MAINTENANCE
Stop switch
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.
Muf
fl
er
Never use a machine that has a faulty muf
fl
er.
Regularly check that the muf
fl
er is securely attached to the
machine.
Some muf
fl
ers are equipped with a special spark arrestor
mesh. If your machine has this type of muf
fl
er, 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 muf
fl
er that is in poor condition.
Never use a muf
fl
er if the spark arrestor mesh is missing
or defective.
The muf
fl
er 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
fi
re
if directed against dry and combustible material.
A muf
fl
er equipped with a catalytic converter signi
fi
cantly
reduces the amount of hydrocarbons (HC), nitrogen oxides
(NO) and aldehydes in the exhaust fumes. Carbon monoxide
(CO), which is poisonous and odourless, is not however
reduced! Consequently, never work in an enclosed or badly
ventilated area. Good air circulation should always prevail
when working in snowy hollows, ravines or in con
fi
ned
conditions.
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.
•
Undo the screw in the centre of the pulley and remove the
pulley. Insert and fasten a new starter cord to the pulley.
Wind approx. 3 turns of the starter cord onto the pulley.
Connect the pulley to the recoil spring so that the end of
the spring engages in the pulley. Fit the screw in the
!
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.
