GENERAL POWER TOOL
SAFETY WARNINGS
WARNING: Read all safety warnings
and 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 refer to
your electric (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 grounded power tools.
Unmodified plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators. There is an
increased risk of electric shock if your body
is 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 ground
fault circuit interrupter (GFCI)
protected supply. Use of an GFCI
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
Electric Chain Saw EN
8
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 energizing 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 jewelry. Keep your hair,
clothing and gloves away from
moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
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
tools 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 and in the manner
intended for the particular type of
power tool, 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
Electric Chain Saw EN
9
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 fibers is released the
spring loaded limb may strike the 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 apply 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.Recommendation for the use of a
residual current device with a tripping
current of 30mA or less.
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
Electric Chain Saw EN
10
and maintenance instructions for the
saw chain. Decreasing the depth gauge
height can lead to increased kickback.
SAFETY RULES FOR EXTENSION CORD
Make sure your extension cord is in good
condition. When using an extension cord,
be sure to use one heavy enough to carry
the current your product will draw. An
undersized extension cord will cause a drop
in line voltage resulting in loss of power and
overheating. Table 1 shows the correct size to
use depending on cord length and nameplate
ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number,
the heavier the cord. To reduce the risk of
disconnection of appliance cord from the
extension cord during operating:
I) Make a knot as shown in Figure 1; or
II) Use one of the plug-receptacle retaining
straps or connectors described in this manual.

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
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 I.
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 I. 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 I. 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.
Electric Chain Saw EN

When the log is supported on one end, as
illustrated in Figure IV, cut 1/3 the diameter from
the underside (underbuck)(1). Then make the
finished cut by overbucking(2) to meet the first cut.

Fig.V
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. (

)
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 (

). 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 II. Branches under tension
should be cut from the bottom up to avoid
binding the chain saw.
Fig.II
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 III, it is cut from
the top (overbuck) , avoid contacting ground
as this will greatly reduce the chain sharpness.

SYMBOLS
To reduce the risk of injury, user
must read instruction manual.
Wear ear protection
Wear eye protection
Wear dust mask
Double insulation
Do not expose to rain
Remove plug from the mains
immediately if the cable is damaged
or cut.
Contact of the guide bar tip with any
object should be avoided.
Tip contact can cause the guide
bar to move suddenly upward and
backward, which can cause serious
injury.
Always use two hands when
operating the chain saw.
When bucking on a slope always stand on
the uphill side of the log, as illustrated in
Figure VI. 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.

ASSEMBLY
WARNING! Do not connect the
chain saw to the power supply
before it is completely assembled.
Always use gloves when handling the
chain.
CHAIN AND GUIDE 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 Bar Tensioning
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 Locating Tabs (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)
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 Chain Tensioning Knob (11)
clockwise until it is hand tight.
NOTE: The tension is automatically
increased while the Chain Tensioning Knob
(11) is being turned in a clockwise direction.
The built-in 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 Chain Tensioning Knob (11)
by turning it clockwise.(See E1)
5. Verify the correct chain tension is achieved
when the Chain (10) can be raised approx.
0.12”–0.24” (3mm-6mm) from the Guide
Bar (9). This is checked by using one hand
to raise the Chain (10) at the center of
the Guide Bar (9) against the weight of
the machine (See E2). If the chain moves
more than 0.12”-0.24” (3mm-6mm), turn
the Chain Tensioning Knob (11) three (3)
full turns in a counter-clockwise direction
to loosen the Chain Cover (12) and repeat
Steps 1-4.
NOTE: The Chain (10) will stretch while
cutting and lose proper tension. When the
chain becomes loose, completely unscrew
the Chain Tensioning Knob (11) or turn
the knob around three (3) full turns in a
counter-clockwise direction, then retighten
the Chain Tensioning Knob (11) to properly
reset the chain tension by repeating Step
1-4 listed above.

LUBRICATION
IMPORTANT: The chain saw is
not supplied 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:
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 reservoir 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 reservoir, small breather
channels are provided between the Oil
Filler Cap and the strainer, to prevent
leakage 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 you purchased this saw or
your local hardware store. Never use
recycled/old oil. Use of non approved oil
will void the warranty
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 Oil
Filler Cap (5). Oil will feed through the Oil
Outlet (17) onto the Guide Bar (9) and chain.
Press the Bulb (23) on Oil Filler Cap at least
once before each cut (See Fig. F).
WARNING! To prevent continuous
oiling after operation simply loosen the
oil cap slightly and then tighten it again.
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. CUTTING
IMPORTANT: Is the oil reservoir
filled? Check the Oil Level Window
(4) prior to starting and regularly during
operation.(See Fig. H1) Refill oil when
oil level is low. A full oil tank will last
approx. 12 minutes of cutting depending
on sawing intensity and stops. 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. H2 )
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.H3 )
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 saw body 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. The motor will
overload and can burn out. It will do the
job better and safer at the rate for which it
was intended.
Electric Chain Saw EN
15
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 and
can saw with ease, 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 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. I)
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. J)
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. K)
Never use the chain saw above shoulder
height.
CUTTING WOOD UNDER TENSION (See
Fig. L)
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) (overbuck) about
1/3 of the diameter into the log 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
If the replacement of the supply cord is
necessary, this has to be done by the
manufacturer or his agent in order to avoid a
safety hazard.
1. Unplug chain saw from power source
• When not in use
• Before moving from one place to another
Electric Chain Saw EN
16
• 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.com
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 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. M)
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.
Turn the bar over, top rail becoming bottom
and bottom rail becoming top, around every 5
hours of use. Fit the Bar Tensioning 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. N)
Sharpening Saw Chain
WARNING: Unplug chain saw from
power source before servicing.
Electric Chain Saw EN
17
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.
Lubricate Sprocket
WARNING: Wear heavy duty gloves
when performing any maintenance or
service to this tool.
Always unplug the tool before performing any
service or maintenance on this tool
NOTE: It is not necessary to remove the chain
or bar when lubricating the guide bar sprocket
1. Clean the bar and sprocket
2. Using a grease gun, insert the tip of the
gun into the lubrication hole and inject
grease until it appears at the outside edge
of the sprocket tip. (See Fig.O )
3. To rotate the sprocket pull the chain by
hand until the ungreased side of the
sprocket is in line with the grease hole.
Repeat the lubrication procedure.
