GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety
warnings and all instructions.
Failure to follow the warnings and
instructions may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for
future reference.
The term “power tool” in the warnings refers
to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in
explosive atmospheres, such as in
the presence of flammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
c) Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose
control.
2) Electrical safety
a) Power tool plugs must match the
outlet. Never modify the plug in any
way. Do not use any adapter plugs
with earthed (grounded) power
tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes,
radiators, ranges and refrigerators.
There is an increased risk of electric
shock if your body is earthed or
grounded.
c) Do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
d) Do not abuse the cord. Never use
the cord for carrying, pulling or
unplugging the power tool. Keep
cord away from heat, oil, sharp
edges or moving parts. Damaged
or entangled cords increase the risk of
electric shock.
e) When operating a power tool
outdoors, use an extension cord
suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk
of electric shock.
f) If operating a power tool in a
damp location is unavoidable, use
a residual current device (RCD)
protected supply. Use of an RCD
reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are
doing and use common sense when
operating a power tool. Do not use
a power tool while you are tired or
under the influence of drugs, alcohol
or medication. A moment of inattention
while operating power tools may result
in serious personal injury.
b) Use personal protective equipment.
Always wear eye protection.
Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or
hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting.
Ensure the switch is in the off-
position before connecting to power
source and/or battery pack, picking
up or carrying the tool. Carrying
power tools with your finger on the
switch or energising power tools that
have the switch on invites accidents.
d) Remove any adjusting key or
wrench before turning the power
tool on. A wrench or a key left attached
to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper
footing and balance at all times. This
enables better control of the power tool
in unexpected situations.
f) Dress properly. Do not wear loose
clothing or jewellery. Keep your
hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.

Chain saw EN
11
g) If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use of
dust collection can reduce dust-related
hazards.
4) Power tool use and care
a) Do not force the power tool. Use
the correct power tool for your
application. The correct power tool will
do the job better and safer at the rate for
which it was designed.
b) Do not use the power tool if the
switch does not turn it on and off.
Any power tool that cannot be controlled
with the switch is dangerous and must be
repaired.
c) Disconnect the plug from the
power source and/or the battery
pack from the power tool before
making any adjustments, changing
accessories, or storing power
tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to operate
the power tool. Power tools are
dangerous in the hands of untrained
users.
e) Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
g) Use the power tool, accessories
and tool bits etc. in accordance
with these instructions, taking into
account the working conditions and
the work to be performed. Use of
the power tool for operations different
from those intended could result in a
hazardous situation.
5) Service
a) Have your power tool serviced by
a qualified repair person using only
identical replacement parts.This will
ensure that the safety of the power tool is
maintained.
CHAIN SAW SAFETY WARNINGS
1. Keep all parts of the body away from
the saw chain when the chain saw
is operating. Before you start the
chain saw, make sure the saw chain
is not contacting anything. A moment
of inattention while operating chain saws
may cause entanglement of your clothing
or body with the saw chain.
2. Always hold the chain saw with your
right hand on the rear handle and
your left hand on the front handle.
Holding the chain saw with a reversed
hand configuration increases the risk of
personal injury and should never be done.
3. Hold the power tool by insulated
gripping surfaces only, because the
saw chain may contact hidden wiring
or its own cord. Saw chains contacting a
“live” wire may make exposed metal parts
of the power tool “live” and could give the
operator an electric shock.
4. Wear safety glasses and hearing
protection. Further protective
equipment for head, hands, legs
and feet is recommended. Adequate
protective clothing will reduce personal
injury by flying debris or accidental
contact with the saw chain.
5. Do not operate a chain saw in a tree.
Operation of a chain saw while up in a tree
may result in personal injury.
6. Always keep proper footing and
operate the chain saw only when
standing on fixed, secure and level
surface. Slippery or unstable surfaces
such as ladders may cause a loss of
balance or control of the chain saw.
7. When cutting a limb that is under
tension be alert for spring back. When
the tension in the wood fibres is released
the spring loaded limb may strike the

Chain saw EN
12
operator and/or throw the chain saw out
of control.
