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.
g) If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use of
3
Chain Saw WG303E WG303E.X
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
operator and/or throw the chain saw out
of control.
4
Chain Saw WG303E WG303E.X
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.

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
5
Chain Saw WG303E WG303E.X
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 first.
This will help to avoid pinching either the saw chin or
the guide bar when the second notch is being made.
3. Felling back cut
Make the felling back cut 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 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 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).
When the log is supported on one end, as illustrated
in Figure 4, cut 1/3 the diameter from the underside
(underbuck).Then make the finished cut by
overbucking 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). Then make the finished cut by
underbucking 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.
