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 make cuts with the tip of the guide bar (Fig. 1).
• 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.
• Stand slightly to the left of the unit to avoid being in the direct line of the saw chain. Follow all the
Proper Grip on Handles instructions in the Operating Instructions section.
• Never start the saw when the guide bar is inside an existing cut. Be extremely careful when reentering a cut.
• Always begin a cut with the motor running at full speed. 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.
• If using wedges, only use wedges made of plastic or wood. Do not use metal to hold a cut open.
• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
• Only use replacement bars and chains specified by the manufacturer or the equivalent. These are
available from authorized service dealers. Use of any unauthorized parts or accessories could lead
to serious injury to the operator or damage to the unit and will void the warranty.
• Use devices, such as low-kickback chains, guide bar nose guards, chain brakes and special guide
bars, which reduce the risks associated with kickback. There are no other replacement
components for achieving kickback protection in accordance with CSA Z62.3.
•
Low-kickback saw chain is chain that has met the kickback performance requirements of ANSI
B175.1-1991 and is in accordance with CSA Z62.3. Do not use a replacement chain unless it has met
these requirements for the specific model. As saw chains are sharpened, some of the low kickback
qualities are lost and extra caution should be used.
POLE SAW SAFETY PRECAUTIONS
• DO NOT cut near electrical cables or power lines.
• DO NOT use a pole saw to fell a tree. Use a standard chain saw for this application.
• When cutting a limb that is under tension, be alert for spring back, which may cause the operator to
be struck when the tension of the wood fibers is released.
• Use extreme caution when cutting small-sized brush and saplings, as slender material may catch
the saw chain and be whipped toward the operator or pull the operator off balance.
• This saw is classified by UL as a Class 2C saw. It is intended for infrequent use by homeowners,
cottagers and campers, and for general applications such as clearing, pruning, cutting firewood,
etc. It is not intended for prolonged use. If the intended use involves prolonged periods of
operation, this may cause circulatory problems in the user’s hands due to vibration. It may be
appropriate to use a saw having an anti-vibration feature.
GENERAL SAFETY PRECAUTIONS
• DO NOT handle the unit, plug or cord with wet hands.
• DO NOT over reach.
• DO NOT
operate the unit on unstable surfaces, such as in trees or on ladders, slopes or rooftops.
Be very careful when using the unit on stairs.
• DO NOT expose the unit to rain. Do not use the unit in damp or wet locations or conditions.
• DO NOT
operate the unit on wet surfaces.
• DO NOT use the unit in the presence of flammable liquids or gases.
• DO NOT operate a unit that is damaged, improperly adjusted or not completely and securely
assembled. Be sure that the unit stops when the trigger is released. Do not use the unit if the
trigger does not turn the unit on and off properly. Have defective triggers replaced by an authorized
service center.
• DO NOT attempt operations beyond the operator’s capacity or experience.
• DO NOT operate the unit with one hand! Serious injury to the operator, helpers or bystanders may
result from one-handed operation. This unit is intended for two-handed use. Grip the unit firmly with
both hands when the motor is running. Keep the left hand on the D-handle and the right hand on
the shaft grip. Use a firm grip with thumbs and fingers encircling the handles. Do not let go!
• DO NOT force the unit. It will do a better, safer job when used at the intended rate.
• DO NOT leave the unit unattended while the unit is connected to the power source. Unplug the unit
from the power source when not in use.
• Adjust the D-handle to provide the best grip.
• Keep hair, loose clothing, fingers and all other body parts away from moving parts. Do not try to
touch or stop moving parts (cutting attachment or pole saw chain) when they rotate.
• Keep proper footing and balance at all times.
• Make sure the cutting attachment/pole saw chain is not in contact with anything before starting the unit.
• Always stop the motor when operation is delayed, before setting down the unit or when walking
from one location to another. Make sure the unit comes to a complete stop.
•
To avoid accidental starting, never carry the unit with fingers on the trigger.
• Always make sure the trigger is released before connecting or disconnecting the unit from the
power source.
•
Always carry the unit with both hands, with the unit disconnected from the power source and finger off
the trigger. When used as a pole saw, always carry the unit with the guide bar and chain sheathed in the
scabbard and positioned to the rear.
• If the unit strikes or becomes entangled with a foreign object, stop the motor immediately,
disconnect the unit from the power source and check for damage. Do not restart or operate the unit
before repairing damage.
