Hold the switch up to tilt the platform floor upward or
away from the ground. Hold the switch down to tilt the
platform floor downward or toward the ground.
Platform Rotate Switch
The platform rotator switch is used to rotate the platform
relative to the end of the tip boom. The switch is spring
returned to the center off position.
Hold the switch to the right to rotate the platform counter-
clockwise. Hold the switch to the left to rotate the plat-
form 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 platform
during an emergency and is not intended for normal ma-
chine 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.
Ether Injection Switch – Cummins Only
Some Cummins engines may have an either injection
system instead of a block heater. Either injection should
only be used to start a cold engine when the ambient
temperature is below 32°F (0°C).
Activate the toggle switch while the start switch is in the
start position to inject a measured amount of ether into
the intake manifold.
Manifold Air Inlet Heater – Deutz Only
Some Deutz engines may have a glow plug type mani-
fold or air inlet heater. The air inlet heater should only be
used to start a cold engine when the ambient tempera-
ture is below 32°F (0°C).
Hold the toggle switch up in the on position for about 60
seconds before trying to start the engine.
Hydraulic System Warm-up Switch
Some engines may have a hydraulic fluid warm-up sys-
tem. 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
engine 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 circuit (refer to Figure 6.4). There
is a reset button for the circuit breaker on the bottom of
the lower control panel
The wiring box (refer to Figure 6.5) electrical system has
a circuit breaker for the main, run, and throttle circuits.
There is a reset button for each circuit breaker on the
front of the wiring box.