8. Use extreme caution when cutting
brush and saplings. The slender
material may catch the saw chain and
be whipped toward you or pull you off
balance.
9. Carry the chain saw by the front
handle with the chain saw switched
off and away from your body. When
transporting or storing the chain saw
always fit the guide bar cover. Proper
handling of the chain saw will reduce the
likelihood of accidental contact with the
moving saw chain.
10.Follow instructions for lubricating,
chain tensioning and changing
accessories. Improperly tensioned
or lubricated chain may either break or
increase the chance for kickback.
11.Keep handles dry, clean, and free
from oil and grease. Greasy, oily
handles are slippery causing loss of
control.
12.Cut wood only. Do not use chain
saw for purposes not intended. For
example: do not use chain saw for
cutting plastic, masonry or non-wood
building materials. Use of the chain saw
for operations different than intended
could result in a hazardous situation.
13.Using of a residual current device with
a tripping current of 30 mA or less is
recommended.
Causes and operator prevention of
kickback
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.
Tip contact in some cases may cause a
sudden reverse reaction, kicking the guide
bar up and 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 you to
lose control of the saw which could result
in serious personal injury. Do not rely
exclusively upon the safety devices built into
your saw. As a chain saw user, you should
take several steps to keep your cutting jobs
free from accident or injury.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper
precautions as given below:
- Maintain a firm grip, with thumbs
and fingers encircling the chain saw
handles, with both hands on the saw
and position your body and arm to
allow you to resist kickback forces.
Kickback forces can be controlled by the
operator, if proper precautions are taken.
Do not let go of the chain saw.
- Do not overreach and do not cut
above shoulder height. This helps
prevent unintended tip contact and
enables better control of the chain saw in
unexpected situations.
- Only use replacement bars and
chains specified by the manufacturer.
Incorrect replacement bars and chains
may cause chain breakage and/or kickback.
- Follow the manufacturer’s sharpening
and maintenance instructions for the
saw chain. Decreasing the depth gauge
height can lead to increased kickback.
SAVE THESE INSTRUCTIONS
Instructions concerning the proper
techniques for basic felling, limbing, and
cross-cutting
1. Felling a tree
When bucking and felling operations are
being performed by two or more persons at
the same time, the felling operations should
be separated from the bucking operation by
a distance of at least twice the height of the
tree being felled.Trees should not be felled in
a manner that would endanger any person,
strike any utility line or cause any property
damage. If the tree does make contact with
any utility line, the company should be
notified immediately.
The chain saw operator should keep on the
uphill side of the terrain as the tree is likely to
roll or slide downhill after it is felled.
An escape path should be planned and

Chain saw EN
13
cleared as necessary before cuts are started.
The escape path should extend back and
diagonally to the rear of the expected line of
fall as illustrated in Figure 1.
Before felling is started, consider the natural
lean of the tree, the location of larger
branches and the wind direction to judge
which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples
and wire from the tree.
2. Notching undercut
Make the notch 1/3 the diameter of the
tree, perpendicular to the direction of falls
as illustrated in Figure 1. Make the lower
horizontal notching cut (W) first.This will help
to avoid pinching either the saw chain or the
guide bar when the second notch (X) is being
made.
3. Felling back cut
Make the felling back cut (Y) at least 50 mm
higher than the horizontal notching cut as
illustrated in Figure 1. Keep the felling back
cut parallel to the horizontal notching cut.
Make the felling back cut so enough wood is
left to act as a hinge.The hinge wood keeps
the tree from twisting and falling in the wrong
direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree
should begin to fall. If there is any chance
that the tree may not fall in desired direction
or it may rock back and bind the saw chain,
stop cutting before the felling back cut is
complete and use wedges of wood, plastic or
aluminium (Z) to open the cut and drop the
tree along the desired line of fall ( 3).
