SAFETY SYMBOLS

CS11 Service Manual ◄ 5
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.
These precautions are given for your safety. Review
them carefully before operating the tool or performing
maintenance.
Supervising personnel should develop additional
precautions relating to the specic work area and local
safety regulations. Place the added precautions in the
space provided in this manual.
The CS11 Hydraulic 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 hose before operation. Failure to do so could
result in personal injury or equipment damage.
• Operators must start in a work area without
bystanders. Flying debris can cause serious injury.
• Do not operate the tool unless trained or under the
supervision of an instructor. Establish a training
program for all operators to ensure safe operation.
• Always wear safety equipment such as goggles, ear
and head protection, and safety shoes at all times
when operating the tool. Use gloves and aprons
when necessary.
• Operators must be familiar with all prohibited work
areas such as excessive slopes and dangerous
terrain conditions.
• Do not inspect, clean or replace parts if the hydraulic
power source is connected. Accidental engagement
of the tool can cause serious injury.
• Always connect hoses to the tool hose couplers
before energizing the hydraulic power source. Be
sure all hose connections are tight and are in good
condition.
• Do not operate the tool at oil temperatures above
140 °F/60 °C. High oil temperatures can cause high
temperature at the tool, which can result in operator
discomfort.
• Do not operate a damaged, improperly adjusted or
incompletely assembled chain saw. Be sure that the
chain stops moving when the trigger is released.
• Never wear loose clothing that can become
entangled in the working parts of the tool.
• Keep all parts of your body away from the chain saw
and maintain proper footing and balance at all times.
• Do not rely exclusively upon safety devices built into
the saw. As a chain saw user, steps must be taken to
keep your cutting jobs free from accidents or injury.
• With basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
• To avoid personal injury or equipment damage,
all tool repair, maintenance and service must be
performed by authorized and trained personnel.
• Keep a rm grip on the saw, with both hands, when
operating the saw. The right hand on the rear handle
and the left hand on the front handle. Use a rm grip
with thumbs and ngers encircling the chain saw
handles. A rm grip will help reduce kickback and
maintain control of the 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 the log, branch or any obstruction that
can be accidently hit while operating the saw.
• WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• Lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to lter out microscopic particles.
Protect yourself and those around you. Research
and understand the materials you are cutting.
Follow correct safety procedures and comply with
all applicable national, state or provisional health
and safety regulations relating to them, including,
if appropriate arranging for the safe disposal of the
materials by a qualied person.
• Never start the tool while it is lying on the ground.
• Cut at rated operating speeds (GPM).
SAFETY PRECAUTIONS

6 ► CS11 Service Manual
• Do not overreach or cut above shoulder height.
• Follow manufacturer’s sharpening and maintenance
instructions for the saw chain.
• Only use bars and chains specied by STANLEY.
Chains must meet the requirements of ANSI B175.1
for low kickback performance.
• Always be well rested and mentally alert before
operating the chain saw.
• Do not allow other persons to be near the chain saw
when starting or cutting with the chain saw. Keep
bystanders and animals out of the work area.
• Do not start cut until you have a clear work area,
secure footing and a planned escape path from a
falling tree.
• Carry the saw with the unit de-energized and the bar
and chain to the rear of your body.
• Use extreme caution when cutting small size brush
and saplings. Twigs may catch the saw chain and
be whipped toward the operator or pull the operator
o󰀨 balance.
• When cutting a limb that is under tension, be alert
for spring-back so that you will not be struck when
the tension on the limb is released.
• Keep the handles dry, clean and free of oil.
• Do not operate a chain saw while in a tree unless
you have been specially trained to do so.
• When using tools near energized transmission lines,
be sure to use only hoses labeled and certied non-
conductive.
• Turn o󰀨 the power unit before setting the saw down.
• Use a guide bar scabbard when transporting the
saw.
• Know the location of buried or covered electrical
services before starting work.
• The spiked bumper (bucking cleat) must be installed
for felling operations.

CS11 Service Manual ◄ 13
PREPARATION PROCEDURES
HYDRAULIC SYSTEM REQUIREMENTS
The hydraulic system should provide a ow of 10-14
GPM/38-53 LPM at an operating pressure of 1500-2000
psi/105-140 bar. Recommended relief valve settings are
2100-2250 psi/145-155 bar.
The system should have no more than 250 psi/17 bar
backpressure measured at the tool end of the operating
hoses. The system conditions for measurement are
at maximum uid viscosity of 400 ssu/82 centistokes
(minimum operating tem peratures).
The hydraulic system should have su󰀩cient heat
rejection capacity to limit the maximum oil temperature
to 140° F/60° C at the maximum ex pected ambient
temperature. The recommended minimum cooling
capacity is 7 hp/5.22 kW at a 40 °F/22 °C di󰀨erence
between ambient temperature and oil temperature.
The hydraulic system should have a minimum of 25
micron ltration. It is recommended that lter elements
be sized for a ow of at least 30 GPM/114 LPM for cold
temperature startup and maximum dirt holding capacity.
The hydraulic uid used should have a vis cosity between
100 and 400 ssu/20 and 82 cen tistokes at the maximum
and minimum expected operating temperatures.
Petroleum based hydraulic uids with antiwear properties
and a viscosity index over 140 ssu/28 centistokes will
meet the recom mended requirements over a wide range
of operating temperatures.
The recommended hose size is .625-inch/16 mm I.D. up
to 50 ft/15 m long and .750-inch/20 mm I.D. minimum up
to 100 ft/30 m long.
CHECK POWER SOURCE
1. Using a calibrated ow meter and pressure gauge,
check that the hydraulic power source develops
a ow of 10-14 GPM/38-53 LPM at 1500 -2000
psi/105-140 bar.
2. Make certain that the hydraulic power source is
equipped with a relief valve set to open at 2100 -
2250 psi/145-155 bar.
CONNECT 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. Connect return hoses rst and
disconnect them last to minimize 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 hose 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
increase inside the hose may make them di󰀩cult to
connect. Whenever possible, connect the free ends
of the hoses together.
OPERATING PROCEDURES
The following are general wood cut ting procedures and
techniques. Di󰀨 erences in the terrain, vegetation and
type of wood will make this infor mation more or less valid
for particu lar areas. For advice on specic woodcutting
problems or techniques for your area, consult your local
STANLEY representative or your county agent. They
can often provide infor mation 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 the tree. The tree should fall
the way it is leaning. Trees that are straight (leaning
no more than 5 degrees) gener ally can be felled in
any direction.
2. Avoid felling across another tree, log, rocks, gully or
ridge. Do not fell straight uphill or down hill. Fell the
tree diagonally to the hill. Consider the wind direction
and velocity. Do not attempt cutting in strong winds.
3. 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.
4. Clear the work area. You need a clean area all
around the tree for good footing. Get every thing
out of the area where the tree will fall. Do not cut
trees near structures. Because of the danger of
electrocution, use extreme care when cutting trees
near power lines.
5. Before starting the cut, prepare your escape path.
Make sure the escape path is clear of brush and
branches. The escape path should be at an angle
away from the direction of fall.
6. The saw chain should cut with very little pres sure
applied to the handle. If you have to force the saw
to 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 of this manual for chain replacement or
adjustment procedures.
7. Underwater models require daily preventive
maintenance.
OPERATION

