main tap to the gas bottle should be securely closed, to prevent the engine from trying to run on a
mixture of the two fuels. If starting to run on LPG, it should be ensured that all gasoline is discharged
from the carburettor bowl before changing to LPG, since the engine will not run satisfactorily if any
gasoline is in the carburettor bowl.

FUNCTION SELECTOR: Four Wheel Drive:
The hand operated duty selector is situated adjacent to
the drive/steer joystick and the electrical solenoid outrigger controls. Grasping the handle automatically
routes the hydraulic flow through to the outrigger and drive circuit and at the same time operates the
micro switch to run the appropriate power option chosen. This then permits the use of either jack
deployment or machine drive. Releasing the spring loaded handle returns it to the boom position. As
soon as the boom raises, the electric micro switch is disabled denying the use of the outrigger and
drive functions whilst elevated. As before, the boom circuit needs all four outriggers to be in contact
with the ground before it will operate.

SPEED CONTROL:
A two position selector allows high throttle for the engine to be selected, or twin
power pack operation for fast speed duty. This will operate when the booms are lowered, to allow fast
set-up of the outriggers, and fast drive speed.
