the platform controller to perform this test.
1. Position the machine on a level, firm surface. Start
the machine, and the green indicator light on the
level sensor should illuminate.
2. With the machine in stowed position, place 2
wooden blocks near the two front or rear wheels,
then drive the machine upon the wooden blocks.
The wooden block dimension (L×W×H) is
100×50×150mm (4in×2in×5.9in).
3. Switch from drive to platform lift function, and raise
the platform until the lower limit switch disengages,
the red indicator light on the level sensor will
illuminate with the alarm sounding, and further
lifting and driving is restricted.
4. Lower the platform to the stowed position, the alarm
will stop sounding, and the machine function limit is
cancelled.
5. Drive the machine off and remove the wooden
blocks.
6. With the machine in stowed position (outrigger
retracted), place 2 wooden blocks near the two
wheels on the left or right side, then drive the
