OUTRIGGERS
The four outriggers are deployed using the individual switches on the platform control box. Each lever
controls the movement of an outrigger leg, their relative positions being indicated by their position on
the control box. To allow the outrigger circuit to generate flow to the individual legs, the selector switch
is moved to the left position. This diverts flow to the outrigger circuit and at the same time energises
the boom/jack dump valve. If high throttle is selected, the engine will go to high revs, allowing the four
outriggers to be deployed in the best possible time. As the feet reach the end of travel, the high throttle
control can be turned 'off' allowing fine positioning of each leg and assisting in the levelling process.
The machine should be levelled using the indicator mounted on the machine base, clearly visible
between the outrigger controls and the platform edge. If necessary, each jack foot should have a
spreader plate inserted beneath it to spread the foot load and prevent sinking. The machine must be
set up level before the booms are elevated, on firm ground or with the working area adequately
consolidated.
FAILURE TO DEPLOY THE OUTRIGGERS CORRECTLY COULD RESULT
IN DEATH OR SERIOUS INJURY.
