MAINTENANCE
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 
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.
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.
A muffler equipped with a catalytic converter significantly 
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 confined 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 centre of the pulley. Insert the starter 
cord through the hole in the starter housing and the starter 
handle. Make a secure knot in the end of the starter cord.
!
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.