When the tree begins to fall remove the chain
saw from the cut, stop the motor, put the
chain saw down, then use the retreat path
planned ( 2). Be alert for overhead limbs
falling and watch your footing.
4. Limbing a tree
Limbing is removing the branches from a
fallen tree. When limbing leave larger lower
limbs to support the log off the ground.
Remove the small limbs in one cut as
illustrated in Figure 2. Branches under tension
should be cut from the bottom up to avoid
binding the chain saw.
5. Bucking a log
Bucking is cutting a log into lengths. It is
important to make sure your footing is firm
and your weight is evenly distributed on both
feet. When possible, the log should be raised
and supported by the use of limbs, logs or
chocks. Follow the simple directions for easy
cutting.
When the log is supported along its entire
length as illustrated in Figure 3, it is cut
from the top (overbuck) , avoid contacting
ground as this will greatly reduce the chain
sharpness.
When the log is supported on one end, as
illustrated in Figure 4, cut 1/3 the diameter
from the underside (underbuck) (1).Then
make the finished cut by overbucking (2) to
meet the first cut.
When the log is supported on both ends, as
illustrated in Figure 5, cut 1/3 the diameter
from the top (overbuck) (1). Then make the
finished cut by underbucking (2) the lower 2/3
to meet the first cut.
When bucking on a slope always stand on
the uphill side of the log, as illustrated in
Figure 6. When “cutting through”, to maintain
complete control release the cutting pressure
near the end of the cut without relaxing your
grip on the chain saw handles. Don’t let the
chain contact the ground. After completing
the cut, wait for the saw chain to stop before
you move the chain saw. Always stop the
motor before moving from tree to tree.

carefully.
INTENDED USE
The chain saw is intended for sawing of trees,
tree trunks, branches, wooden beams, planks,
etc. Cuts can be sawed with or across the
grain.This product is not suitable for sawing
mineral materials.
ASSEMBLY
WARNING! Do not connect the
chain saw to mains before it is
completely assembled.
Always use gloves when handling the
chain.
CHAIN AND CHAIN BAR ASSEMBLY
1. Unpack all parts carefully.
2. Place the chain saw on a solid, level surface.
3. Use only genuine WORX chains or
those recommended for Guide Bar.
4. Slide the Chain (10) in the slot around the
Guide Bar (9). Ensure the Chain is in correct
running direction by comparing it to the
chain icon on the guide bar, or referring to
the Chain Direction Symbol (16) found on
the saw body. Ensure the BarTensioning
Plate (22) is facing outwards. (See Fig. A)
5. Fit the Chain onto the Drive Sprocket (15),
so that the Fastening Bar Hole (19) and the
two Bar LocatingTabs (20) on the Bar Pad
(18) fit into the keyway of the opening on
the Guide Bar (9). (See Fig. B1, B2)
6. Assure all parts are seated properly. Make
sure the drive links are fully seated in the
drive sprocket (See Fig. C1), avoiding a kink
as shown in Fig. C2. If kink occurs, pick up
on the chain at the guide bar just ahead of
the kink and then pull the kink out.
NOTE: Chain should rotate freely and be
free of kinks.
7. Fit the Chain Cover (12) and tighten
the Chain Cover by turning the Chain
Tensioning Knob (11) clockwise until it is
tight. (See Fig. D)

Chain saw EN
15
WARNING: The chain is not
yet tensioned. Tensioning the
chain applies as described under
“TENSIONING CHAIN”. The chain now
needs to be inspected to make sure it is
properly tensioned.
TENSIONING CHAIN (See Fig. E1, E2)
NOTE: New saw chains will stretch. Check the
chain tension frequently when first used and
tighten when the Chain (10) becomes loose
around the Guide Bar (9).
WARNING:
• Unplug chain saw from power source
before adjusting saw chain tension.
• Cutting edges on chain are sharp.
Use protective gloves when handling
chain.
• Maintain proper chain tension always.
A loose chain will increase the risk
of kickback. A loose chain may jump
out of guide bar groove. This may
injure operator and damage chain. A
loose chain will cause chain, bar, and
sprocket to wear rapidly.
