MAINTENANCE

Starter device

!WARNING!

•When the recoil spring is assembled in the starter housing, it is in tensioned position and can when treated carelessly, pop out and cause injuries.

•Always be careful, when changing the recoil spring or the starter cord. Always wear safety goggles for eye protection.

Changing a broken or worn starter cord

• Loosen the screws, that hold the starter device against the crankcase and remove the starter device.

•Pull out the cord approx. 30

cm and lift it up into the notch in the pulley. Zero-set 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 in the pulley. Wind approx. 3 turns of the starter cord on to the pulley. Assemble the starter pulley against the recoil spring, so the end of the spring engages to the pulley. Fit the screw in the centre of the pulley. Carry the starter cord through the hole in the starter housing and the starter handle. Make a knot on the starter cord.

Tensioning the recoil spring

•Lift the starter cord up in the notch on the starter pulley

and turn the starter pulley 2 turns clockwise.

NOTE! Check that the starter pulley can be turned at least half a turn, when the starter cord is entirely pulled out.

Changing the broken recoil spring

• Lift the starter pulley (see "Changing a broken or worn starter cord"). Bear in mind that the return spring sits under tension in a cassette.

• Dismantle the cassette with

the return spring from the starter.

• Lubricate the recoil spring with thin oil. Assemble the cassette with return spring in the starter. Fit the starter pulley and tension the return spring.

Starter device assembly

•Assemble the starter device, by pulling the starter cord out first, then place the

starter against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.

• Assemble and tighten the screws, which hold the starter.
