MAINTENANCE
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
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.
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.
