MAINTENANCE
32 – English
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.
Remove the clip in the centre of the pulley. Remove the
spacer and the pulley. Insert and fasten a new starter cord
onto the pulley. Wind approx. 3 turns of the starter cord
onto the pulley. Connect the pulley to the recoil spring so
that the spring engages in the pulley. Fit the spacer and
secure the pulley with the clip. 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.
!
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.
