PERIODICAL SERVICE POINTS
1. Cylinder fins
Dust clogging between the cylinder
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 positioned correctly
in place. (F29)
NOTE
Be sure to block the air intake hole.
2. Fuel filter
(a) Using a wire hook, take out the
filter from the filler port. (F30)
(1) Fuel filter
(b) Disassemble the filter and wash
with gasoline, or replace with new
one if needed.
NOTE
After removing the filter, use a pinch
to hold the end of the suction pipe.
When assembling 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 filler port and clean
in gasoline. When putting the filter
back into the tank, make sure that it
comes to the front right corner. Also
clean off dirt in the tank. (F31)
Remove the recoil starter
，
then clean
the air inlet of oil breather
。
(2) Oil filter
4. Spark plug (F32)
Clean the electrodes with a wire
brush and reset the gap to 0.65 mm
as necessary.
5. Sprocket (F33)
Check for cracks and for excessive
wear interfering with the chain drive.
If the wearing is found obviously,
replace it with new one. Never fit a
new chain on a worn sprocket, or a
worn chain on a new sprocket.
6. Front and Rear dampers
Replace if adhered part is peeled or
crack is observed on the rubber
part.
A Log lying on the ground (F21)
Saw down halfway, then roll the log over
and cut from the opposite side.
A Log hanging off the ground (F22)
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 (F23)
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 (F24)
Cut up from the bottom, finish down from
the top.
Do not use an unstable foothold or ladder.

Always use your both hands to grip the
saw.
WARNING
Before cleaning, inspecting or repairing
your unit, make sure that 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 cleaner
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. (F25)
To assemble the cleaner halves, press the
rim until it clicks.
NOTE
When installing the main filler, 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. (F26)

SAW CHAIN
WARNING
It is very important for smooth and safe
operation to keep the cutters always sharp.
Your cutters need to be sharpened when:
• Sawdust becomes powder-like.
• You need extra force to saw in.
• The cut way does not go straight.
• Vibration increases.
• Fuel consumption increases.
WARNING
Cutter setting standards: Be sure to wear safety
gloves. Before filing:
• Make sure the saw chain is held securely.
• Make sure the engine is stopped.
•
Use a round file of proper size for your
chain.
Chain type:
20BP
File size:
3/16 in 4.76mm
Place your file on the cutter and push straight
forward. Keep the file position as illustrated.
(F33)
After every cutter has been set, check the
depth gauge and file it to the proper level as
illustrated. (F34)
