Husqvarna 455 Manuel D’Utilisation

English

 – 21

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 (A): 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.

Air purge (B): Press the air purge repeatedly until fuel begins 
to fill the bulb. The bulb need not be completely filled.

Decompression valve (C): 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.

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.

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.

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.

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.
