18. Choke (If Equipped).
A push-button switch supplies power to the choke
solenoid for cold weather starting.
19. Glow Plug (If Equipped).
This push-button switch when depressed supplies
power to the diesel engine glow plugs for cold
weather start. See diesel engine operator manual
for instructions.
20. Engine Distress Light (Red).
This indicator lights to notify the operator that the
engine has no oil pressure, is overheating (water or
oil), or is not producing voltage. The light will also
come on if the engine has stalled.
21. Auxiliary Power.
The AUXILIARY POWER control switch energizes
the electrically operated hydraulic pump, when
actuated. The switch must be held on for duration of
auxiliary pump use.
The auxiliary pump functions to provide sufficient oil
flow to operate the basic machine system should
the main pump or engine fail. The auxiliary pump
will operator boom lift, telescope and swing.
It should be noted that the functions will operate at
a slower than normal rate because of lower hydrau-
lic flow.
WHEN OPERATING ON AUXILIARY POWER, DO NOT OPERATE
MORE THAN ONE FUNCTION AT THE SAME TIME. SIMULTA-
NEOUS OPERATION CAN OVERLOAD THE AUXILIARY PUMP
MOTOR.
NOTE: The main function of the auxiliary power is to lower
the platform in the event of primary power failure.
Determine the reason for primary power failure and
have the problem corrected by a qualified service
technician.
NOTE: Auxiliary power is primarily intended for platform low-
ering in the event of primary power failure. However,
auxiliary power may be used for platform positioning
when operating in close quarters in the following
sequence:
a. Position PLATFORM/GROUND switch to PLAT-
FORM.
b. Pull the POWER/EMERGENCY STOP switch out
to the on position.
c. Depress and hold footswitch.
d. Operate appropriate control switch or lever for

e. Position AUXILIARY POWER switch on and hold.
f. Release AUXILIARY POWER switch, selected
control switch or lever, and footswitch.
g. Push the POWER/EMERGENCY STOP switch to
the off position.

The LIGHTS switch allows the operator to turn the
installed light options on or off.
24. Capacity Indicator (If equipped).
The CAPACITY INDICATOR GAUGE is mounted on
the left side of the platform console. The indicator
scale is visible through a lens and indicates the
maximum platform load allowable at any given
boom angle and extension based on the color
stripe visible at the point where the fly boom enters
the mid boom.
