Make sure the vibration damping units are securely
attached to the engine unit and handle unit.

Stop switch

Start the engine and make sure the engine stops when
you move the stop switch to the stop setting.
Muffler
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine.
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.
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

Changing a broken or worn starter cord

• Loosen the screws that hold the starter against the
crankcase and remove the starter.
• 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.
!
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.
