Cub Cadet PS59L Operator's Manual
READ ALL INSTRUCTIONS BEFORE OPERATING
SAFETY BASICS
• Carefully read and understand the operator's manual of the battery that powers this unit.
• Be thoroughly familiar with the controls and the proper use of the unit. Know how to stop the unit and
disengage the controls quickly.
• Stay alert! Do not operate the unit when tired, ill or under the influence of alcohol, drugs or medication.
• Never allow children to operate the unit. Never allow adults to operate the unit without proper instruction.
• Do not allow the unit to be used as a toy.
• Make sure that all guards and safety attachments are properly installed before operating the unit.
• Keep these instructions. Refer to them often and use them to instruct other users. If loaning someone this
unit, also loan them these instructions.
PRELIMINARY SAFETY PRECAUTIONS
• DO NOT rely exclusively upon the safety devices built into the unit.
• Keep bystanders, especially children and pets, at least 50 feet (15 m) away. If anyone enters the
work area, stop the unit!
• Keep the work area clean. Cluttered areas invite injuries. Do not start cutting until the work area is clear
and free from obstructions, there is secure footing and a planned retreat path from falling branches.
• Always wear appropriate eye and ear protection when operating this unit. Wear safety goggles, or
safety glasses with side shields, that are marked as meeting ANSI Z87.1-1989 standards. Failure to
do so could result in serious eye injury caused by thrown or falling objects. If the operation is dusty,
wear a face mask or dust mask. When operating the unit over the head, use a hardhat or other type
of safety helmet.
• Dress appropriately, wear heavy, snug-fitting clothes (long pants and a long sleeve shirt), non-slip
protective gloves and steel-toed safety boots. Do not wear loose clothing, jewelry, short pants,
sandals or go barefoot. Secure hair above shoulder level to prevent entanglement in moving parts.
• Only use the unit in daylight or good artificial light.
• Only use the unit for the purpose intended.
UNDERSTANDING KICKBACK
• Rotational Kickback can happen when the upper tip of
the guide bar contacts an object while the chain is
moving (Fig. 1 & 2). This can cause the chain to dig into
the object and momentarily stop moving. The guide bar
is then kicked up and back toward the operator in a
lightning-fast reverse reaction.
• Pinch Kickback can happen when the wood on either
side of a cut closes in and pinches the moving saw chain
along the top of the guide bar. This can cause the chain
to instantly stop. The chain force is then reversed,
causing the saw to move in the opposite direction,
sending the saw straight back toward the operator.
• Pull-In can happen when the moving chain on the
bottom of the guide bar hits a foreign object inside
the wood. This can cause the chain to suddenly stop.
The saw is then pulled forward and away from the
operator, which could potentially result in the loss of
control of the saw.
KICKBACK SAFETY PRECAUTIONS
• DO NOT over reach.
• DO NOT make cuts with the tip of the guide bar.
• DO NOT let the tip of the guide bar contact any object,
such as a log, branch, ground or other obstruction.
Remove or avoid any obstructions that might impact the
tip of the guide bar while cutting.
• DO NOT cut more than one branch at a time.
• DO NOT twist the saw when removing the guide bar from an undercut.
• Never start the saw when the guide bar is inside an existing cut. Be extremely careful when re-entering
a cut.
• Grip the unit firmly with both hands when the motor is running. Keep the right hand on the handle and the
left hand on the pole shaft at a position that provides adequate support. Use a firm grip with thumbs and
fingers encircling the handle and pole shaft. Stand slightly to the left of the unit to avoid being in the direct
line of the saw chain. Follow all instructions in the Operating Instructions section.
• Keep proper footing and balance at all times.
• When starting the unit, always allow the motor to achieve full speed before beginning a cut. Fully squeeze
the switch trigger and maintain a steady cutting speed. Slower speeds increase the chance of kickback.
Keep the saw housing pressed firmly against the wood.
• Watch for shifting logs, branches, or other objects that might pinch, or fall onto, the chain while cutting.

• IMPORTANT SAFETY INSTRUCTIONS •
WARNING:Please read the entire operator’s manual carefully before
attempting to assemble, operate or maintain the unit. Follow all safety instructions. Failure
to do so can result in property damage or serious injury to yourself and/or others.