14 ► CS11 Service Manual
FELLING
(CUTTING DOWN A TREE) (FIGURE 2)
Observe all safety precautions. The spiked bumper
(bucking cleat) must be installed for this operation.
Figure 2. Felling a Tree
NOTCHING OR UNDERCUTTING
1. The notching or undercutting cut is made on the side
you want the tree to fall. Place the saw so the hand
guard is close to the tree trunk and the bucking cleat
is dug in.
2. Start the cut horizontally. Pivot the nose of the bar in
last. Cut to about one-quarter of the tree’s diameter.
3. Watch out for falling limbs.
4. Make a diagonal cut down to meet the hori zontal 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). Place the saw so the hand guard is close
to the tree trunk and the bucking cleat is dug in.
6. Start the cut horizontally. Pivot the bar in until the cut
is being made 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 thick ness.
7. As the saw nears the back cut, watch the treetop
and the cut for signs of movement. Be alert as
soon as the tree starts to move, turn o󰀨 the saw,
pull it from the tree and move away quickly on your
escape route.
8. For trees larger than bar length, make two felling
cuts. Cut in as far as the bar will go, move to the other
side and start the second cut in the same manner as
the rst while pivoting the saw to complete the felling
cut.
BUCKING
Bucking is the sawing of a log or fallen tree into smaller
pieces.
1. Observe all safety precautions.
2. Use both hands. Grip the saw rmly.
3. Stand uphill. A log that is cut loose may roll downhill.
4. Keep the chain out of the dirt. Dirt will dull the chain.
A dull chain is unsafe.
5. Stand to the left of the saw.
CROSSCUTTING
Note: Before starting to cut through a log try to
imagine what is going to happen. Look out for
stresses in the log and cut through the log in such a
manner that the guide bar will not get pinched.
LOGS WITH PRESSURE ON TOP
(FIGURE 3)
6. Observe all safety precautions.
7. Begin with an upper cut, down from the top. Do not
cut too deeply. A cut of about 1/3 of the log diameter
is enough.
8. Finish with a bottom cut. They should meet.

1. Observe all safety precautions.
2. Begin by cutting on the opposite side of the log.
3. Pull the saw towards you and cut from the top.
4. Cut from the bottom. Make a boring cut if the log is
close to the ground.
5. Finish with a bottom cut.

5. Finish with a top cut.
PRUNING AND DEBRANCHING
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.
4. Do not cut overhead. Keep the saw below chest
level. The chain is too close to your face in this
position.

COLD WEATHER OPERATION
If the saw is to used during cold weather, preheat the
hydraulic uid at low engine speed. When using the
normally recommended oils, oil should be at or above
50 °F/10 °C (400 ssu/ 82 centistokes) before use.
Damage to the hydraulic system or 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:
5. Be sure the oiler is working.
6. Keep the chain tensioned and check often.
7. Keep the cutters properly sharpened. Touch up at
least every hour. Never force a dull chain to cut.
8. Clean out the bar groove and keep the oil hole open.
Turn the bar over to equalize wear on the rails.
9. Always install a new sprocket with a new chain.
UNDERWATER MODEL
MAINTENANCE
After each use, the movable portions of the tool that
were exposed to water should be ushed with a water
displacing oil, such as WD40™. Remove water and
debris as follows:
1. Spray oil through the tool and displace any remaining
water.
2. Spray oil into the On/O󰀨 trigger slot area
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before
storing away.
OPERATION

CS11 Service Manual ◄ 17
• 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 couplers 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
circuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by STANLEY.
Supply hoses must have a minimum working
pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow and pressure.
Rapid failure of the internal seals may result. See
“SPECIFICATIONS” on page 19 for correct ow
rate and pressure rating.
• Always keep critical tool markings, such as warning
stickers and tags, legible.
• 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.
In addition to the safety precautions found in
this manual, observe the following for equipment
protection and care.
TOOL PROTECTION & CARE

18 ► CS11 Service Manual
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 ow and pressure to the saw as listed in the table. Use a ow meter know to be accurate. Check the ow
with the hydraulic uid temperature at least 80 °F/27 °C.
PROBLEM CAUSE REMEDY
