9. Sawing
• Before proceeding to your job, read
"For Safe Operation" section It is
recommended to first practice
sawing easy logs. This also helps
you get accustomed to your unit.
• Always follow the safety
regulations. The chain saw must
only be used for cutting wood. It is
forbidden to cut other types of
material. Vibrations and kickback
vary with different materials and the
requirements of the safety
regulations would not be respected.
Do not use the chain saw as a lever
for lifting, moving or splitting
objects. Do not lock it over fixed
stands. It is forbidden to hitch tools
or applications to the P.t.o. that are
not specified by the manufacturer.
• It is not necessary to force the saw
into the cut. Apply only light
pressure while running the engine
at full throttle.
• When the saw chain is caught in the
cut, do not attempt to pull it out by
force, but use a wedge or a lever to
open the way.
■ GUARD AGAINST KICKBACK (F21)
• This saw is equipped with a chain
brake that will stop the chain in the
event of kickback if operating properly.
You must check the chain brake
operation before each usage by
running the saw at full the throttle for 1
- 2 seconds and pushing the front hand
guard forward. The chain should stop
immediately with the engine at full
speed. If the chain is slow to stop or
does not stop, replace the brake band
and clutch drum before use.
• It is extremely important that the chain
brake be checked for proper operation
before each use and that the chain be
sharp in order to maintain the kickback
safety level of this saw. Removal of the
safety devices, inadequate
maintenance, or incorrect replacement
of the bar or chain may increase the
risk ot serious personal injury due to
kickback.
WARNING
■ FELLING A TREE (F22)
1. Decide the felling direction considering
the wind, lean of the tree, location of
heavy branches, ease of job after
felling and other factors.
2. While clearing the area around the
tree, arrange a good foothold and
retreat path.
3. Make a notch cut one-third of the way
into the tree on the felling side.
4. Make a felling cut from the opposite
side of the notch and at a level slightly
higher than the bottom of the notch.
When you fell a tree, be sure to warn your
neighboring workers of the danger.
(1) Notch cut
(2) Felling cut
(3) Felling direction
Bucking and Limbing
• Always ensure your foothold. Do
not stand on the log.
• Be alert to the rolling over of a cut
log. Especially when working on a
slope, stand on the uphill side of the
log.
• Follow the instructions in "For Safe
Operation" to avoid kickback of the
saw.
Before starting work, check the direction
of bending force inside the log to be cut.
Always finish cutting from the opposite
side of bending direction to prevent the
guide bar from being caught in the cut.
A Log lying on the ground (F23)
Saw down halfway, then roll the log over
and cut from the opposite side.
A Log hanging off the ground (F24)
In area A, saw up from the bottom one-
third and finish by sawing down from the
top. In area B, saw down from the top
one-third and finish by sawing up from the
bottom.
