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.

MAINTENANCE
• Remove the recoil spring by turning the starter over
and loosen the hooks, with the help of a screwdriver.

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.

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.
