5. Auxiliary Power
Energizes the electrically operated pump, when actuated.
(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 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 deliv-
ered.
WHEN OPERATING ON AUXILIARY POWER, DO NOT OPERATE MORE THAN ONE FUNC-
TION AT THE SAME TIME. SIMULTANEOUS OPERATION CAN OVERLOAD THE AUXIL-
IARY PUMP MOTOR.
NOTE: The main function of 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 certified JLG service technician.
6. Fuel Select (Dual Fuel Engine Only) (If Equipped)
Gasoline or liquid propane fuel may be selected by moving
the switch to the appropriate position. It is unnecessary to
purge the fuel system before switching fuels, so there is no
waiting period when switching fuels while the engine is
running.
7. Lights (If Equipped)
Operates control console panel lights and head lights if the
machine is so equipped. The ignition switch does not have
to be on to operate the lights, so care must be taken to
avoid draining the battery if left unattended. The master
switch and / or the ignition switch at the ground control
will turn off power to all lights.