DANGER:
Kickback may occur when the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches the saw chain in the cut. In some cases, tip contact
may cause a lightening-fast reverse action, kicking the guide bar rapidly back towards the operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards
the operator. Either of these reactions may cause a loss of control over the saw, which could result in
serious injury to the user. Contact with foreign objects within the wood can also induce a loss of chain
saw control.

OPERATING INSTRUCTIONS
STARTING AND STOPPING INSTRUCTIONS
STARTING THE MOTOR
To help prevent accidental start-ups, this unit has a lock-off button and a switch
trigger that must be used together to start the unit.
1. Fit the battery into the handle cavity (Fig. 5). Refer to Installing the Battery.
2. Place your thumb on the lock-off button and push it completely in (Fig. 7).
3. While holding the lock-off button in, press and hold the switch trigger.
4. Release the lock-off button and continue to squeeze the switch trigger for
continued operation.
STOPPING THE MOTOR
1. Release the switch trigger.
NOTE: It is normal for the chain to coast to a stop once the switch trigger is released.
NOTE: Upon release of the switch trigger, the lock-off button will automatically reset
to the locked position.
PREPARATION FOR CUTTING
• To prevent electrocution, do not operate within 50 feet (15 m) of overhead
electrical lines (Fig. 8).
• Keep everyone – helpers, bystanders, children and animals – at least 50 feet
(15 m) away from the work area (Fig. 8). If anyone enters the work area, stop
the unit!
• Wear non-slip gloves for maximum grip and protection.
• Be certain the collars are fully tightened before operating the unit; check them
periodically for tightness during use to avoid serious injury.
• Maintain a proper grip on the unit whenever the motor is running. Hold the
unit firmly with both hands. Firmly grip the handle with the right hand and the
pole shaft with the left hand (Fig. 9).
• The operator should be to the left of the chain line. Never use a left-handed
(cross-handed) grip, or any stance that places any body part across the chain
line (Fig. 9).
• Never stand directly under the limb being cut.
PRUNING
This unit is designed for trimming small branches and limbs up to 6 inches (15.2 cm)
in diameter. For best results, observe the following precautions.
• Do not use the pole saw for cutting down trees.
• Plan the cut carefully. Be aware of the direction in which the branch will fall.
• Branches may fall in unexpected directions. Do not stand directly under the
branch being cut (Fig. 9).
• The most typical cutting application is to position the unit at an angle of 60°
or less, depending on the specific situation (Fig. 9). As the angle of the pole
saw shaft to the ground increases, the difficulty of making the first cut (from
the underside of the limb) increases.
• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more room to fall.
• Work slowly, keeping both hands on the unit with a firm grip. Maintain secure
footing and balance
• Do not cut from a ladder; this is extremely dangerous. Leave this operation for
professionals.
• Do not make the flush cut next to the main limb or trunk until the limb has
been cut further out to reduce the weight.
BASIC CUTTING PROCEDURE
Follow the steps below to prevent stripping the bark from the main member of the tree or shrub. Do not use a back-and-forth sawing motion.
1. Make a shallow first cut (1/4 of the limb’s diameter) on the underside of the limb close to the main limb or trunk (Fig. 10).
2. Make a second cut from the top side of the limb outboard from the first cut. Continue the cut through the limb until the limb separates
from the tree. Be prepared to balance the weight of the tool when the limb falls.
3. Make a final cut close to main limb or trunk.
NOTE: For second and final cuts (from the top of the limb or branch), hold the front cutting guide against the limb being cut (Fig. 11). This will
help steady the limb and make it easier to cut. Allow the chain to do the cutting; only exert light downward pressure. If the cut is forced,
damage to the bar, chain or motor may result.
4. Release the trigger as soon as the cut is completed. Failure to follow proper cutting procedures will result in the bar and chain binding
and becoming pinched or trapped in the limb. If this should happen:
• Stop the motor and remove the battery from the pole saw.
• If the limb can be reached from the ground, lift the limb while holding the saw. This should release the “pinch” and free the saw.
