CHECKING THE OIL SUPPLY
Make sure to set up the bar and the chain when
checking the oil supply.
If not, the rotating parts may be exposed. It is very
dangerous.
After starting the engine, run the chain at medium speed
and see if chain oil is scattered off as shown in the fig-
ure.
The chain oil flow can be changed by inserting a screw-
driver in the hole on bottom of the clutch side. Adjust
according to your work conditions.
Note: The oil tank should become nearly empty by the time fuel is
used up. Be sure to refill the oil tank every time when refueling the
saw.
■
ADJUSTING THE CARBURETOR
The carburetor on your unit has been factory adjusted,
but may require fine tuning due to a change in operat-
ing conditions.
Before adjusting the carburetor, make sure that the pro-
vided air/fuel filters are clean and fresh and the fuel prop-
erly mixed.
When adjusting, take the following steps:
Note: Be sure to adjust the carburetor with the bar chain attached.
It is very dangerous to run a chainsaw that mounts
broken parts or lacks any parts.
Before starting engine, make sure that all the parts
including bar and chain are installed properly.

the caps securely.

the Choke knob in “START” position (choke open and throttle le-
ver in the starting position).
Note: Once the choke knob has been pulled out, it will not return
to “RUN” position even if you press down on it with your finger.
When you wish to return the choke knob to “RUN” position, pull
out the throttle lever instead.
5. While holding the saw unit securely on the ground,
pull the starter rope vigorously.