SAFETY INFORMATION
ELECTRICAL SAFETY PRECAUTIONS
• DO NOT abuse the extension cord. Never pull or carry the unit by the cord, use the cord as a
handle, close a door on a cord, pull the cord around sharp edges or corners or yank the cord to
disconnect the unit. Grasp the plug, not the cord, to disconnect the unit.
• DO NOT modify the extension cord, plug or wall outlet in any way.
• DO NOT use multiple extension cords.
• Keep the cord away from oil, water, sharp objects and heated surfaces.
• Keep the cord away from the cutting area and position the cord so that it will not be caught on
branches or other obstacles that may bind or entangle the cord during operation.
• Keep the cord away from the operator’s feet to prevent tripping.
• Make sure the cord is in good condition. Inspect the extension cord periodically. Look closely for
deterioration, cuts or cracks in the insulation. If the extension cord is damaged, replace it. Do not
use a damaged cord or plug.
• If the extension cord is damaged in any manner while plugged in, disconnect the extension cord
from the receptacle.
• Since the unit is double-insulated, a 2-wire extension cord (one without a ground) may be used.
However, a 3-wire extension cord (one with a ground) that uses a NEMA-type connector (parallel
blade, U ground) is recommended. Extension cords are available from local retailers. Use only
round-jacketed extension cords approved for outdoor use.
• Make sure the extension cord is heavy enough to carry the current drawn by the unit. An
undersized cord will cause a drop in line voltage resulting in loss of power and overheating. If in
doubt, use the next heavier gauge cord. The smaller the gauge number, the heavier the cord.
• To reduce the risk of electrical shock, this unit has a polarized plug (one blade is wider than the
other) and will require the use of a polarized extension cord. The recessed plug will fit into a
polarized extension cord only one way. If the plug does not fit fully into the extension cord, reverse
the plug. If the plug still does not fit, obtain another polarized extension cord. A polarized extension
cord will require the use of a polarized wall outlet. This plug will fit into the polarized wall outlet only
one way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not
fit, contact a qualified electrician to install the proper wall outlet.
• A nameplate on your unit indicates the voltage used. Never connect the unit to an AC voltage that
differs from this voltage.
• Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) that
will be used with the unit. For an extra measure of safety, use receptacles with built-in GFCI protection.
• To reduce the likelihood of disconnecting the extension cord from the unit, be sure to use the cord
retainer provided.
• To reduce the risk of electric shock, avoid body contact with grounded conductors, such as metal
pipes or wire fences.
SERVICING A DOUBLE-INSULATED UNIT
• This is a double-insulated unit. Two systems of insulation are provided instead of grounding. There is
no grounding provided and no means of grounding should be added to the unit. Servicing a doubleinsulated unit requires extreme care and knowledge of the system and should only be done by
qualified service personnel. Replacement parts for a double-insulated unit must be identical to the
parts they replace. Failure to have a double-insulated unit repaired by an authorized service
technician with identical replacement parts could result in serious injury.
MAINTENANCE AND STORAGE SAFETY
• If the unit is not working as it should, has been dropped, damaged, left outdoors or dropped into
water, do not use the unit. Have the unit serviced by an authorized service center.
• All service, other than the maintenance procedures described in this manual, should be performed
by an authorized service center. Do not attempt to repair; there are no user serviceable parts inside.
• Follow all maintenance instructions in this manual.
• Before inspecting, servicing, cleaning, storing, transporting, replacing parts or changing
accessories on the unit:
1. Stop the motor. Make sure the trigger is released.
2. Make sure all moving parts have stopped.
3. Disconnect the unit from the power source.
4. Allow the unit to cool.
• Never remove, modify or make inoperative any safety device furnished with the unit.
• For safer, more effective performance, make sure the bar and chain are properly cleaned, lubricated,
tightened and sharpened. Check the bar and chain at frequent intervals for proper adjustment.
• Frequently inspect the unit for damage. Before further use, any damaged part should be carefully
checked to determine that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts and any other conditions
that may affect its operation. Damaged parts should be properly repaired or replaced by an
authorized service center, unless otherwise indicated in this manual.
• If the unit starts to vibrate abnormally, stop the motor, disconnect the unit from the power source and
allow the unit to cool. Then inspect the unit for the cause of the vibration. Vibration is generally an
indicator of trouble.
