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.
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.
Replacement of broken recoil and drive 
disc springs
Recoil spring (A)
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 
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 
injury.
Care must be exercised when replacing 
the return spring, starter cord or the 
drive disc spring. Wear protective 
glasses and protective gloves.
