
(CC) operation).
CHECK TOOL
1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly
can result in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all ttings and fasten-
ers tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the ON and OFF positions.
SETTING THE DUAL SPOOL FOR
OPERATION
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
a open-center hydraulic system or a closed-center
hydraulic system. The dual spool is normally
set to the open-center (OC) position at time of
manufacture. The dual spool can also be disabled
so that the tool may be set to open-center only
operation or closed-center only operation. For more
details, please refer to the following instructions.
screw located in the top of the valve spool fully in (clockwise) until it bottoms.
TO DISABLE DUAL SPOOL OPERATION
AND CONVERT TO OC ONLY OPERATION
Turn the selector screw located in the top of the valve
spool fully out (counter-clockwise) until it hits the stop.
1. 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.
TO DISABLE DUAL SPOOL OPERATION
AND CONVERT TO CC ONLY OPERATION
1. Turn the selector screw located in the top of the
valve spool fully in (clockwise) until it bottoms.
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.
CONNECTING HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the tool ttings or quick disconnects. It is a good
practice to connect return hoses rst and discon-
nect them last to minimize or avoid trapped pressure
within the tool.
3. Observe the arrow on the couplers to ensure that
the ow is in the proper direction. The female coupler on the tool is the inlet (pressure) coupler.
4. Move the hydraulic circuit control valve to the ON
position to operate the tool.
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hoses can make them difcult to
connect. If possible, connect the free ends of the
hoses together.
SETTING FOR OPEN-CENTER (OC) OR
CLOSED-CENTER (CC) OPERATION
To set the tool for OC system operation turn the selector screw located in the top of the valve spool fully out
(counter-clockwise) until it hits the stop.
To set the tool for CC system operation turn the selector

WARNING
WARNING
The following are general woodcutting 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 specic
wood cutting problems or techniques for your area,
consult you local Stanley representative or your
county agent. They can often provide information
that will make your work safer and more productive.
CUTTING TIPS
1. Check the lean of the tree. Tie a weight to a piece
of string about 2 feet long. Hang the weight in your
line of sight. The string is a good vertical line to help
you judge the lean of a tree. The tree should fall
the way the string is leaning. Trees that are straight
(leaning no more than 5°) generally can be felled in
any direction.
2. Check the weight distribution. A tree is heavier on
the side with the most limbs. It will try to fall on its
heavy side. Trim a few limbs to balance the tree.
3. Clear the work area. You need a clean area all
around the tree. Get everything out of the area where
the limbs might fall. Do not cut trees near structures.
Because of the danger of electrocu tion, use extreme
care when cutting trees near power lines.
4. The chain saw should cut with very little pressure
applied to the handle. If you have to force the cut or
if the cut is not straight, cease cutting immediately
to prevent further saw chain and bar damage. See
the MAINTENANCE AND ADJUSTMENTS section
in this manual for chain replacement, sharpening or
adjustment proce dures.
Watch for falling limbs.
4.
Make a diagonal cut down to meet the horizontal cut
and remove the wood from the notch.
FELLING OR BACK CUT
5. The felling or back cut is made on the side opposite
and at least 2 inches above the horizontal undercut
(the felling cut is made higher as the size of the tree
increases).
6. Start the cut horizontally parallel to the notch cut.
Cut until the saw is about 1 or 2 inches from the
notch. DO NOT CUT THROUGH THE NOTCH.
NOTE:
The uncut wood between the felling and notch cuts
is called the hinge. The hinge controls the fall of the
tree and should be of uniform thickness.
7. As the saw nears the back cut, watch the tree-top
and the cut for signs of movement. Be alert as soon
as the tree starts to move, turn off the saw, pull it
from the tree and move away quickly on your escape route.
FELLING OR TOPPING
1. Observe safety precautions.
NOTCHING OR UNDERCUTTING
2. The notching or undercutting cut is made on the side
you want the tree to fall.
3. Start the cut horizontally. Cut to about one-quarter of
the tree’s diameter.
14 ► CS25/28 User Manual
Figure 2. Felling a Tree
LOGS/LIMBS WITH PRESSURE ON
BOTTOM
1. Observe all safety precautions.
2. Begin with a bottom-cut. The depth of the cut should
be about one-third of the log diameter.
3. Finish with an upper cut, down from the top. The
saw cuts should meet.
OPERATION
PRUNING & TRIMMING
1. Observe all safety precautions.
2. Use both hands. Keep a rm grip.
3. Be alert for kickback. Do not allow the tip of the bar
to touch anything while the chain is in motion.
Figure 3. Crosscutting Logs/Limbs with
Pressure on Bottom
4. Pole chain saws must be hung securely in a vertical
position to prevent dislodgement. Pole chain saws
must not be hung on utility wires or cables and must
not be left in the tree overnight. Pole chain saws
must be hung so the sharp edge is away from the
worker, if possible.
5. Warnings, when necessary, must be given by the
worker in the tree before a limb is dropped. “Timber” or “heads up” are common terms used for this
purpose.