1. Place the chain saw on any suitable flat
surface.
2. Turn the ChainTensioning Knob (11)
clockwise until it is hand tight.
NOTE:The tension is automatically increased
while the ChainTensioning Knob (11) is being
turned in a clockwise direction. The ratchet
mechanism prevents the chain tension from
loosening.
3. Tilt the saw forward (See E1) where the
Guide Bar (9) tip is pushed in an upward
direction.This will remove slack from the
chain.
4. Fully tighten the ChainTensioning Knob (11)
by turning it clockwise.
5. Double check the tension set by the
automatic ChainTensioning Knob.The
correct chain tension is reached when the
Chain (10) can be raised approx. half the
drivelink depth from the Guide Bar (9) in
the center.This should be done by using
one hand to raise the chain against the
weight of the machine. (See Fig. E2)
NOTE: The Chain (10) is properly tensioned
when it can be lifted off of the Guide Bar (9)
and the drivelink is within the rail of the Guide
Bar (9).
NOTE: The Chain (10) will stretch while
cutting and lose proper tension.When the
chain becomes loose, completely unscrew the
ChainTensioning Knob (11) or turn the knob
around three full turns in a counter-clockwise
direction, then retighten the ChainTensioning
Knob (11) to properly reset the chain tension
by repeating Steps 1-4 listed above.
LUBRICATION
IMPORTANT: The chain saw is not
filled with oil. It is essential to fill
with oil before use. Never operate the
chain saw without chain oil or at an
empty oil tank level, as this will result in
extensive damage to the product.
Filling oil tank:
WARNING: Unplug chain saw from
power source before filling the oil
tank.
1. Set chain saw on any suitable surface
with Oil Filler Cap (5) facing upward.
2. Clean area around the Oil Filler Cap with
cloth and unscrew the cap by turning it
counter clockwise.
3. Add bar and chain oil until tank is full.
4. Avoid dirt or debris entering oil tank, refit
Oil Filler Cap (5) and tighten by turning
clockwise until hand tight.
IMPORTANT: To allow venting
of the oil tank, small breather
channels are provided between the Oil
Filler Cap and the strainer, to prevent
leakage, and ensure machine is left in
a horizontal position (Oil Filler Cap (5)
uppermost) when not in use.
It is important to use only the
recommended standard bar and chain oil
(Grade: ISO VG32) to avoid damage to
the chain saw. This can be found at the
location where you purchased this saw
or your local hardware store. Never use
recycled/old oil. Use of non approved oil
will void the warranty.

Chain saw EN
16
Oiling chain
Always check oil level before using saw. Do
not attempt to operate the oil system while
saw is in operation.To oil chain, press Bulb
(23). Oil will feed through the Oil Outlet (17)
onto the Guide Bar (9) and chain. Press Bulb
(23) on Oil Filler Cap at least once before each
cut (See Fig. F).
OPERATION
1. SWITCHING ON AND OFF (See Fig. G)
ATTENTION: Check the voltage and
current supply: The voltage and
current supply must comply with the
ratings on the product plate.
For switching on the tool, press the Lock-Out
Button (3), then fully press the On/Off Switch
(2) and hold in this position.The Lock-Out
Button can now be released.
For switching off, release the On/Off Switch.
2. CHAIN BRAKE (See Fig. H)
The chain brake is a safety mechanism
activated through the hand guard (7). When
kickback occurs, chain stops immediately.
The following function check should be
carried out at regular intervals as pushing
hand guard (7) forwards (position ) and
start the chain saw, the chain will not start.To
deactivate the kickback brake, pull hand guard
(7) backwards (position ),and release On/Off
switch (2).
3. CUTTING
IMPORTANT: Check the Oil Level
Window (4) prior to starting and
regularly during operation. Refill oil
when oil level is low. A full oil tank
will last approx. 12 minutes of cutting
depending on sawing intensity and stops
(See Fig. I1).
