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 includ-
ing bar and chain are installed properly.

STARTING THE ENGINE
1. Fill fuel and chain oil tanks respectively, and tighten

the caps securely.

2. Continuously push the priming bulb until fuel comes

in the bulb.

3. Set the switch to “I” position.

4. Pull out the choke knob to the second-stage position.

The choke will close and the throttle lever will then
be set in the starting position.

When restarting immediately after stopping the en-
gine, set the Choke knob in the first-stage position
(choke open and throttle lever in the starting posi-
tion).
Once the choke knob has been pulled out, it will not
return to the operating position even if you press
down on it with your finger. When you wish to return
the choke knob to the operating position, pull out
the throttle lever instead.

5. While holding the saw unit securely on the ground,

pull the starter rope vigorously.

Do not start the engine while the chain saw hangs in
one hand. The saw chain may touch your body. This
in very dangerous.

6. When engine has ignited, first push in the choke knob

to the first-stage position and then pull the starter
again to start the engine.

7. Allow the engine to warm up with the throttle lever

pulled slightly.

NOTE

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
screwdriver in the hole on bottom of the clutch side.
Adjust according to your work conditions.

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.
