Starting And Stopping - Husqvarna TrioBrake 455e Series 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.
Starting
The chain brake must be engaged when the chain saw is
started. Activate the brake by moving the front hand guard
forwards. (45)
Cold engine
Stopswitch; choke (A): Set the choke control in the
choke position by pull the choke control outwards. This
automatically sets the stop switch to the start position.
(46)
Air purge (B): Press the air purge diaphragm repeatedly
until fuel fills the diaphragm (at least 6 times). The
diaphragm need not be completely filled. (46)
Decompression valve (C): The machine is fitted with a
decompression valve. 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. (47)
Pull the starter handle (D): 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 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. (49)
Warm engine
Ignition; choke (A): The correct choke/start throttle
setting for warm starting is obtained by moving the choke
control to the choke position and then pushing it in again.
(50)
Start throttle: The correct choke/start throttle setting is
obtained by moving the control as stated above.

STARTING AND STOPPING
Air purge (B): Press the air purge repeatedly (at least 6
times) 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.
Pull the starter handle (D): 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.
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 disengaging the throttle lock. Disengagement is done
by gently touching on the throttle trigger. This prevents
unnecessary wear to the clutch, clutch drum and brake
band. (9) Allow the machine to idle a few seconds before
giving full throttle.
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.
Note! Reactivate the chain brake by pushing the front
hand guard back towards the front handle. The chain
saw is now ready for use. (40)
WARNING! Long term inhalation of the
!
engine's exhaust fumes, chain oil mist
and dust from sawdust can represent a
health risk.
• Never start a chain saw unless the bar, chain and all
covers are fitted correctly. See instructions under the
heading Assembly. Without a bar and chain attached
to the chain saw the clutch can come loose and cause
serious injury.
• The chain brake should be activated when starting. Se
instructions under the heading Start and stop. Do not
drop start. This method is very dangerous because
you may lose control of the saw. (51)
• Never start the machine indoors. Exhaust fumes can
be dangerous if inhaled.
• Observe your surroundings and make sure that there
is no risk of people or animals coming into contact with
the cutting equipment.
• Always hold the saw with both hands. The right hand
should be on the rear handle, and the left hand on the
front handle. All people, whether right or left handed,
should use this grip. Use a firm grip with thumbs and
fingers encircling the chain saw handles.
Stopping
Stop the engine by pushing the start/stop switch down.
