STARTING AND STOPPING
Starting and stopping
Cold engine
Starting: The chain brake must be engaged when the chain
saw is started. Activate the brake by moving the front hand
guard forwards.
Ignition; choke: Set the choke control in the choke position.
This should automatically set the stop switch to the start
position.
Start throttle: The correct choke/start throttle setting is
obtained by moving the control to the choke position.
Primer bulb: If the machine is fitted with an air purge (A):
Press the air purge repeatedly until fuel begins to fill the bulb.
The bulb need not be completely filled.
Decompression valve: If the machine is fitted with a
decompression valve (B): Press the valve to reduce the
pressure in the cylinder and make starting easier. You should
always use the decompression valve when starting the
machine. Once the machine has started the valve will
automatically return to its original setting.
Warm engine
Use the same procedure as for starting a cold engine but
without setting the choke control in the choke position. The
correct choke/start throttle setting is obtained by moving the
choke control to the choke position and then pushing it in
again.
Starting
Grip the front handle with your left hand. Hold the chain saw
on the ground by placing your right foot through the rear
handle. Pull the starter handle with your right hand and pull
out the starter cord slowly until you feel a resistance (as the
starter pawls engage) then pull firmly and rapidly. Never twist
the starter cord around your hand.
CAUTION! Do not pull the starter cord all the way out and do
not let go of the starter handle when the cord is fully extended.
This can damage the machine.
Push in the choke control as soon as the engine fires and
keep pulling until the engine starts. When the engine starts,
quickly apply full throttle; the throttle start lock will
automatically disengage.
As the chain brake is still engaged the speed of the engine
must be set to idling as soon as possible, this is achieved by
quickly disengaging the throttle lock. This prevents
unnecessary wear to the clutch, clutch drum and brake band.
!
WARNING! Note the following before
starting:
The chain brake must be engaged when the
chain saw is started to reduce the chance of
contact with the moving chain during
starting.
Never start a chain saw unless the bar, chain
and all covers are fitted correctly. Otherwise
the clutch can come loose and cause
personal injuries.
Place the machine on firm ground. Make
sure you have a secure footing and that the
chain cannot touch anything.
Keep people and animals well away from the
working area.
