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.

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

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.

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.
