Adjusting the throttle wire
The throttle cable may need to be adjusted, if the engine does
not respond as it should when accelerating, if it produces
black smoke or maximum revs are not reached.
If adjustment is necessary, adjust the lower wire as follows:
1 Loosen the clamping screw for the cable's outer casing
and move the throttle to the full throttle position.
2 Check that the throttle wire is attached to the correct hole
in the lower lever, see diagram.
3 Pull the throttle wire casing to the far left and tighten the
clamping screw.
Checking and adjusting the choke
wire
If the engine is producing black smoke or is difficult to start
then the choke wire (upper wire) may be incorrectly adjusted.
If doubts arise, contact your service representative.
If it is necessary to adjust the choke, proceed as follows:
1 Release the clamping screw that secures the wire casing
and set the choke control to maximum choke.
2 Check that the throttle wire is attached to the upper lever,
see diagram.
3 Pull the choke wire casing to the far right and tighten the
clamping screw.
Replacement of fuel filter
Replace the fuel filter every 100 running hours (once per
season) or more frequently if it is clogged.
Maintenance
Replace the filter as follows:
1 Open the engine cover.
2 Move the hose clips away from the filter. Use a pair of flat
pliers.
3 Pull off the filter from the hose ends.
4 Press the new filter into the ends of the hoses. If
necessary apply liquid detergent to the ends of the filter to
facilitate connection.
5 Push the hose clips back on the filter and tighten.
Replacing the air filter
If the engine seems to lack power or does not run smoothly
this may be because the air filter is clogged. It is therefore
important to replace the air filter at regular intervals (see
Maintenance/Maintenance Schedule for the correct service
interval).
Replace the air filter as follows:
1 Open the engine cover.
2 Remove the cover.
3 Pull up the filter at one edge and lift it out.
4 Lift out the air filter cartridge from the fan housing.
Replace the air filter cartridge, if clogged with dirt.
5 Clean the filter by knocking the filter against a flat surface.
Never use solvent with petroleum, for example, kerosene,
or compressed air to clean the filter.
IMPORTANT!
Do not use compressed air or solvent with petroleum to
clean the cartridge.
The filters must not be oiled. They must be fitted dry.
6 Carefully clean the fan housing so that dirt does not fall
down into the carburettor.
7 Push the filter cartridge in place.