• Use only original manufacturer replacement parts and accessories, which are designed specifically to
enhance the performance and maximize the safe operation of the product. Failure to do so may cause
poor performance and possible injury. Use only the chain and guide bar supplied with this product.
• Be sure to secure the unit while transporting.
• Always use the scabbard on the bar and chain during transportation and storage.
• When not in use, store the unit indoors in a locked-up and dry, or high and dry, place to prevent
unauthorized use or damage. Keep out of the reach of children.
•
Keep the handles dry, clean and free from debris, oil and grease. Clean the unit after each use. Never
douse or spray the unit with water or any other liquid. Do not wash the unit with a hose; avoid getting
water in the motor and electrical connections.
Do not use solvents or strong detergents.

WARNING:To reduce the risk of electric shock, only use extension cords
suitable for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A,
SJTW-A or SJTOW-A cord types.
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 THE UNIT AS A TRIMMER
1. Hold the unit at waist level with the cutting attachment
parallel to the ground so that it easily contacts the grass
without the need to bend over (Fig. 14).
2. Start the motor. Refer to Starting and Stopping Instructions.
3. Slowly move the cutting attachment into and out of the
cutting area at the desired height.
• Move either in a forward-backward or side-to-side
motion. When cutting from side-to-side, cut from right to
left whenever possible. This improves the unit’s cutting
efficiency and directs clippings away from the operator.
• Cutting shorter lengths produces the best results.
• Cut grass over 8 inches (200 mm) by working from top
to bottom in small increments to avoid premature line
wear or motor drag.
• Do not force the cutting attachment. Allow the tip of the
line to do the cutting, especially along walls. Cutting
with more than the tip will reduce cutting efficiency and
may overload the motor.
• Only trim when grass or weeds are dry.
4. Dispose of debris appropriately.
Decorative Trimming
Decorative trimming is the act of removing all vegetation
from around trees, posts, fences, etc. To accomplish it,
rotate the whole unit so that the cutting attachment is at a
30˚ angle to the ground (Fig. 15).
Adjusting the Trimming Line Length
The Bump Head
TM
cutting attachment allows the release of
trimming line without having to stop the motor. To release
more line, lightly tap the cutting attachment to the ground
(Fig. 16) while operating the unit at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult when the
cutting line gets shorter.
Each time the head is bumped, about 1 inch (25.4 mm) of
trimming line releases. A blade in the cutting attachment
shield will cut the line to the proper length if any excess line
is released.
For best results, tap the bump knob on bare ground or hard soil. If you attempt a line release in tall
grass, the motor may stall.
NOTE: Do not rest the Bump Head
TM
on the ground while the unit is running.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts
The life of the cutting line is dependent upon:
• Following these trimming instructions
• What vegetation is being cut
• Where vegetation is being cut
For example, the line will wear faster when trimming against a foundation wall than when trimming
around a tree.
OPERATING THE UNIT AS A POLE SAW
Preparation for Cutting
• To prevent electrocution, do not operate within 50 feet
(15 m) of overhead electrical lines (Fig. 17).
• Keep everyone – helpers, bystanders, children and
animals – at least 50 feet (15 m) away from the work area
(Fig. 17). If anyone enters the work area, stop the unit!
• Wear non-slip gloves for maximum grip and protection.
• Maintain a proper grip on the unit whenever the motor is
running. Hold the unit firmly with both hands. Firmly grip
the shaft grip with the right hand and the D-handle with
the left hand (Fig. 18).
• 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. 18).
• Never stand directly under the limb being cut.
Pruning
This unit is designed for trimming small branches and limbs
up to 4 inches (10 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. 18).
• Do not cut from a ladder; this is extremely dangerous. Leave this operation for professionals.
• The most typical cutting application is to position the unit at an angle of 60° or less, depending on
the specific situation (Fig. 18). 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.
• 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.
• 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.
• Avoid kickback. Kickback can result in severe injury or death. See Understanding Kickback and
Kickback Safety Precautions in the Safety Instructions section.
• Keep the unit running the entire time while cutting, making sure to maintain a steady speed.
• Allow the chain to do the cutting; exert only light downward pressure. Forcing the cut could result in
damage to the guide bar, chain or motor.
• Release the trigger as soon as the cut is completed. Allow the chain to come to a complete stop.
