MACHINE OPERATION
The following sequence of basic procedures must be fol-
lowed to safely operate the machine.
1.
At the ground control station, set power PLAT/OFF/
GRND key switch to the PLAT position to operate
from platform control, or GRND to operate from
ground controls. Note if equipped with optional Pro-
grammable Security Lock see Section 5 for instruc-
tions then return here to continue.
2.
Check that the EMERGENCY STOP button on the
GROUND and PLATFORM control are in the RESET
position for operation. Also check that Emergency/
Manual Decent Control valve is closed (lower access
opening in rear cover).
3.
Check the LED strip on the platform controller for
current battery charge level before operating lift to
be certain charge is sufficient to complete your work
task. If the battery charger is plugged into an AC
outlet, drive functions on the machine will be locked
out.
NOTE: If LED’S are flashing a fault code on the platform
control box at machine power-up, depress the
EMERGENCY STOP button and RESET it to clear any
false fault codes. If the fault continues after RESET,
see Section-3, “Troubleshooting” of the Service and
Maintenance Manual for information on reading fault
codes.
WORK AREA MUST BE A SMOOTH, FIRM AND LEVEL SURFACE
FREE OF HOLES, LARGE CRACKS OR DEBRIS ON SURFACE. THE
WORK SURFACE MUST BE CAPABLE OF SUPPORTING THE WEIGHT
OF THE MACHINE PLUS THE PLATFORM’S MAXIMUM RATED LOAD
CAPACITY. ALWAYS CHECK THE BUBBLE LEVEL INDICATOR ON
BASE FRAME TO BE SURE MACHINE IS LEVEL BEFORE RAISING
PLATFORM.
4.
Inspect work area before operating lift.
Interlock Switch Operating Conditions
Table 4-1. shown, lists machine response to various inter-
lock switch positions.
