Checking and adjusting the throttle control
Check that the engine responds to throttle
increases and that a good engine speed is
attained at full throttle.
Front stop screw for max speed is sealed.
Breaking the seal can invalidate the engine
warranty.
If adjustments are necessary, they can be
made as follows for the cable:
1. Move the throttle control to maximum
speed and check that the arm for the
regulator lightly supports the front stop
screw.
2. Move the throttle control to idling and
check that the arm for the regulator
supports the rear stop screw.
3. If necessary, move the cable casing in
its rear mounting.
4. Start the engine and check the idling
speed. Adjust the rear stop screw if
necessary.
5. Move the throttle control to max. speed
and check the maximum speed.
Adjusting the hydrostatic control and the neutral position
If the machine tends to run forwards or back-
wards when the engine is running and the
pedals are unaffected, the spring tension at
the pump's control arm can be altered by
turning the eccentric cam by the spring.
WARNING!
Incorrect adjustment may cause
dangerous machine handling.
The hydrostatic control is adjusted as follows:
1. Raise the machine so that the wheels
rotate freely.
2. Loosen the lock nut slightly, the eccen-
tric cam should be hard to turn.
3. Turn the eccentric using a spanner.
4. Tighten the locking nut.
5. Test drive.
6. Stop the engine and repeat from point 2
if necessary.
7. Check the status of the LED, to ensure
that the sensor is activated when the
pedals are unactuated.
