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 off­position 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.

3

Chain saw WG305E

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

4

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 WG305E

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

5

Chain saw WG305E

cleared as necessary before cuts are started.

Figure.2

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.

6

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.

Figure.2

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 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.

VIBRATION INFORMATION

Vibration total values (triax vector sum) determined according to EN 60745

Vibration emission value ah = 5.5m/s

Uncertainty K =1.5m/s²

The declared vibration total value may be used for comparing one tool with another, and may also
be used in a preliminary assessment of exposure.

WARNING: The vibration emission value during actual use of the power tool can differ
from the declared value depending on the ways in which the tool is used dependant on the

following examples and other variations on how the tool is used:

How the tool is used and the materials are cut or drilled.
The tool being in good condition and well maintained
The use the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles and any anti vibration accessories are used.

And the tool is being used as intended by its design and these instructions.

This tool may cause hand-arm vibration syndrome if its use is not adequately
managed

WARNING: To be accurate, an estimation of exposure level in the actual conditions of use

should also take account of all parts of the operating cycle such as the times when the tool
is switched off and when it is running idle but not actually doing the job. This may significantly
reduce the exposure level over the total working period.

Help to minimize your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep well lubricated (where
appropriate).
If the tool is to be used regularly then invest in anti vibration accessories.

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 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.

C1

Chain saw WG305E

NOTE: Chain should rotate freely and be free of

C1

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 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.

5. Double check the tension set by the automatic Chain

Tensioning 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).

completely unscrew the Chain Tensioning Knob (11)
or turn the knob around three full turns in a counter­clockwise direction, then retighten the Chain Tensioning
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.
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).

Chain saw WG305E

OPERATION

F

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 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

J

body (See Fig. J).

Chain saw WG305E

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.

BAR MAINTENANCE

N

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.

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

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.

O

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 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. 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.

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
