Starting And Stopping - MTD 450E Operator's Manual

STARTING AND STOPPING
Starting and stopping
,#_ WARN NG! Note the following before
starting:
The chain brake must De 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 wrap the starter cord around your
hand.
Starting
The chain brake should be activated when starting the
chain saw. Activate the chain brake by pushing the front
hand guard forwards.
Cold engine
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 fills the diaphragm (at least 6 times). The
diaphragm need not be completely filled.
A
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 (4): 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 (5): As soon as the
engine fires which can be heard through a "puff" sound,
push down on the red choke control.
Pull the starter handle (6): Keep on pulling the cord
powerfully until the engine starts.
Warm engine
Start position (1): The correct choke/start throttle setting
for warm starting is obtained by initially moving the choke
control by pulling the red control outward - upwards.
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 fills the diaphragm (at least 6 times).The
diaphragm need not be completely filled.
Push down the red choke control (5): This inactivates
the choke, which is not needed when starting a warm
chain saw. However the movement of the start/stop switch
will have engaged a high idle, making warm starting
easier.
Pull the starter handle (6): 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 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. Allow the machine to idle a few seconds before
giving full throttle.
There is a simplified start reminder with illustrations to
describe each step on the rear edge of the saw (A).
