Starting And Stopping - Husqvarna 439 Operator's Manual

Starting and stopping

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.
Never twist the starter cord around your
hand.
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.
Air purge: Press the air purge diaphragm repeatedly until
fuel begins to fill the diaphragm (about 6 times). The
diaphragm need not be completely filled.
Choke: Set the choke control in the choke position.
STARTING AND STOPPING
• Grip the front handle with your left hand. Put your right
foot on 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 starts.
• Push in the 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.
Warm engine
Use the same starting procedure as for a cold engine but
without setting the choke control in the choke position.
• Grip the front handle with your left hand. Put your right
foot on 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 starts.
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 pressing the throttle trigger once. This prevents