• If the saw is still trapped, call a professional for assistance.
WARNING:
If any parts are damaged or missing, do not
operate the unit until the parts are replaced. Failure to heed this
warning could result in serious personal injury.

dusty, wear a face mask or dust mask. When operating the unit
over the head, use a hardhat or other type of safety helmet.
Foam Grip
WARNING:
Use caution when pruning heavy branches.
Falling branches can cause serious injury. Always wear head
protection, plan a safe exit from the path of falling limbs and
stay alert.
WARNING:
Wear non-slip gloves for maximum grip and
protection. Refer to the Safety Information section for
appropriate safety equipment.
NO TOOLS REQUIRED!

CHAIN MAINTENANCE
For smooth and fast cutting, the chain needs to be maintained properly. The
following conditions indicate that the chain requires sharpening:
• Wood chips are small and powdery.
• The chain must be forced through the wood during cutting.
• The chain cuts to one side.
During maintenance of the chain, consider the following:
• The depth gauge (or raker clearance) setting determines the height at which the
cutter enters the wood and the size of the wood chip that is removed (Fig. 21).
Too much clearance increases the potential for kickback. Too little clearance
decreases the size of the wood chip, thus decreasing the chain's cutting ability.
• If the cutter teeth have hit hard objects, such as nails and stones, or were
abraded by mud or sand on the wood, have a service dealer sharpen the chain.
NOTE: Inspect the drive sprocket for wear or damage when replacing the chain.
If signs of wear or damage are present, do not use the unit.
NOTE: If you do not fully understand the correct procedure for sharpening the
cutters after reading the instructions that follow, have the saw chain
sharpened by an authorized service center or replace the chain with a
recommended low-kickback chain.
SHARPENING THE CUTTERS
Be careful to file all cutters to the specified angles and to the same length. Fast
cutting can be obtained only when all cutters are uniform.
• Tighten the chain tension enough so that the chain does not wobble. Do all of
the filing at the midpoint of the guide bar. Wear gloves for protection.
• Use a round file and holder.
• Keep the file level with the top plate of the tooth (Fig. 22). Do not let the file
dip or rock.
• Using light but firm pressure, stroke towards the front corner of the tooth (Fig. 23).
Lift the file away from the cutter before returning the file to the beginning of the
sharpening stroke.
• Put a few firm strokes on every tooth. File all left hand cutters in one direction
(Fig. 24). Then move to the other side and file the right hand cutters in the
opposite direction. Occasionally remove filings from the file with a wire brush.
Top Plate Filing Angle
• CORRECT (30°) – File holders are marked with guide marks to align the file
properly and produce the correct top plate angle (Fig. 25).
• INCORRECT (LESS THAN 30°) – For cross cutting (Fig. 26).
• INCORRECT (MORE THAN 30°) – This creates a feathered edge that dulls quickly.
Side Plate Filing Angle
• CORRECT (80°) – This is produced automatically if the correct diameter file is
used in the file holder (Fig. 25).
• INCORRECT (HOOK) – This causes the chain to “grab” and dull quickly,
increasing the potential for kickback. A hook is caused by using a file with too
small a diameter or a file held too low (Fig. 26).
• INCORRECT (BACKWARD SLOPE) – This causes a need for too much feed
pressure, producing excessive wear to the bar and chain. A backward slope
is caused by using a file with too large a diameter or a file held too high.
MAINTAINING DEPTH GAUGE CLEARANCE
• Maintain the depth gauge at a clearance of 1/32 inch (0.6 mm) (Fig. 21). Use a
depth gauge tool for checking the depth gauge clearances.
• Every time the chain is filed, check the depth gauge clearance.
• Use a flat file and a depth gauge jointer to lower all gauges uniformly (Fig. 27).
Use a 1/32 inch (0.6 mm) depth gauge jointer. After lowering each depth
gauge, restore the original shape by rounding the front (Fig. 28). Be careful
not to damage adjoining drive links with the edge of the file.
• Depth gauges must be adjusted with the flat file in the same direction the
adjoining cutter was filed with the round file.
• Use care not to contact the cutter face with the flat file when adjusting depth
gauges.
