Checking and adjustment of the throttle
wire
Check that the engine responds to the throttle
control and that the correct engine speed is
achieved at full throttle.
If in doubt, contact the service workshop
If adjustment is necessary, adjust the lower wire as
follows:
1. Release the clamping screw that secures the wire
casing and set the throttle control to full throttle.
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 in doubt contact your service workshop.
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.
MAINTENANCE
Adjusting the differential lock
The differential lock (on the left) is adjusted as
follows:
1. Make sure the differential lock is disengaged,
with the pedal fully raised.
2. Adjust so there is zero play between the outer
cable and the adjuster screw, using the two nuts
on the adjuster screw. You should not feel any
play when you pull the outer cable.
3. Tighten the nuts carefully to avoid damaging the
adjuster screw.
