contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.
Some examples of these chemicals are:

• Lead from lead-based paints;

• Crystalline silica from bricks and

cement and other masonry products
and

• Arsenic and chromium from

chemically-treated lumber.
Your risk from these exposures varies,
depending on how often you do this
type of work. To reduce your exposure
to these chemical:

• Work in a well ventilated area, and

• Work with approved safety

equipment, such as those dust masks

that are specially designed to filter

out microscopic particles.

WARNING: This product maybe

contains lead, phthalate or other
chemicals known to the State of
California to cause cancer, birth defects
and other reproductive harm. Please
wash your hands after use.

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 battery­operated (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, non­skid 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 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

98

Chain Saw ENChain Saw EN

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 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.

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.

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

FOR ALL DOUBLE-INSULATED
APPLIANCES

1) Replacement Parts.

When servicing use only identical replacement
parts.

2) Polarized Appliance Connections

To reduce the risk of electric shock, this
appliance has a polarized plug (one blade is
wider than the other) and will require the use
of a polarized extension cord. The appliance
plug will fit into a polarized extension cord
only one way. If the plug does not fit fully
into the extension cord, reverse the plug.
If the plug still does not fit, obtain a correct
polarized extension cord. A polarized
extension cord will require the use of a
polarized wall outlet. This plug will fit into the
polarized wall outlet only one way. If the plug
does not fit fully into the wall outlet, reverse
the plug. If the plug still does not fit, contact a
qualified electrician to install the proper wall
outlet. Do not change the equipment plug,
extension cord receptacle, or extension cord
plug in any way.
Keep the pole chain saw a sufficient distance
away from electrical power lines.

INSTRUCTIONS CONCERNING THE
PROPER TECHNIQUES FOR BASIC
FELLING, LIMBING, AND CROSS­CUTTING

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

The escape path should extend back and
diagonally to the rear of the expected line of
fall as illustrated in Figure M.
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 M. 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 M. 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 N. 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 O, it is cut from
the top (overbuck).

1312

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

roll or slide downhill after it is felled.
An escape path should be planned and
cleared as necessary before cuts are started.