Check recent replaced chain tension
about every 10 minutes during
operation.
(1) Connect saw to extension cord. Connect
extension cord to power supply. (See Fig.
I2)
(2) Make sure section of log to be cut is not
laying on the ground.This will keep the
chain (10) from touching the ground as it
cuts through the log.
Touching the ground while the Chain is
moving is dangerous and will dull the
Chain.
(3) Use both hands to grip saw. Always use
left hand to grip Front Handle (6) and
right hand to grip Rear Handle (1). Use a
firm grip.Thumbs and fingers must wrap
around saw handles (See Fig.I3 ).
(4) Make sure your footing is firm. Keep feet
shoulder width apart. Distribute your
weight evenly on both feet.
(5) When ready to make a cut, push the
Lock-Out Button (3) completely in with
the right thumb and squeeze the trigger.
This will turn the saw on. Releasing the
trigger will turn the saw off. Make sure
the saw is running at full speed before
starting a cut.
(6) When starting a cut, slowly place moving
chain against the wood.The wood
should be as close to the sawbody as
possible. Hold saw firmly in place to avoid
possible bouncing or skating (sideways
movement) of saw.
(7) Guide the saw using light pressure and do
not put excessive force on the saw, letting
the saw do its work, or the motor will
overload and can burn out. It will do the
job better and safer at the rate for which it
was intended.
(8) Remove the saw from a cut with the saw
running at full speed. Stop the saw by
releasing the On/off Switch (2). Make sure
the chain has stopped before setting the
saw down.
(9) Keep practicing on scrap logs in a secure
working area until you are comfortable,
using a fluid motion and a steady cutting
rate.
Kickback Safety Devices On This Saw
This saw has a low-kickback chain and
reduced kickback Guide Bar. Both items
reduce the chance of kickback. However,
kickback can still occur with this saw.
The following steps will reduce the risk of
kickback.
• Use both hands to grip saw while saw

Chain saw EN

is running. Use firm grip.Thumbs and
fingers must wrap around saw handles.
• Keep all safety items in place on saw.
Make sure they work properly.
• Do not overreach or cut above shoulder
height.
• Keep solid footing and balance at all times.
• Stand slightly to left side of saw.This
keeps your body from being in direct line
with chain.
• Do not let Guide Bar nose touch anything
when chain is moving.
• Never try cutting through two logs at
same time. Only cut one log at a time.
• Do not bury the Guide Bar nose or try
plunge cut (boring into wood using
Guide Bar nose).
• Watch for shifting of wood or other
forces that may pinch chain.
• Use extreme caution when reentering a
previous cut.
• Use only the low-kickback chain and
Guide Bar (9) that were supplied with this
chain saw or recommended.
• Never use a dull or loose chain. Keep
chain sharp with proper tension.
How to use Saw Safely
1. Use the chain saw only with secure footing.
2. Hold the chain saw at the right-hand side
of your body (See Fig. J).
3. The Chain (10) must be running at full
speed before it makes contact with the
wood.
4. Use the Bumper Spikes (8) to secure the
saw onto the wood before starting to cut.
5. Use the Bumper Spikes as a leverage
point while cutting. (See Fig. K)
6. Do not operate the chain saw with arms
fully extended, or attempt to saw areas
which are difficult to reach, or stand on a
ladder while sawing (See Fig. L).
7. Never use the chain saw above
shoulder height.
Cutting wood under tension (See Fig. M)
WARNING: When cutting a limb
that is under tension, use extreme
caution. Be alert for wood springing
back. When wood tension is released,
limb could spring back and strike
operator causing severe injury or death.
When sawing logs supported on both ends,
start the cut from above(Y) about 1/3 of the
diameter into the log (overbuck) and then
finish the cut (Z) from below, in order to avoid
contact of the chain saw with the ground.
When sawing logs supported on only one
end, start the cut from below (Y) about 1/3
of the diameter into the log (underbuck) and
finish the cut from above (Z) in order to avoid
log splitting or jamming of the chain saw.