Unnecessary wear may occur to the chain, bar and unit if the saw is run without a cutting load.
• Do not put pressure on the saw at the end of the cut.

WARNING:
Do not remove or alter the line cutting blade assembly. Excessive line length
will make the motor overheat. This may lead to serious personal injury or damage to the unit.
OPERATING INSTRUCTIONS
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. Start the motor and let the chain accelerate to full speed
before starting the cut. Refer to Starting and Stopping
Instructions.
2. 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. 19).
3. 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.
4. 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. 20). 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.
5. 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 disconnect the unit from the power source.
• 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.

TRIMMER MAINTENANCE AND REPAIR
Line Installation
This section covers both SplitLine
TM
and standard single
line installation.
Always use original equipment manufacturer 0.080 in. (2.03
mm) replacement line. Line other than the specified may
make the motor overheat or fail.
There are two methods for replacing the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Winding New Line on the Existing Inner Reel
1. Hold the outer spool with one hand and unscrew the
bump knob counterclockwise (Fig. 21). Inspect the bolt
inside the bump knob to make sure it moves freely.
Replace the bump knob if damaged.
2. Remove the inner reel from the outer spool (Fig. 22).
3. Remove spring from the inner reel (Fig. 22).
4. Use a clean cloth to clean the inner reel, spring, shaft
and inner surface of the outer spool.
5. Check the indexing teeth on the inner reel and outer
spool for wear (Fig. 23). If necessary, remove burrs or
replace the reel and spool.
NOTE: SplitLine™ can only be used with the inner reel
with the slotted holes. Single line can be used on
either type of inner reel. Use Figure 24 to identify
the inner reel you have.
NOTE: Always use the correct line length when installing
trimming line on the unit. The line may not release
properly if the line is too long.
Single Line Installation
Go To Step 8 for SplitLine™ Installation
6. Take approximately 20 feet (6 m) of new trimming line,
loop it into two equal lengths. Insert each end of the line
through one of the two holes in the inner reel (Fig. 25).
Pull the line through the inner reel so that the loop is as
small as possible.
7. Wind the lines in tight even layers, onto the reel (Fig. 26).
Wind the line in the direction indicated on the inner reel.
Place your index finger between the two lines to stop
the lines from overlapping. Do not overlap the ends of
the line. Proceed to step 11.
SplitLine™ Installation
8. Take approximately 10 feet (3 m) of new trimming line.
Insert one end of the line through one of the two holes in
the inner reel (Fig. 27). Pull the line through the inner reel
until only about 4 inches is left out.
9. Insert the end of the line into the open hole in the inner
reel and pull the line tight to make the loop as small as
possible(Fig. 27).
10. Before winding, split the line back about 6 inches.
11. Wind the line in tight even layers in the direction
indicated on the inner reel.
NOTE: Failure to wind the line in the direction indicated
will cause the cutting attachment to operate
incorrectly.
12. Insert the ends of the line into the two holding slots (Fig. 28).
13. Insert the ends of the line through the eyelets in the
outer spool and place inner reel with spring inside the
outer spool(Fig. 29). Push the inner reel and outer spool
together. While holding the inner reel and outer spool,
grasp the ends and pull firmly to release the line from the
holding slots in the reel.
NOTE: The spring must be assembled on the inner reel
before reassembling the cutting attachment.
14. Hold the inner reel in place and install the bump knob
by turning clockwise. Tighten securely.
WARNING:

POLE SAW MAINTENANCE AND REPAIR
ADJUSTING THE CHAIN TENSION
The chain must be tensioned whenever the flats on the
drive links hang out of the bar groove (Fig. 30). 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 and disconnect the unit from the power
source. Refer to Disconnecting the Power Source in the
Assembly Instructions section.
2. Slightly loosen the bar retaining nuts (Fig. 31 B).
3. Rotate the chain-tensioning screw (Fig. 31 A) clockwise
with a standard screwdriver 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.
32
).
4. Once adjusted, lift the tip of the guide bar up to check
for proper tension (Fig. 33). If the chain is still too loose,
release the tip of the guide bar and turn the chaintensioning screw 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 screw 1/4
turn counterclockwise. Ensure that the chain can
be turned by hand without binding (Fig. 34). Also
note that the chain will not rotate if the chain
brake is engaged.
5. Hold the tip of the guide bar up and securely tighten the
bar retaining nuts.
