20. Soft Touch Indicator. (If Equipped)
When illuminated (Yellow) the Soft Touch bumper is
against an object. All controls are cut out until the
override button is pushed, at which time controls are
active in the Creep mode.
21. AC Generator. (Green)
When illuminated (Green), the light indicates the
generator is in operation.
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. Auxiliary Power.
A toggle-type Auxiliary Power control switch ener-
gizes 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. Operate as follows:
a. Position Platform/Ground switch to Platform.
b. Position 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 to the on posi-
tion and hold.
f. Release Auxiliary Power switch, selected control
switch or lever, and footswitch.
g. Position Power/Emergency Stop switch to the off
position.
