Hand and Foot Throttles
Description
The combined foot and hand throttle controls are designed
to operate in conjunction with each other. Once the engine
has been started, the hand throttle can be set to give an
engine speed suitable for the operations to be performed.
This hand setting can be overridden by the foot throttle to
give a speed in excess of that set by the hand throttle, up to
the maximum for the engine as set in the factory. However,
when the foot throttle is released, the engine speed reverts
to that set by the hand control.
Removal
Undo the connector A to expose the hand throttle cable
connection. Disconnect the cable by twisting and pulling.
The hand throttle may then be removed by undoing nut B
and lifting the unit from the instrument panel.
Lift the floor panel on which the foot throttle is mounted until
the underside of the foot throttle is exposed, then
disconnect the linkages at the white plastic clip C and the
black clip D. Remove the screws (3 off) securing the foot
throttle to the floor panel, lift off the unit and remove.
Replacement
Replacement is a reversal of the removal procedure.
Adjustment
The maximum flow and speed adjustments are sealed and
should only be adjusted by a specialist agent. Only idling
and non-stalling settings may be adjusted (see page D/1 -
2).
