Hold the switch to the right to rotate the platform coun-
terclockwise. Hold the switch to the left to rotate the
platform clockwise.
Engine/Emergency Power Switch
Hold the engine/emergency power switch down to oper-
ate aerial platform functions using the emergency power
system. Release the switch to disengage the emergency
power system.
Note
The emergency power system is for lowering the plat-
form during an emergency and is not intended for normal
machine operation.
If the engine is running, it will stop when the switch is
placed in the emergency power position.
Engine Speed Switch
The engine speed switch is used to set the engine
throttle speed to either low or high idle.
Place the switch in the low position for normal machine
operation and in the high position for engine operation
or hydraulic system warm-up.
Fuel Switch
Engines on machines with the dual fuel option can be
operated using gasoline or liquefied petroleum gas
(LPG). Dual fuel machines have a gasoline tank at the
rear of the turntable and an LPG tank behind the door
on the right side of the turntable.
The fuel switch may be used to select between gasoline
and LPG operation.
Place the switch up to operate the engine using gasoline
and down to operate on LPG.
Hydraulic System Warm-Up Switch
Some units may have an optional hydraulic fluid warm-
up system. This system may be used to warm the
hydraulic fluid when the ambient temperature is below
32°F (0°C) and boom movement is sluggish because
of cold fluid.
There is a toggle switch for the warm-up system on the
lower control panel and one on the left side of the upper
control panel.
The engine must be running and the switch used to turn
the system on, must be at the same location that the en-
gine was started. For example, if the engine was started
from the lower controls, the warm-up switch at the lower
controls must be used for the system to operate.
Machine functions are not operational while using the
hydraulic warm-up system.
Circuit Breaker Reset Buttons
The lower control panel electrical system has a circuit
breaker for the lift/swing, throttle, run and main circuits
(refer to Figure 6.5). There is a reset button for the circuit
breaker on the bottom of the lower control panel.
Figure 6.5 – Lower Controls
The upper control panel (refer to Figure 6.6) has a cir-
cuit breaker for the lift, swing, main and drive circuits.
The circuit breaker reset buttons are on the front of the
upper control panel.
Figure 6.6 – Upper Control Panel Front
The circuit breakers protect the electrical wiring and
components from electrical overload in case of a short
circuit or other fault. Push the button to reset the circuit
breaker.
Caution
A tripped circuit breaker indicates a malfunction in
the electrical system. Component damage can result
if the cause of the malfunction is not corrected. Do
not operate the aerial platform if the circuit breaker
trips repeatedly.
Upper Controls
The upper controls (refer to Figure 6.7) are located on
the control panel at the platform. Boom, platform, and
drive functions can be operated from the upper controls.
The following controls are located on the upper control
panel.
Start switch
