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

If doubts arise, contact your service representative.

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 your service representative.

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.

Adjusting the differential lock, PF 21

The differential lock (on the left side) is adjusted in the following manner:

1.Check that the differential lock is disengaged; the pedal should be all the way up.

2.Adjust the zero play between the cable casing and the adjustment screw with the two nuts on the adjustment screw. You should feel no play when you pull the casing.

3.Tighten the nuts moderately to avoid damaging the threads.
