When performing the steer and drive function test, stand in the platform facing the steer end of
the machine.
Press the drive function select button. The indicator light should turn on.
Press and hold the function enable switch on the proportional control handle. Depress the thumb
rocker switch on top of the proportional control handle in the direction identified by the blue
triangle on the control panel.
Result:
The steer wheels should turn in the direction that the blue triangle points on the
control panel.
Press and hold the function enable switch on the proportional control handle. Depress the thumb
rocker switch in the direction identified by the yellow triangle on the control panel.
Result:
The steer wheels should turn in the direction that the yellow triangle points on the
control panel.
Test Drive and Braking
Press the drive function select button. The indicator light should turn on.
Press and hold the function enable switch on the proportional control handle.
Slowly move the proportional control handle in the direction indicated by the blue arrow on the
control panel until the machine begins to move, then return the proportional control handle to the
center position.
Result:
The machine should move in the direction that the blue arrow points on the control
panel, then come to a firm stop.
Press and hold the function enable switch on the proportional control handle.
Slowly move the proportional control handle in the direction indicated by the yellow arrow on the
control panel until the machine begins to move, then return the proportional handle to the center
position.
Result:
The machine should move in the direction that the yellow arrow points on the control
panel, then come to a firm stop.
Note:
The brakes must be able to hold the machine on any slope it is able to climb.
Test Limited Drive Speed
Press the lift function select button. The indicator light should turn on. Raise the platform
approximately 10 feet (3 m) from the ground.
Press the drive function select button. The indicator light should turn on.
Press and hold the function enable switch on the proportional control handle slowly move the
proportional control handle to the full drive position.
Result:
The maximum achievable drive speed with the platform raised should not exceed the
creep speed of 0.5 mph (0.8 km/h).
Result:
If the drive speed with the platform raised exceeds the creep speed, immediately tag
and remove the machine from service.
Test the Tilt Sensor Operation
Note:
Perform these tests from the ground with the platform controller. Do not stand in the platform.
Take extra care when operating any drive function from the ground using the platform controller.
