Carburetor anti-freeeze mechanism
Operating the chain saw in temperatures of 0~5°C at
times of high humidity may result in ice forming within the
carburetor, and this in turn may cause the output power
of the engine to be reduced or for the engine to fail to
operate smoothly.
This product has accordingly been designed with a
ventilation hatch the back of the air cleaner cover to allow
warm air to be supplied to the engine thereby preventing
icing from occurring.
Warning! Continuing to use the product in anti-freeze
mode even when temperatures have risen and returned
to normal may result in the engine failing to start properly
or in the engine failing to operate at its normal speed, and
for this reason you should always be sure to return the
unit to normal operating mode if there is no danger of icing
occurring.
How to switch between operating modes (Fig. L)
1. Flip the engine switch to turn off the engine.
2. Remove the air cleaner cover (18) and remove the
screen (20) on the back of the air cleaner cover.
3. Reattach the screen right side left so as to the
anti-icing (19) plate is on the right. Reinstall the cover.
(a) Normal operating mode
(b) Anti-freeze mode
Warning! Continuing to use the product in anti-freeze
mode even when temperatures have risen and returned to
mormal may result in the engine failing to start properly or
in the engine failing to operate at its mormal speed, and
for this reason you should always be sure to return the
unit to normal operating mode if there is no danger of icing
occurring.
Chain brake (Fig. M)
To release brake (21), pull up the front guard toward the
front handle till "click" sound is heard.

SAWING
Warning!
f It is not necessary to force the saw into the cut.
Apply only light pressure while running the
engine at full throttle.
f 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 (Fig. N)
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 break operation before each usage
by running the saw at full 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
when operating the saw. Removal of the safety devices,
inadequate maintenance, or incorrect replacement of the
bar or chain may increase the risk of serious personal
injury due to kickback.
Felling a tree
f Decide the felling direction considering the wind,
lean of the tree, location of heavy breaches, ease
of job after felling and other factors.
f While cleanig the area around the tree, arrange a
good foothold and retreat path.
f Make a notch cut one-third of the way into the
tree on the felling side.
f Make a felling cut from the from the opposite side
of the notch and at a level slightly higher than the
bottom of the notch.
Warning! When you fell a tree, the sure to warn your
neighboring workers of the danger. (Fig. O)

Bucking and Limbing
Warning!
f Always ensure your foothold. Do not stand on the log.
f Be alert to the rolling over of a cut log. Especially
when working on a slope, stand on the uphill side of
the log.
f Follow the instrctions in "For Safe Operation" to
avoid kichback of the saw.
A log lying on the ground (Fig. P)
Saw down halfway, then roll the log over and cut from the
opposite side.
A Log hanging off the ground (Fig. Q)
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.
Cutting limb of Fallen Tree (Fig. R)
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.