MAINTAINING THE GUIDE BAR
After every week of use, rotate the guide bar on the saw to distribute the wear for
maximum guide bar life (Fig. 29). Frequently check the guide bar for damage.
Feathering and burring of the guide bar rails (the ridges on either side of the bar
groove) is a normal process of guide bar wear. Such faults should be smoothed
with a file as soon as they occur.
A guide bar with the following faults should be replaced:
• Wear inside the guide bar rails that permits the chain to lay sideways.
• Bent guide bar.
• Cracked or broken rails.
• Spread rails.

ADJUSTING THE CHAIN TENSION
The chain must be tensioned whenever the flats on the drive links hang out of the
bar groove (Fig. 12). Check for proper chain tension before starting the unit and
periodically during operation.
NOTE: A new chain tends to stretch. Check the chain tension frequently and
tighten as required.
1. Stop the motor, make sure the lock-off button is in the locked or OFF
position and remove the battery from the unit. Refer to Removing the Battery
in the Assembly Instructions section.
2. Slightly loosen the bar cover bolt (Fig. 13).
3. Rotate the chain-tensioning bolt (Fig. 14) clockwise with a hex wrench (Allen
wrench) to tension the chain. The desired tension depends on the
temperature of the chain:
• Cold Chain Tensioning - A cold chain is correctly tensioned when there is
no sag on the underside of the guide bar and the chain seats snugly
against the guide bar with the drive links in the bar groove.
• Warm Chain Tensioning - During normal operation, the temperature of the
chain will increase. The drive links of a correctly tensioned warm chain will
hang approximately 1/16 inch (1.3 mm) out of the bar groove (Fig. 15).
4. Once adjusted, lift the tip of the guide bar up to check for proper tension
(Fig. 16). If the chain is still too loose, release the tip of the guide bar and turn
the chain-tensioning bolt 1/2 turn clockwise. Repeat this process until the
desired tension is achieved.
NOTE: If the chain is too tight, it will not rotate. To loosen the chain, turn the
chain-tensioning bolt 1/4 turn counterclockwise. Ensure that the chain can be
turned by hand without binding (Fig. 17).
5. Hold the tip of the guide bar up and rotate the bar cover bolt clockwise to secure.
REMOVING/REPLACING THE GUIDE BAR AND CHAIN
Use only a low-kickback chain on this saw. This fast-cutting chain provides
kickback reduction when properly maintained.
NOTE: When replacing the guide bar and chain, use only manufacturer
suggested replacement parts. The use of any other parts may create a hazard
or cause product damage and will VOID the warranty.
Removing the Old Guide Bar and Chain
1. Make sure the lock-off button is in the locked or OFF position and remove
the battery from the unit.
2. Rotate the bar cover bolt counterclockwise and remove the bar cover bolt,
sleeve and bar cover (Fig. 14).
3. Remove the guide bar and chain from the mounting surface.
4. Remove the old chain from the guide bar.
Installing the New Guide Bar and Chain
1. Lay out the new saw chain in a loop and straighten any kinks. The cutters on
the top of the guide bar should face toward the guide bar tip in the direction
of chain rotation (Fig. 18). If they face backward, turn the loop over.
2. Place the chain drive links into the bar groove as shown (Fig. 19).
NOTE: Make sure the chain is correctly installed and the cutters are facing in the
correct direction (Fig. 18).
3. Position the chain so there is a loop at the back of the guide bar.
4. Hold the chain in position on the guide bar and place the loop around the
drive sprocket.
5. Fit the guide bar flush against the mounting surface so that the bar stud is in
the
bar stud slot
.
NOTE: When placing the guide bar on the bar stud, ensure that the chain-
tensioning pin is in the chain tension pin hole (Fig. 20).
6. Replace the bar cover, sleeve and bar cover bolt. To tighten, rotate the bar
cover bolt clockwise with a hex wrench (Allen wrench).
NOTE: Tighten the bar cover bolt to finger tightness only. The guide bar should
still be free to move for chain tension adjustment.
7. Adjust the chain tension. Refer to the Adjusting the Chain Tension
instructions above.
