Fit a guard to the bar before transporting the chain
saw or carrying it for any distance.
7 When you put the chain saw on the ground, lock the
saw chain using the chain brake and ensure you have
a constant view of the machine. Switch the engine off
before leaving your chain saw for any length of time.
General rules
1 If you understand what kickback is and how it happens
then you can reduce or eliminate the element of
surprise. By being prepared you reduce the risk.
Kickback is usually quite mild, but it can sometimes be
very sudden and violent.
2 Always hold the chain saw firmly with your right hand
on the rear handle and your left hand on the front
handle. Wrap your fingers and thumbs around the
handles. You should use this grip whether you are
right-handed or left-handed. This grip minimizes the
effect of kickback and lets you keep the chain saw
under control.
Do not let go of the handles!
3 Most kickback accidents happen during limbing. Make
sure you are standing firmly and that there is nothing
in the way that might make you trip or lose your
balance.
Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.
Have control over the workpiece. If the pieces you
intend to cut are small and light, they can jam in the
saw chain and be thrown towards you. Even if this
does not need to be a danger, you may be surprised
and lose control of the saw. Never saw stacked logs or
branches without first separating them. Only saw one
log or one piece at a time. Remove the cut pieces to
keep your working area safe.
4 Never use the chain saw above shoulder height
and avoid cutting with the tip of the bar. Never use
the chain saw one-handed!
5 In order to keep control of your saw, always maintain
a firm foothold. Never work on a ladder, in a tree or on
any other insecure support.
6 Always use a fast cutting speed, i.e. full throttle.
7 Take great care when you cut with the top edge of the
bar, i.e. when cutting from the underside of the object.
This is known as cutting with a pushing chain. The
chain tries to push the chain saw back towards the
!
WARNING! Sometimes chips get stuck in
the clutch cover causing the chain to
jam. Always stop the engine before
cleaning.
STARTING AND STOPPING
English – 21
1153137-95 Rev.2 2009-12-29
Starting and stopping
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
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.
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. 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
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.
Start throttle: The correct choke/start throttle setting is
obtained by moving the control as stated above.
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.
!
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 wrap the starter cord around your
hand.
