4. Make a felling cut from the opposite side of
the notch and at a level slightly higher than the
bottom of the notch.
NOTE: When you fell a tree, be sure to warn
neighboring 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. Espe-
cially 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.
A LOG LYING ON THE GROUND
Saw down halfway,
then roll the log over
and cut from the oppo-
site 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 bottom.
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 fin-
ish by sawing from the opposite side.
NOTE: be alert to the springing back of a cut
limb.
PRUNING OF STAND-
ING TREE
Cut up from the bot-
tom, finish down from
the top.
NOTE:
do not use an unstable foothold or lad-
der. Do not overreach. Do not cut above shoul-
der height. Always use both your hand to hold
the saw.
MAINTENANCE
WARNING:
Before cleaning inspecting or re-
pairing the unit, make sure that the engine has
stopped and is cool. Disconnect the spark plug
to prevent accidental starting.
MAINTENANCE AFTER EACH USE
1. Air filter. Dust on the cleaner surface can
be removed by tapping a corner of the clean-
er against a hard surface. To clean dirt in the
meshes, split the cleaner into halves and brush
in gasoline. When using compressed air, blow
from the inside. To assemble the cleaner halves,
press the rim until it clicks.
NOTE: when installing the main filter, make sure
that the grooves on the filter edge are correctly
fit with the projections on the cylinder cover.
2. Oiling port.
Dismount the guide bar and
check the oiling port for clogging.
3. Guide bar.
When the guide bar is dismount-
ed, remove sawdust in the bar groove and the
oiling port. Grease the nose sprocket from the
feeding port on the tip of the bar.
4. Others. Check for fuel leakage and loose fas-
tenings and damage to major parts, specially
handle joints and guide bar mounting. If any
defects are found, make sure to have them re-
paired before operating the saw again.
PERIODICAL SERVICE POINTS
1. Cylinder fins. Dust clogging between the cyl-
inder fins will cause overheating of the engine.
Periodically check and clean the cylinder fins
after removing the air cleaner and the cylinder
cover. When installing the cylinder cover, make
sure that switch wires and grommets are posi-
tioned correctly in place.
NOTE: be sure to block the air intake hole.
2. Fuel Filter.
a) Using a wire hook, take cut the filter from the
filter point.
b) Disassemble the filter and wash with gaso-
line, or replace with a new one if needed.
NOTE: After removing the filter, use a pinch to
hold the end of the suction pipe. When assem-
bling the filter, take care not to allow filter fi-
bers or dust inside the suction pipe.
3. Oil Tank.
With a wire hook, take out the oil
filter through the filter port and clean in gaso-
