as dust mask, non-skid safety shoes,
hard hat or hearing protection used
appropriately will reduce personal injuries.
• Prevent unintentional starting. Ensure
the switch is in the off position before
connecting to power source and/or
battery pack and when 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.
• 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.
• Do not over-reach. Keep proper
footing and balance at all times.
This
enables better control of the power tool in
unexpected situations.
• 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.
• 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.
• Use only Masterforce Batteries: BAB726 or
other BAB series
.
• Use only Masterforce Charger: CAB809 or
other CAB series.
POWER TOOL USE AND CARE
• 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.
• 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.
• Disconnect the plug from the power
source and/or the battery pack from

Such preventive
safety measures reduce the risk of starting
the power tool accidentally.
Page 5
• 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.
• 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.
• Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
• 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.
BATTERY TOOL USE AND CARE
• Recharge only with the charger
specied by the manufacturer.
A charger
that is suitable for one type of battery pack
may create a risk of fire when used with
another battery pack.
• Use power tools only with specifically
designated battery packs.
Use of any
other battery packs may create a risk of
injury and fire.
• When battery pack is not in use, keep
it away from other metal objects like
paper clips, coins, keys, nails, screws,
or other small metal objects that can
make a connection from one terminal
to another.
Shorting the battery terminals
together may cause burns or fire.
• Under abusive conditions, liquid may
be ejected from the battery; avoid
contact. If contact accidentally occurs,
flush with plenty of soap and water. If
liquid contacts eyes, immediately seek
medical help.
Liquid ejected from the
battery may cause irritation or burns.
SAFETY INSTRUCTIONS
SERVICE
• 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.
CHAINSAW SAFETY
WARNINGS
• Keep all parts of the body away from
the saw chain when the chainsaw
is operating. Before you start the
chainsaw, make sure the saw chain is
not in contact with anything.
A moment
of inattention while operating chainsaws
may cause entanglement of your clothing
or body with the saw chain.
• Hold the power tool by insulated
gripping surfaces only, because the
saw chain may contact hidden wiring.
Saw chains contacting a “live” wire may
make exposed metal parts of the power
tool “live” and could give the operator an
electric shock.
• Always hold the chainsaw with your
right hand at the rear handle and your
left hand at the front handle.
Holding
the chainsaw with a reversed hand
configuration increases the risk of personal
injury and should never be done.
• Wear safety glasses and hearing
protection. Further protective product
for head, hands, legs and feet is
recommended.
Adequate protective
clothing will reduce personal injury from
flying debris or accidental contact with the
saw chain.
• Do not operate a chainsaw in a tree.
Operation of a chainsaw while up in a tree
may result in personal injury.
• Always keep proper footing and operate
the chainsaw only when standing on
xed, secure and level surface.
Slippery
or unstable surfaces such as ladders may
cause loss of balance or control of the
chainsaw.
• When cutting a limb that is under
tension, be alert of spring back.
When
the tension in the wood is released, the
spring loaded limb may strike the operator
Page 6
SAFETY INSTRUCTIONS
and/or throw the chainsaw out of control.
• 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.
• Carry the chainsaw by the front
handle with the chainsaw switched
off and away from your body. When
transporting or storing the chainsaw,
always fit the guide bar cover.
Proper
handling of the chainsaw will reduce the
likelihood of accidental contact with the
moving saw chain.
• Follow instructions for lubricating,
chain tensioning and changing
accessories.
Improperly tensioned or
lubricated chain may either break or
increase the chance for kickback.
• Keep handles dry, clean, and free from
oil and grease.
Greasy, oily handles are
slippery, causing loss of control.
• Cut wood only. Do not use chainsaw for
purposes not intended. For example:
do not use chainsaw for cutting
plastic, masonry or non-wood building
materials.
Use of the chainsaw for
operations other than intended could result
in a hazardous situation.
PREVENT OPERATOR
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 chainsaw 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 chainsaw
handles, with both hands on the saw
and your body and arm positioned 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 chainsaw.
• Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chainsaw in unexpected
situations.
• Only use replacement bars and chains
specied 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.

2. Hit utility lines. If the tree touches
utility lines, immediately tell the utility
company.
3. Cause losses in property.
• The user is not in the danger area (B), for
example, the downhill side of the area.
• The escape paths (C) that extend back and
diagonally behind the felling direction (A)
are clear. The felling direction is controlled
by
1. The natural lean of the tree.
2. The location of larger branches.
3. The wind direction.
• Ensure there is no dirt, stones, loose bark,
nails, and staples on the tree.
1. Make a lower level notching cut (D). Make
sure that this cut is
• 1/3 wide of the diameter of the tree.
• Perpendicular to the felling direction.
CAUTION
The level notching
cut helps prevent pinching of the saw chain
or the guide bar when you make the second
notch.
2. Make the felling cut no less than 2 in. (50
mm) and higher than the level notching cut.
Make sure that this cut
• Is parallel to the level notching cut.
• Keeps sufcient wood to become a hinge
(F) which prevents the tree from twisting
and felling in the wrong direction.
When the felling cut (E) gets near the hinge
(F), the tree falls. Stop the felling cut if the
tree
• Does not fall in the correct direction or
• Moves backwards, causing the cutting bar
and chain to become stuck in the cut.
3. Use felling wedge to open the cut and let
the tree fall in the correct direction.
4. When the tree starts to fall,
• Remove the chainsaw from the cut.
• Stop the machine.
• Put the machine down.
• Move away from the tree via the escape
path (C). Always keep watching the tree
to see it's direction of fall, be careful with
overhead branches and your footing.
LIMB A TREE
Limbing is the removal of the branches from a
fallen tree.
• Keep the larger lower branches to hold the
log off the ground (H).
• Remove the small limbs (G) in one cut.
• Limb the branches with tension from the
bottom to top.
• Keep the larger lower branches as a
support until the log is limbed.
