CAUTION
● When cutting off branches which touch the
ground, be careful that the guide bar does
not become bound by pressure.
● During the fi nal cutting stage, beware of
the log suddenly rolling.
3. Log cutting
When cutting a log positioned as shown in Fig.
27, fi rst cut in about one third of the way from
below, then cut down all the way from above.
When cutting a log that straddles a hollow as
shown in Fig. 28, fi rst cut in about two thirds
of the way from above, then cut upward from
below.
CAUTION
● Ensure the guide bar does not become
bound in the log by pressure.
● When working on inclined ground, be sure
to stand on the uphill side of the log. If you
stand on the downhill side, the cut-off log
may roll toward you.
4. Felling trees
(1) Undercut ( as shown in Fig. 29):
Make undercut facing the direction in which you
want the tree to fall.
The depth of the undercut should be 1/3 of the
tree's diameter. Never fell trees without proper
undercut.
(2) Back cut ( as shown in Fig. 29):
Make a backcut about 2" (5 cm) above and
parallel to the horizontal undercut.
If the chain becomes entangled during cutting,
stop the saw and use wedges to free it. Do not
cut thorough the tree.

CAUTION
● Trees should not be felled in a manner that
would endanger any person, strike any
utility line or cause any property damage.
● Be sure to stand on the uphill side of the
terrain as the tree is likely to roll or slide
downhill after it is felled.
Precaution for cutting work
For large-scale operation or non-stop work
To protect the motor and electronics contained
in this unit, if it is exposed to high temperature,
this is signaled by a fl ashing LED light.
If you cut or push forcibly with a high load or
non-stop, the motor and electronics will heat up
and the LED light will fl ash.
NOTE
○ If the LED light fl ashes, stop using and please
allow the unit to cool suffi ciently. If you continue
to use it, the unit may sustain damage.
○ In addition, if you work non-stop, when
replacing the battery, please allow the unit to
cool down for at least 15 minutes.
○ In addition, when work is interrupted, if the LED
light fl ashes when you turn the switch back on,
this means the unit has not cooled suffi ciently,
so please allow longer downtime before
switching back on.
Gripping/pushing force of chain saw
Always grip the chain saw securely.
In addition, do not force the chain saw more
than necessary. When cutting, additional force
exerted on the chain saw will not accelerate
the cutting speed. This will strain the motor,
impair the performance, and damage or cause
malfunction of the motor or guide bar.
Use the unit in the range where the saw chain is
at a reasonable speed.
In particular, when the saw chain stops
(becomes jammed) due to the excessive force,
it may cause an injury or failure of the unit.
