18. Engine Distress Indicator (If Equipped).
The engine distress indicator lights to inform the
operator of a condition where the engine has lost oil
pressure or the engine is overheating.
19. Auxiliary Power.
The AUXILIARY POWER control switch energizes the
electrically operated hydraulic pump, when actu-
ated. The switch must be held on for duration of aux-
iliary 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 hydraulic
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. Position the POWER/EMERGENCY STOP switch
to the ON position.
c. Depress and hold footswitch.
d. Operate appropriate control switch or lever for
desired function and hold.
e. Position AUXILIARY POWER switch on and hold.
f. Release AUXILIARY POWER switch, selected
control switch or lever, and footswitch.
g. Position the POWER/EMERGENCY STOP switch
to the OFF position.
20. Axles Set Indicator (If equipped).
The green AXLES SET indicator lights to inform the
operator that the axles are set and locked (pinned)
in position.
21. Lights Switch (If equipped).
The LIGHTS switch allows the operator to turn the
installed light options on or off.
NOTE: One of the capacity indicator lights should be illumi-
nated at all times during operation. If no capacity
lights are on, a bulb could be burned out. Operation
of the machine must be halted until the lights are
working properly.
Check the capacity decal in the platform and at the
ground control station for the machines operating
capacity(s).
22. Capacity Indicator.
The capacity indicator displays to the operator the
maximum rated platform capacity and the maximum
radius for that capacity using different colored lights
and a reach diagram. The operator must not exceed
the rated capacity or the maximum radius for the
load (personnel, tools, and supplies) shown on the
indicator.
A light for each different capacity is used; blue indi-
cates operating within maximum capacity range, yel-
low indicates operating within reduced capacity
range. Models equipped with Extend-A-Reach only
have a blue and a red light. When moving the plat-
form from one capacity area to another, one light will
go out and another will come on indicating the cor-
rect capacity for that area. A steady red light indi-
cates you have exceeded the machines operating
radius. You must immediately stop and ‘’LIFT UP’’ or
‘’TELE IN’’ until the red light goes out. A blinking red
light and a buzzer sounding indicates you have
exceeded the platform load capacity (personnel,
tools, and supplies) and maximum radius. You must
immediately stop all functions and then ‘’LIFT UP’’ or
‘’TELE IN’’ until the red light goes out and the buzzer
stops. Check to make sure the load in the platform
does not exceed the rated capacity.
23. Broken Extend Chain Indicator.
The broken extend chain indicator lights in the event
of a broken extend chain in the boom.
