Checking the brake trigger
Place the chain saw on firm ground and start it. Make sure
the chain does not touch the ground or any other object.
See the instructions under the heading Start and stop.
(89)
Grasp the chain saw firmly, wrapping your fingers and
thumbs around the handles. (51)
Apply full throttle and activate the chain brake by tilting
your left wrist forward onto the front hand guard. Do not
let go of the front handle. The chain should stop
immediately. (46)
Throttle lockout
•
Make sure the throttle control is locked at the idle
setting when the throttle lockout is released. (90)
•
Press the throttle lockout and make sure it returns to
its original position when you release it. (91)
•
Check that the throttle trigger and throttle lockout
move freely and that the return springs work properly.
(92)
•
Start the chain saw and apply full throttle. Release the
throttle control and check that the chain stops and
remains stationary. If the chain rotates when the
throttle control is in the idle position you should check
the carburetor idle adjustment.
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw. (93)
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks. (12)
Vibration damping system
Regularly check the vibration damping units for cracks or
deformation. Make sure the vibration damping units are
securely attached to the engine unit and handle unit. (94)

MAINTENANCE
Stop switch
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting. (47)
CAUTION! The start/stop switch automatically returns to
run position. In order to prevent unintentional starting, the
spark plug cap must be removed from the spark plug
when assembling, checking and/or performing
maintenance.
Muffler
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine. (95)
Some mufflers are equipped with a special spark arrestor
screen. If your machine has this type of muffler, you
should clean the screen at least once a week. This is best
done with a wire brush. A blocked screen will cause the
engine to overheat and may lead to serious damage.
Note! The screen must be replaced if it is damaged. If the
screen is blocked the machine will overheat and this will
cause damage to the cylinder and piston. Never use a
machine with a muffler that is in poor condition. Never
use a muffler if the spark arrestor screen is missing
or defective. (14)
The muffler is designed to reduce the noise level and to
direct the exhaust gases away from the operator. The
exhaust gases are hot and can contain sparks, which may
cause fire if directed against dry and combustible
material.
Starter
!
Replacing the starter cord
•
Loosen the screws that hold the starter against the
crankcase and remove the starter. (96)
WARNING! When the recoil spring is
wound up in the starter housing it is
under tension and can, if handled
carelessly, pop out and cause personal
injury.
Care must be exercised when replacing
the return spring or the starter cord.
Wear protective glasses and protective
gloves.
