A log lying on the ground

Saw down halfway, then roll the log over and cut from
the opposite side.

A log hanging off the ground

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 bot-
tom.

Cutting the limbs of Fallen Tree

First check to which side the limb is bent. Then make
the initial cut from the bent side and finish by sawing
from the opposite side.

Be alert to the springing back of a cut limb.

Pruning of Standing Tree

Cut up from the bottom, finish down from the top.

• Do not use an unstable foothold or ladder.
• Do not overreach.
• Do not cut above shoulder height.
• Always use both your hands to hold the saw.

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 neighboring work-
ers 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. 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 the bending direction to prevent
the guide bar from being caught in the cut.
