safety, set the chain brake when the saw is not in use.
iii. In the event that the ignition switch will not stop the saw, pull the choke lever
out to the fully extended position “Full choke” and engage the chain brake to
stop the engine. If the ignition switch will not stop the saw when set to the “Stop”
position, have the ignition switch repaired before using the chainsaw again to
prevent unsafe conditions or serious injury.
Note: After using the saw, always relieve tank pressure by loosening then re-tight-
ening the chain lubricant and fuel caps. Allow the engine to cool before storing.
ADJUSTING IDLE SPEED
See Figure 15.
If the engine starts, runs and accelerates, but will not idle, turn the idle speed screw
“T” clockwise to increase idle speed to 2600~3600 rpm.
If the chain turns at idle, turn the idle speed screw “T” counter clockwise to reduce
the idle RPM and stop the chain movement. If the saw chain still moves at idle
speed, contact an authorised service centre for adjustment and discontinue use
until the repair is made.
WARNING
THE SAW CHAIN SHOULD NEVER TURN AT IDLE. Serious personal injury may
result from the saw chain turning at idle.
PULL AND PUSH
See Figure 16.
The reaction force of the saw is always opposite to the direction the chain is moving.
The operator must be ready to control the PULL when cutting on the bottom edge of
the bar and the PUSH when cutting along the top edge.
Note: The chainsaw has been factory tested. It is normal to find some slight lubri-
cant residue on the saw.
KICKBACK PRECAUTIONS
See Figures 17-18.
Rotational kickback occurs when the moving chain contacts an object at the Kickback
Danger Zone of the guide bar. The result is a lightning-fast reverse reaction, which
kicks the guide bar up and back towards the operator. This reaction can cause loss of
control, which can result in serious injury.
