STARTING AND STOPPING
Starting and stopping
A 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 web 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. (49)
Cold engine
Start position, 1 : Set the start/stop switch in the choke
position by pulling the red control outward - upward. (50)
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. (50)
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. (50)
Grip the front handle with your left hand. Hold the chain
saw on the ground by placing your right foot through the
rear handle. (51)
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. (50)
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. (50)
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. (50)
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. (51)
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). (50)
NB! 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! Pull the front hand guard towards the front
handle. The chain brake is now disengaged. Your saw
is ready for use.
| | engine's exhaust fumes, chain oil mist |
and dust fro m sawdus! 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. (52)
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.
(53)
NB! The start/stop switch automatically returns to run
position. To avoid involuntary start up, the spark plug cap
must always be removed from the spark plug when the
machine is unsupervised. (54)
