Maintenance

Checking and adjusting of throttle wire

Check that the engine responds to the throttle control and that the correct engine speed is achieved at full throttle.

If doubts arise, contact your service representative.

If adjustment is necessary, adjust the lower wire as follows:

1Loosen the clamping screw for the cable’s outer casing and move the throttle to the full throttle position.

2Check that the throttle wire is attached to the correct hole in the lower lever, see diagram.

3Pull 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:

1Release the clamping screw that secures the wire casing and set the choke control to maximum choke.

2Check that the throttle wire is attached to the upper lever, see diagram.

3Pull 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.

Replace the filter as follows:

1Open the engine cover.

2Move the hose clips away from the filter. Use a pair of flat pliers.

3Pull off the filter from the hose ends.

4Press the new filter into the ends of the hoses. If necessary apply liquid detergent to the ends of the filter to facilitate connection.

5Push the hose clips back on the filter and tighten.

Checking the fuel pump’s air filter

Check regularly that the fuel pump’s air filter is free from dirt.

The filter can when necessary be cleaned with a brush.

Checking the transmission’s air intake

Check that the transmission’s air intake in not blocked.

Remove the transmission cover and clean any grass cuttings from the transmission’s cooling fins if necessary.

Cooling is impaired if the air intakes are blocked or the transmission housing is dirty, this can result in damage to the transmission.
