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 spronging 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
repairing 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, splot the cleaner into halves and brush
in gasoline.
When using compressed air,
blow from the inside. To as-
semble 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 cylin-
der 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
fastenings and damage to major parts, spe-
cially handle joints and guide bar mounting. If
any defects are found, make sure to have them
repaired before operating the saw again.
PERIODICAL SERVICE POINTS
1. Cylinder fins. Dust clogging between the
cylinder fins will cause overheating of the en-
gine. Periodically check and clean the cylinder
fins after removing the air cleaner and the cyl-
inder cover. When installing the cylinder cover,
make sure that switch wires and grommets are
positioned 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 as-
sembling the filter, take care not to allow filter
fibers 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
gasoline. When putting the filter back into the
tank, make sure that air comes to the front
right corner. Also clean off dirt in the tank.
4. Spark plug. Clean
the electrodes with a
wire brush and reset
the gap to 0,65 mm as
necessary.
5. Sprocket. Check for cracks and for exces-
sive wear interfering with the chain drive. If
the wear is considerable, replace it with new
one. Never fit a new chain on a worn sprocket,
or a worn chain on a new sprocket.
SAW MAINTENANCE
SAW CHAIN
- It is very important for smooth and safe op-
eration to always keep the cutters sharp.
The cutters need to be sharpened when:
- Sawdust becomes powder-like.
- You need extra force to saw in.
- The cut path does not go straight.
- Vibration increases.
- Fuel consumption increases.
