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.

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.

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
