Throttle lockout
• Make sure the throttle control is locked at the idle
setting when the throttle lockout is released. (100)
• Press the throttle lockout and make sure it returns to
its original position when you release it. (101)
• Check that the throttle trigger and throttle lockout
move freely and that the return springs work properly.
(102)
• 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 carburettor idle adjustment.
Chain catcher
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw. (103)
Right hand guard
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks. (11)
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.
(104)
Stop switch
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting. (59)
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. (105)
Some mufflers are equipped with a special spark arrestor
mesh. If your machine has this type of muffler, you should
clean the mesh at least once a week. This is best done
with a wire brush. A blocked mesh will cause the engine
to overheat and may lead to serious damage.
Note! The mesh must be replaced if it is damaged. If the
mesh 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 mesh is missing or
defective. (13)
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. (106)
• Pull out the cord approx. 30 cm and hook it into the
notch in the rim of the pulley. Release the recoil spring
by letting the pulley rotate slowly backwards. (107)
• Undo the bolt in the centre of the pulley and remove
the drive disc (A), drive disc spring (B) and the pulley
(C). Insert and secure a new starter cord in the starter
pulley. Wind approx. 3 turns of the starter cord on the
starter pulley. Fit the starter pulley so that the end of
the recoil spring (D) hooks into the starter pulley. Now
assemble the drive disc spring, drive disc and the bolt
in the centre of the pulley. Carry the starter cord
through the hole in the starter housing and the starter
handle. Tie a good knot on the starter cord. (108)
!
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.
