tank cap (22).
2. Fill the tank to 80% capacity
with chain oil.

Starting the chainsaw

WARNING. Do not start the motor whilst the saw hangs
from one hand. This is very dangerous as the chain may
come in contact with your body.
1. Fill the fuel and oil tanks
respectively and tighten the
caps securely.
2. Set the on/off switch (18) to
On (the I position). Make sure
the brake is ON when starting
for safety, by pushing the front
guard forward.
3. When the machine is cold first
pull out the choke control (18)
to the CHOKE position. (Fully
withdrawn).
Note.
Once the choke control
has been pulled out, it cannot be
pushed back to the run position.
4. Depress the priming bulb (29)
6 times or when the bulb is full
of fuel.
Note. This is not required if
engine is warm or is being
restarted.
It returns automatically when the
trigger switch is operated.
5. Hold the chainsaw securely on
the ground and pull vigorously
on the recoil starter (13).
Repeat (at least 15 times) until
the engine "kicks" (attempts
to start).
6. With the lock off switch (20)
held depressed slightly pull on
the trigger switch (19) and then
release it. The choke control will
click back one position.
7. Pull the recoil starter (13)
again and restart the engine.
Allow the engine to warm up.
8. When the engine is warm first
depress the lock off switch
then pull fully on the trigger
switch for a short burst. The choke control will fully retract
to the RUN position, your chainsaw is now ready for use.
9. When restarting the engine when it is still warm, set the
choke control to the START
position. Hold the chainsaw
securely on the ground and
pull vigorously on the recoil starter (13). Allow the
engine to run for a few moments with the trigger switch
pulled slightly.
10. When the engine is fully
warm, pull on the trigger
switch. The choke control will
fully retract to the RUN position.
