• 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.
• Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
• 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.
• Replace of the supply cord. If the supply cord is damaged, it must be replaced by
an electrician or a power tool repairer.
• 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.
• 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.
• Have your tool repaired by an electrician or a power tool repairer. This power tool
complies with relevant safety requirements. To avoid danger, electrical appliances
this may result in considerable damage to the user.

ADDITIONAL SAFETY INSTRUCTIONS FOR ELECTRIC
CHAINSAW
ADDITIONAL SAFETY INSTRUCTIONS FOR ELECTRIC
CHAINSAW (Cont.)
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
contacting anything. A moment of inattention while operating chainsaws may
cause entanglement of your clothing or body with the saw chain.
• Always hold the chainsaw with your right hand on the rear handle and your left
hand on the front handle. Holding the chainsaw with a reversed hand
• Wear safety glasses and hearing protection. Further protective equipment for
head, hands, legs and feet is recommended. Adequate protective clothing will
• 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
s such as ladders may
cause a loss of balance or control of the chainsaw.
• When cutting a limb that is under tension be alert for spring back. When the
operator 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
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 different than intended could result in a hazardous
situation.
Causes and operator prevention of kickback:
Kickbackmay 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 tolose 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:
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 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.
. 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.
Recommended:
• Use a residual current device with a tripping current of 30mA or less.
• During the cutting operation, the supply cord must be securely positioned to
prevent the cord from snagged on branches and the like.

Your chainsaw comes with one SDS system
for assembly and quick adjustment of chain tension. The
outside ring (part 1) adjusts the tension of the chain and
the inner screw adjusts the tension of the bar. Turn the
inner screw (part 2) of the SDS counter-clockwise to
open the chain over. (See Fig.3)
1). Unpack all parts carefully.
3). Spread the saw chain out with the cutting edges (A)
of the chain pointing in the direction of rotating. Slide
the saw chain into the slot around the chain bar. Ensure
chain is in correct running direction. (See Fig.4a, 4b)
4). Fit the chain bar onto the drive sprocket (11) and
fastening bolt then assemble safety guard. (See Fig. 5)
5). The chain is not yet tensioned. Tensioning the
chain applies as described under “Tensioning chain”.
After running the chainsaw around 1 hour, adjust the
chain tension to 2mm by applying 9N of torque.

• FELLING
Felling is a term for cutting down a tree. Small trees up to 6-7inches in diameter
are usually cut in a single cut. Large trees require notch cuts. Notch cutes
determine the direction the tree will fall.
Warning: An escape path (A) should be planned
and cleared as necessary. The path should extend
back and diagonally to the rear of the expected line
Caution: If felling a tree on a sloping ground, the chainsaw operator should
keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after
it's felled.
Note: Direction of fall (B) is controlled by the notching cut. Before any cuts are made,
consider the location of larger branches and natural lean of the tree to determinate
the direction the tree will fall.
Warning: Do not cut down a tree during high winds or if there is a danger to
property. Consult a tree professional. Do not cut a tree if there is a danger of striking a
power or telephone cable. Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D). Start making the upper notch cut (C) on
the tree facing the felling direction (E). Be sure you don't make the lower cut too
deep into the trunk. The notch (C) should be deep enough to create a hinge (F) of
the tree for as long as possible.
Warning: Never walk in front of a tree that has
been notched. Make the felling cut (D) from the
other side of the tree and 1.5 - 2.0 inches above
the edge of notch (C) (Fig.7)
Fig. 6
2). Place the chainsaw on any suitable flat surface.

12 13
Never saw completelythrough the trunk. Always leave a hinge (F). The hinge guides
the tree. If the trunk is completely cut through, control over the felling direction
is lost. Insert a wedge or felling lever in the cut (D) well before the tree becomes
unstable and starts to move. This will prevent the guide bar from binding in felling
cut if you have misjudged the falling direction. Make sure no bystanders have
entered the range of the falling tree before you push it over.
Warning:
animals, and/or obstacles.
1. Use wooden or plastic
wedges (A) to prevent
binding the bar or chain (B)
in the cut (Fig. 8)
2. When diameter of wood being cut is
greater than the bar length, make 2
cuts as shown (Fig. 9).
Warning: As the felling cut (D) gets close to the hinge (F), the tree should
begin to fall. Remove saw from cut, stop the engine, put the chainsaw down and
leave the area by the retreat path (Fig. 6).
• LIMBING
Limbing a tree is the process of removing
the branches from a fallen tree(Fig.10).
Do not remove supporting limbs (A).
Branches under tension should be cut
from the bottom up to avoid binding the
chainsaw.
Warning: Never cut tree limbs while standing on tree trunk.

•BUCKING
Bucking is cutting a fallen log into lengths. Make sure that you have a good footing
and stand uphill of the log when cutting on sloping ground. If possible, the log
should be supported so that the end to be cut off is not resting on the ground. If the
log is supported at both ends and you must cut in the middle, make a downward cut
halfway through the log and then make the undercut. This will prevent the log from
pinching the bar and chain. Be careful that the chain does not cut into the ground
when bucking as this causes rapid dulling of the chain.
1. Log supported along entire length: cut from bottom (under buck), being careful to
avoid cutting into the ground (Fig.11).
2. Log supported on 1 end proceed as if using a saw-horse: First, cut from bottom
(under buck) 1/3 diameter of log to avoid splintering. Second, cut from above (over
3. Log supported on both ends: First, over buck 1/3 diameter of log to avoid
Note: The best way to hold a log while bucking is to use a saw horse. When this
is not possible, the log should be raised and supported by limb stumps or by using
supporting logs. Be sure the log being cut is securely supported.
