than intended could result in a hazardous
situation.
13.
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 rm grip, with thumbs and
ngers 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
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.
14. Cut the wood in right direction.
15.
Before use the chain saw, be sure to
check the chain and bar in tension.
Don’t
use the chain saw if the chain and bar are
loose. Also conrm with that no abnormality
exists by actual test running.
16. Do not operate in rain.
17.
Switch o and remove the battery pack
when not in use, and before performing
maintenance or adjustments.
18. Pull out the battery pack before you change
or adjust the bar and chain Use only suitable
bar Oregon/180SDEA041 and chain Oregon
/91P062X.
19.
Never leave the machine unattended in
rooms with children.
20.

General using method
1.Use the chain saw only with secure footing.
2.Always hold the chain saw rmly with both
hands. Front grip with the left hand and
rear grip with the right hand. Fully grip both
handles at all times during operation. Never
operate chain saw using only one hand. Hold
the chain saw at the right-hand side of your
body.

blade to reach full speed before it makes
contact with the wood.
The proper techniques for basic felling,
limbing, and cross-cutting
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 notied 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 .
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.
Notching undercut
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls.
Make the lower horizontal notching cut rst. This
will help to avoid pinching either the saw chain
or the guide bar when the second notch is being
made.
Felling back cut
Make the felling back cut at least 1.97 in. higher
than the horizontal notching cut.
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 aluminum 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.
Limbing a tree
Limbing is removing the branches from a fallen
tree. When limbing leave larger lower limbs to
support the log o the ground. Remove the small
limbs in one cut.
Branches under tension should be cut from the
bottom up to avoid binding the chain saw.

Bucking a log
Bucking is cutting a log into lengths. It is
important to make sure your footing is rm 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
It is cut from the top (over buck).
When the log is supported on one end, cut 1/3
the diameter from the underside (under buck).
Then make the nished cut by over bucking to
meet the rst cut.
When the log is supported on both ends, cut
1/3 the diameter from the top (over buck). Then
make the nished cut by under bucking the lower
2/3 to meet the rst cut.
When bucking on a slope always stand on the
uphill side of the log,
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.
Maintenance and storage
WARNING!
Before performing any
repair work, always remove the battery
pack and wait until the cutting blade has
