21. Chassis Out of Level (Tilt Alarm) Warning Light (Red)
A warning light on the control console that lights when
the chassis is on a severe slope.
IF TILT ALARM IS ON WHEN BOOM IS RAISED OR EXTENDED, RETRACT
BOOM AND LOWER PLATFORM TO NEAR GROUND LEVEL, THEN REPO-
SITION MACHINE SO THAT IT IS LEVEL BEFORE EXTENDING OR RAIS-
ING BOOM.
TOGGLE SWITCHES OR CONTROL LEVERS CONTROLLING PLATFORM
MOVEMENT AUTOMATICALLY RETURN TO THE CENTER OFF POSITION
WHEN RELEASED.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY TOG-
GLE SWITCHES OR CONTROLLERS CONTROLLING PLATFORM MOVE-
MENT DO NOT RETURN TO THE CENTER OFF POSITION WHEN
RELEASED.
22. Platform Rotate Switch.
The PLATFORM ROTATE control switch allows the oper-
ator to rotate the basket to the left or right when posi-
tioned to the desired direction.
23. Auxiliary Power.
The AUXILIARY POWER control switch energizes the
electrically-operated hydraulic 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 system should the main
pump or engine fail. The auxiliary pump will operate
tower boom lift, 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 (lpm)
delivered.
WHEN OPERATING ON AUXILIARY POWER, DO NOT OPERATE MORE
THAN ONE FUNCTION AT THE SAME TIME. SIMULTANEOUS OPERATION
CAN OVERLOAD THE AUXILIARY PUMP MOTOR.
NOTE: The main function of the auxiliary power control 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 qualified service technician.
