The chain brake must be engaged when the chain saw is 
started. Activate the brake by moving the front hand guard 
forwards.

Start position (1): Set the start/stop switch in the choke 
position by pulling the red control outward - upward.

Decompression valve (2): Press the valve to reduce the 
pressure in the cylinder and make starting easier. Once 
the machine has started the valve will automatically return 
to its original setting.

Air purge (3): Press the air purge diaphragm repeatedly 
until fuel begins to fill the diaphragm (about 6 times). The 
diaphragm need not be completely filled.

Grip the front handle with your left hand. Put your right 
foot into the boot grip through the lower section of the rear 
handle pressing the machine against the ground.

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 until the 
engine fires.

Push down the red choke control as soon as the engine 
fires which can be heard through a "puff" sound.  Keep on 
pulling the cord powerfully until the engine starts.

Start position (1): Set the start/stop switch in the choke 
position by pulling the red control outward - upward. Then 
immediately press down on the start/stop switch to attain 
start throttle setting.

Decompression valve (2): Press the valve to reduce the 
pressure in the cylinder and make starting easier. Once 
the machine has started the valve will automatically return 
to its original setting.

Air purge (3): Press the air purge diaphragm repeatedly 
until fuel begins to fill the diaphragm (about 6 times). The 
diaphragm need not be completely filled.

Grip the front handle with your left hand. Put your right 
foot into the boot grip through the lower section of the rear 
handle pressing the machine against the ground.

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 until the 
engine fires.

NOTE! 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.

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.
