MAINTENANCE

Checking the Engine's Cooling Air Intake

Check that the engine’s cooling air intake is free from leaves, grass, and dirt.

If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage.

Checking and Adjusting

the Throttle Cable

Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle.

If doubts arise, contact the service workshop. If adjustments are necessary, they can be made as follows for the lower cable:

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 cable is mounted in the correct hole in the lower lever, see illustration.

3.Push the throttle cable’s outer casing as far to the left as possible and tighten the clamping screw.

Checking and Adjusting the Choke Cable

If the engine produces black smoke or is difficult to start, this can be because the choke cable is incorrectly adjusted (upper cable).

If doubts arise, contact the service workshop. If adjustments are necessary, they can be made as follows:

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

2.Check that the choke cable is mounted in the upper lever, see illustration. Push the choke cable’s outer casing as far to the right as possible and tighten the clamping screw.

Check and clean the cooling air intake
