Care must be exercised when replacing the return spring or the starter cord. 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.

Changing a broken recoil spring

•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.

•Lubricate the recoil spring with light oil. Fit the cassette with recoil spring in the starter. Fit the starter pulley and tension the recoil spring.

Fitting the starter

•To fit the starter, first pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.

•Fit and tighten the screws that hold the starter.
