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.
Check that the chain catcher is not damaged and is firmly
attached to the body of the chain saw. (84)
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. (85)
Start the engine and make sure the engine stops when
you move the stop switch to the stop setting. (13)
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine. (86)
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
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
Replacing the starter cord
Loosen the screws that hold the starter against the
crankcase and remove the starter. (87)
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. (88)
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. (89)
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and
turn the starter pulley about 2 turns clockwise.
Note! Check that the pulley can be turned at least a
further 1/2 turn when the starter cord is pulled all the
way out. Stretch the line with the handle. Move your
thumb and release the line. (90)
Replacing the return and drive springs
Recoil spring (A) (91)
Lift up the starter pulley. See instructions under the
heading Changing a broken or worn starter cord.
Remember that the recoil spring is coiled under
tension in the starter housing.
Remove the cassette with the recoil spring from the
Lubricate the recoil spring with light oil. Fit the
cassette with recoil spring in the starter. Fit the starter
pulley and tension the recoil spring.
Fitting the starter
To fit the starter, first pull out the starter cord and
place the starter in position against the crankcase.
Then slowly release the starter cord so that the pulley
engages with the pawls.
Fit and tighten the screws that hold the starter.
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
Care must be exercised when replacing
the return spring or the starter cord.