6. A separate line should be attached to limbs that cannot be dropped safely or are too heavy to be controlled by hand. The line should be held by workers on the ground end of the rope. Use of the same
crotch for both the safety rope and the work rope
should be avoided.
7. The safety line or climbing rope must not be used for
any purpose but for climbing.
8. Cut branches must not be left in trees overnight.
TOPPING/LOWERING LIMBS
1. Observe all safety precautions.
2. Use both hands. Keep a rm grip.
3. Workers performing topping operations should
make sure the trees are able to stand the strain of
a topping procedure. If not, some other means of
lowering the branches should be provided, such as
a tree crane.
4. If large limbs are lowered in sections, the worker in
the tree should be above the limb being lowered.
5. Guidelines, hand lines, or tag lines must be used
when conditions warrant their use.
LIMBING AND BUCKING
1. Observe all safety precautions.
2. Use both hands. Keep a rm grip.
3. When it is possible to do so, the tree worker must
work on the side opposite the side on which the limb
is being cut.
4. Branches bent under tension must be considered
hazardous.
COLD WEATHER OPERATION
If the pole chain saw is to be used during cold weather,
preheat the hydraulic uid at low engine speed. When
using the normally recommended uids, uid should be
at or above 50 °F/10 °C (400 ssu/82 centistokes) before
use.
Damage to the hydraulic system or pole chain saw can
result from use with uid that is too viscous or thick.
Cutting frozen wood causes the cutters to wear, crack
and break at the back rivet hole unless proper precautions are taken. To extend chain life when cutting in cold
weather:
• Be sure the automatic oiler is working.
• Keep the chain tensioned and check often.
• Keep the chain properly sharpened. Touch up at
least every hour. Never force a dull chain to cut.
• Clean out the bar groove and keep the oil hole open.
Turn the bar over to equalize wear on the rails.
• Always install a new sprocket with a new chain.
CS25/28 User Manual ◄ 15
OPERATION
AUTOMATIC OILER ADJUSTMENT
1. Observe all safety precautions.
2. The automatic oiler is located in the front of the motor housing. The oil volume can be adjusted with a
3/16 inch Allen wrench by turning the plug counterclockwise to increase output and turning clock wise
to decrease output.
NOTE:
Oil output varies proportionally to load and operat-
ing pressure. It should be adequate for most operations as adjusted from the factory.
3. Initial oiler adjustment is made with the saw bar and
chain removed.
The following step can be hazard ous. Failure to
heed the instructions could result in serious injury.
4. Connect the pole chain saw to a hydraulic power
source and check for proper operation. READ THE
FOLLOWING CAREFULLY BEFORE PROCEEDING.
a. Make sure the hydraulic power source is run-
ning at the lowest gpm/lpm rate it can while still
producing full pressure.
b. Secure the pole chain saw rmly in a bench vise
and place the correct size wrench on the 1/2-20
nut securing the sprocket.
c. Connect the hydraulic power source to the pole
chain saw and turn the circuit control valve to
the ON position.
d. With a rm grip on the pole chain saw and
wrench, SLOWLY squeeze the trigger to activate it.
e. Adjust the oiler for a ow of approximately one
drop every one to two seconds.
f. Release the trigger and remove the wrench.
CHAIN TENSION ADJUSTMENT
1. Observe all safety precautions.
2. When the chain appears loose, lubricate it well and
let it cool for a few minutes to allow for contraction
of the chain. Disconnect the pole chain saw from its
hydraulic power source.
NOTE:
Perform Steps 3 through 6 while holding the top end
of the saw bar upward.
3. Loosen the two saw bar nuts slightly.
4. Tighten the chain tension screw until the bot toms of
the tie straps and cutters just touch the saw bar rails
of the bottom of the saw bar.
5. Pull the chain around the saw bar by hand to be sure
it ts the sprocket and saw bar properly. The chain
should move easily.
6. Hold the saw bar tip up as you tighten the two saw
bar nuts.
7. Connect the pole chain saw to a hydraulic power
source. Operate the chain at low speed (gpm) for a
minute or two while pumping extra oil on the chain.
8. Stop the pole chain saw and check the tension.
If it has loosened, disconnect the pole chain saw
from the hydraulic power source and perform Steps
3 through 6 again to tighten the chain to the correct
tension.
9. Reconnect the pole chain saw to the hydraulic power source. Operate the saw and make a few easy
cuts. Check chain tension and readjust if necessary
(disconnect it from the hydraulic power source and
perform Steps 3 through 6).
NOTE:
Never break in a new chain under a heavy cutting
load.
10. Watch the chain tension carefully for the rst half-
hour of cutting.

NOTICE
TOOL PROTECTION & CARE
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 connection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydraulic
tools. Failure to do so may result in damage to the
quick couples and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• 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 ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
this manual for correct ow rate and model number.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Do not use the tool for applications it was not designed for. The chain saw is intended to cut wood
only.
• Keep chain sharp for maximum tool performance.
• Tool repair should be performed by experienced
personnel only.
• Make certain that the recommended relief valves
are installed in the pressure side of the system.
• Do not use the tool for applications for which it was
not intended.
