MAINTENANCE

Secure the starter cord around the cord pulley as illustrated. Tighten the fastening well and ensure that the free end is as short as possible. Secure the end of the starter cord in the starter handle.

Tensioning the recoil spring

Guide the cord through the cut-out in the periphery of the pulley and wind the cord 3 times clockwise around the centre of the starter pulley.

Now pull the starter handle and in doing so tension the spring. Repeat the procedure once more, but this time with four turns.

Note that the starter handle is drawn to its correct home position after tensioning the spring.

Check that the spring is not drawn to its end position by pulling out the starter line fully. Slow the starter pulley with your thumb and check that you can turn the pulley at least a further half turn.

Changing a broken recoil spring

Undo the bolt in the centre of the pulley and remove the pulley.

Bear in mind that the return spring lies tensioned in the starter housing.

Loosen the bolts holding the spring cassette.

Remove the recoil spring by turning the starter over and loosen the hooks, with the help of a screwdriver. The hooks hold the return spring assembly on the starter.

Lubricate the recoil spring with light oil. Fit the 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.

Tighten the screws.

Fuel system

General

Check that the fuel cap and its seal are not damaged.

Check the fuel hose. Replace when damaged.

Fuel filter

The fuel filter sits inside the fuel tank.

The fuel tank must be protected from contamination when filling. This reduces the risk of operating disturbances caused by blockage of the fuel filter located inside the tank.

The filter cannot be cleaned but must be replaced with a new filter when it is clogged. The filter should be changed at least once per year.
