season. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
Only use Bar and Chain Oil for bar and chain
lubrication.

STARTING
WARNING: The chain must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
To stop the engine move the ON/STOP
switch to the STOP position.
To start the engine hold the saw firmly on
the ground as illustrated. Make sure the
chain is free to turn without contacting any
object.
Hold saw firmly while pulling starter rope.
Use only 40 --- 45 cm of rope per pull.

IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the
full extent of the rope as this can cause the
rope to break. Do not let starter rope snap
back. Hold the handle and let the rope rewind
slowly.
For cold weather starting, start the unit at
FULL CHOKE; allow the engine to warm up
before squeezing the throttle trigger.
NOTE: Do not cut material with the choke/
fast idle lever at the FULL CHOKE position.
STARTING A COLD ENGINE (or
warm engine after running out of
fuel):
NOTE: In the following steps, when the
choke/fast idle lever is pulled out to the full
extent, the correct throttle setting for starting
is set automatically.
1. Move ON/STOP switch to the ON posi-
tion.
2. Pull the choke/fast idle lever out to the full
extent (to the FULL CHOKE position).
3. Pull starter rope sharply with your right
hand a maximum of 10 times. Then, pro-
ceed to the next step.
NOTE: If the engine sounds as if it is trying
to start before the 10th pull, stop pulling and
immediately proceed to the next step.
4. Push the choke/fast idle lever in to the
HALF CHOKE position.
5. Pull the starter rope sharply with your
right hand until the engine starts.

DIFFICULT STARTING (or starting a
flooded engine)
The engine may be flooded if it has not started
after 10 pulls. Flooded engines can be cleared
of excess fuel by following the warm engine
starting procedure listed above. Ensure the
ON/STOP switch is in the ON position. Starting
could require many pulls depending on how
badly unit is flooded. If engine still fails to start,
refer to the TROUBLESHOOTING TABLE.
