22. Low Fuel Indicator. (Yellow)
When illuminated (Yellow), the fuel tank is 1/8 full or
less. When the light first turns on, there are approxi-
mately four usable gallons of fuel remaining.
23. Capacity Indicator (CSA & Australian).
When illuminated (Red), the light indicates the maxi-
mum platform capacity for the current position of the
platform. 455 kilograms capacity is permitted at
restricted platform positions (shorter boom lengths
and higher boom angles), and 230 kilograms is the
maximum capacity in all other positions.
24. Auxiliary Power.
A toggle-type AUXILIARY POWER control switch
energizes the electrically operated hydraulic pump,
when actuated. (Switch must be held ON for dura-
tion of auxiliary pump use.)
The auxiliary pump functions to provide sufficient oil
flow to operate the basic machine functions should
the main pump or engine fail. The auxiliary pump will
operate tower boom lift, tower telescope, main
boom lift, main telescope and swing.
It should be noted that the functions will operate at a
slower than normal rate because of the lower gpm
delivered.
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 auxiliary power is to lower the
platform in the event of primary power failure. Deter-
mine the reason for primary power failure and have
the problem corrected by a certified JLG service
technician.
NOTE: Auxiliary power is primarily intended for platform
lowering in the event of primary power failure. How-
ever, auxiliary power may be used for platform posi-
tioning when operating in close quarters in the
following sequence:
a. Position PLATFORM/GROUND switch to PLAT-
FORM.
b. Position POWER/EMERGENCY STOP switch to
ON.
c. Depress and hold footswitch.
d. Operate appropriate control switch or lever for
desired function and hold.
e. Position AUXILIARY POWER switch to ON and
hold.
f. Release AUXILIARY POWER switch, selected
control switch or lever, and footswitch.
g. Position POWER/EMERGENCY STOP switch to
OFF.
3.5 PLACARDS AND DECALS
Read and understand all placards and decals. Do not
operate any machine on which DANGER, WARNING,
CAUTION OR INSTRUCTION PLACARDS OR DECALS
ARE MISSING OR ILLEGIBLE. Replace placards and
decals if damaged, missing or illegible.
Decals are made of Lexan Pressure Sensitive Adhesive
with a protective film on the front. Remove the damaged
decal and thoroughly clean surface before installing a new
decal. Simply peel off, press on to surface.
NOTE: Placards and Decals can be ordered by using part
numbers located by each placard or decal. (Figure 3-
8.)