REMOVING/REPLACING THE GUIDE BAR AND CHAIN
Use only a low-kickback saw chain that has met kickback
performance per ANSI B175.1 for 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 motor is OFF and disconnect the unit
from the power source.
2. Rotate the bar retaining nuts counterclockwise and
remove the bar retaining nuts. Using a standard
screwdriver, rotate the bar cover screw counterclockwise
(Fig. 31). Remove the bar cover screw and bar cover.
3. Using a standard screwdriver, rotate the chaintensioning screw counterclockwise 4 turns to loosen the
chain. See Adjusting the Chain Tension instructions.
4. Remove the guide bar and chain from the mounting surface.
5. 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. 35). If they face backward, turn the loop over.
2. Place the chain drive links into the bar groove as shown
(Fig. 36).
NOTE: Make sure the chain is correctly installed and the
cutters are facing in the correct direction (Fig. 35).
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 retaining bolts are in the slot (Fig. 37).
6. Adjust the chain tension. Refer to the Adjusting the
Chain Tension instructions above.
7. Replace the bar cover and bar retaining nuts. To tighten,
rotate the bar retaining nuts clockwise.
NOTE: When replacing the bar cover and bar retaining
nuts, ensure that the chain-tensioning pin is in
the chain-tensioning pin hole (Fig. 37).

MAINTENANCE AND REPAIR INSTRUCTIONS
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. 38). 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 in the areas indicated, have
the drive sprocket replaced by an authorized
service center.
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 lowkickback 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. 39).
Do not let the file dip or rock.
• Using light but firm pressure, stroke towards the front
corner of the tooth (Fig. 40). 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. 41). Then move to the other
side and file the right hand cutters in the opposite
direction (Fig. 41). 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. 42).
• INCORRECT (LESS THAN 30°) – For cross cutting (Fig. 43).
• 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. 42).
• 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. 43).
• 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" (0.6
mm). Use a depth gauge tool for checking the depth
gauge clearances. (Fig. 38)
• 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. 44). 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. 45).
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.
WARNING:
To avoid possible serious injury,
never touch or adjust the chain while the motor
is running. The saw chain is very sharp; always
wear protective gloves when performing
maintenance on the chain.
WARNING:
A chain tensioned while warm,
may be too tight upon cooling. Check the
“cold tension” before next use.

MAINTENANCE AND REPAIR INSTRUCTIONS
MAINTAINING THE GUIDE BAR
Clean the bar grooves after heavy use, when the saw chain
appears dirty and whenever the saw chain is removed.
Refer to Cleaning and Storage instructions. This will help
keep the oil passages open to provide proper lubrication to
the bar and chain.
After every week of use, rotate the guide bar on the saw to
distribute the wear for maximum guide bar life (Fig. 46).
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.
MAINTAINING THE BAR AND CHAIN LUBRICATION
Setting the Bar Lube Adjustment Screw
Oil is dispersed automatically onto the saw chain as the
unit is used. To adjust the rate of flow:
1. Insert a 3/32-inch Allen wrench into the bar lube
adjustment screw (Fig. 47).
2. Rotate the screw counterclockwise to increase the flow
of oil to the chain.
3. Rotate the screw clockwise to decrease the flow of oil to
the chain.
NOTE: Always keep an adequate amount of bar and
chain oil in the bar lube reservoir. Check the oil
level frequently and refill the reservoir as needed.
Oil Passages
The oil passages in the bar mount (Fig. 48) should be
cleared to ensure proper lubrication of the bar and chain
during operation. This can be done using a soft wire small
enough to insert into the oil discharge hole.

1. Stop the motor and wait for all moving parts to stop.
2. Disconnect the unit from the power source and allow the unit to cool. Refer to Connecting and
Disconnecting the Power Source.
3. Slacken the pole saw chain if it was retensioned at operating temperature during cutting work. The
chain contracts as it cools down. If it is not slackened, it may damage the gearbox and bearings.

strong detergents. If preparing the unit for long-term storage (three months or more), remove the
chain and guide bar, then clean the unit thoroughly with a damp cloth. A firm-bristled, non-wire,
brush can be used to remove debris from the bar groove and assembly. When finished, reassemble
the unit. Refer to Removing/Replacing the Guide Bar and Chain.
5. Spray the guide bar and chain with corrosion inhibiting oil.
