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
Normal start
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.

(G2500 OPS)
Move the select lever to the machine back side

indicated by label until it is stopped, and then set
this lever to the recoil start mode.

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.

One-push-start
(G2500 OPS only)

Use One-push-start after performing warming-up by

Recoil Start in the status where the machine body is
securely fixed. You can not use OPS when the engine
is cold.

The starting performance of the engine depends on

the adjustment of the engine. Ask the distributor to
adjust the engine if possible.

Be careful not to set OPS in motion except when

starting the engine. If so, it may lead to serious injury.

1. Move the select lever to the front side of the machine

body indicated by label until it is stopped, and set
this lever to the One-push-start mode.

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.
