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.

Fitting the starter
• To fit the starter, first pull out the starter cord and place
the starter in position against the crankcase. Then

engages with the pawls.

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.
