Jib Articulation Switch
The jib switch is used to raise or lower the jib. The switch
is spring returned to the center off position.
Hold the switch up to raise the jib. Hold the switch down
to lower the jib.
Platform Level Switch
The platform level switch is used to level the platform floor
with respect to the ground. The switch is spring returned
to the center off position.
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 Rotation Switch
The platform rotation 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 up to rotate the platform counterclockwise.
Hold the switch down 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 platform
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 (turtle) position for normal
machine operation and in the high (rabbit) 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 behind the door
on the left side 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 to the left to operate the engine using
gasoline and to the right to operate on LPG.
Manifold Air Inlet Heater – Deutz Only
Some Deutz engines may have a glow plug type manifold
or air inlet heater. The air inlet heater should only be used
to start a cold engine when the ambient temperature 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 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 throttle, run, and main circuits (refer to
Figure 6.2). There is a reset button for each circuit breaker
on the bottom of the lower control panel
The upper control panel (refer to Figure 6.3) has a cir-
cuit breaker for the main and drive circuits. The circuit
breaker reset buttons are on the front of the upper control
panel.
