Notch cut
Felling cut
Felling direction
This saw is equipped with a chain
brake that will stop the chain in the
event of kickback if operating prop-
erly. You must check the chain brake
operation before each usage by run-
ning the saw at full the throttle for I -
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, re-
place 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 main-
tain the kickback safety level of this
saw. Removal of the safety devices,
inadequate maintenance, or incor-
rect replacement of the bar or chain
may increase the risk ot serious per-
sonal injury due to kickback.
FELLING A TREE
1. Decide the felling direction considering the wind,
lean of the tree, location of heavy branches, ease of
completing the task 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 neigh-
boring workers of the danger.
Bucking and Limbing
Always ensure your foothold. Do not stand
on the log.
Be alert to the rolling over of a cut log. Es-
pecially when working on a slope, stand
on the uphill side of the log.
Follow the instructions in “For Safe Opera-
tion” 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 the bending direction to prevent
the guide bar from being caught in the cut.