SAW MAINTENANCE
Follow maintenance instructions in this
manual. Proper cleaning of saw and chain and
Guide Bar maintenance can reduce chances
of kickback. Inspect and maintain saw after
each use.This will increase the service life of
your saw.
NOTE: Even with proper sharpening,
risk of kickback can increase with each
sharpening.
MAINTENANCE AND
STORAGE OF CHAIN SAW
WARNING: If the supply cord is
damaged, it must be replaced by the
manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
1. Unplug chain saw from power source
• When not in use
• Before moving from one place to another
• Before servicing
• Before changing accessories or
attachments, such as saw chain and
guard
2. Inspect chain saw before and after each
use. Check saw closely if guard or other part
has been damaged. Check for any damage
that may affect operator safety or operation
of saw. Check for alignment or binding of
moving parts. Check for broken or damaged
parts. Do not use chain saw if damage affects
safety or operation. Have damage repaired
by authorized service center.To locate an
authorized service center, visit www.worx.

3. Maintain chain saw with care.
• Never expose saw to rain or direct moisture.
• Keep chain sharp, clean, and lubricated
for better and safer performance.
• Follow steps outlined in this manual to
sharpen chain.
• Keep handles dry, clean, and free of oil
and grease.
• Keep all screws and nuts tight.
• Inspect power cord often. If damaged, have
repaired by authorized service center.
• Never carry chain saw by power cord.
• Never yank power cord to unplug it.
• Keep power cord from heat, oil, and
sharp edges.
• Inspect extension cords often and replace
if damaged.
4. When servicing, use only identical
replacement parts.
5. When not in use, always store chain saw
• In a high or locked place, out of children’s reach
• In a dry place
• With Bar and Chain Storage Cover(21) in place
BAR MAINTENANCE
To maximize bar life, the following bar
maintenance is recommended.
The bar rails that carry the chain should be
cleaned before storing the tool or if the bar or
chain appear to be dirty.
The rails should be cleaned every time the
chain is removed.
To clean the Bar rails:
1. Remove chain cover and bar and chain.
(see Section ASSEMBLY)
2. Using a wire brush, screwdriver or
similar tool, clear the residue from the
inner groove of the bar. (See Fig. N)
3. Make sure to clean oil passages
thoroughly
Conditions which require Chain (10) and
Guide Bar (9) maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• Inadequate supply of oil to the bar and
chain.
Check the condition of the Guide Bar each
time the chain is sharpened. A worn Guide
Bar will damage the chain and make cutting
difficult.
After each use, with unit disconnected from
power source, clean all sawdust from the
Guide Bar and sprocket hole.
When rail top is uneven, use a flat file to
restore square edges and sides.
File Rail Edges
and Sides
Square
Worn Groove Correct Groove
Replace the Guide Bar when the groove is
worn, the Guide Bar is bent or cracked, or
when excess heating or burring of the rails
occurs. If replacement is necessary, use only
the Guide Bar specified for your saw in the
repair parts list or on the decal located on the
chain saw.
Replacing Bar & Chain
Replace chain when cutters are too worn
to sharpen or when chain stops. Only use
replacement chain noted in this manual.
Inspect Guide Bar before sharpening chain.
A worn or damaged Guide Bar is unsafe. A
worn or damaged Guide Bar will damage
chain. It will also make cutting harder.
Fit the BarTensioning Plate (22)Tab into the
new bar by tightening the screw clockwise.
The tab protrusion (a) must be fitted into the
bar hole. (See Fig. O)
Sharpening Saw Chain
WARNING: Unplug chain saw from
power source before servicing.
Severe injury or death could occur from
electrical shock or body contact with
moving chain.
Cutting edges on chain are sharp. Use
protective gloves when handling chain.
Keep chain sharp. Your saw will cut faster
and more safely. A dull chain will cause undue
sprocket, Guide Bar, chain, and motor wear.
If you must force chain into wood and cutting
creates only sawdust with few large chips, chain
is dull.
