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
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. (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 (12 inches) 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.
