Platform Foot
Switch
Override Switch
When the Snorkel Guard or the platform overload system
is activated, the override switch (refer to Figure 6.5) is
used to override the system to operate riser up/down,
main boom up/down/retract, jib boom up/down, or turn-
table rotation and drive functions. The switch is spring
returned to the normal operation position.
• Hold the switch upward to override the Snorkel Guard
or the platform overload system.
• Release the switch to the downward position to re-
sume normal machine operation.
Tilt Alarm
If the aerial platform chassis is out of level more than the
machine specified slope sensor alarm setting when the
main boom is raised or extended, an alarm will sound and
the tilt warning light on the lower control panels (refer to
Figure 6.5) will illuminate.
Platform Foot Switch
The upper controls are interlocked through the platform
foot switch (refer to Figure 6.7).
Figure 6.7 – Platform
Step down on and hold the platform foot switch to activate
the drive and boom functions from the upper controls.
AC Generator Switch
The switch for the optional AC generator is located on
the front of the upper control panel (refer to Figure 6.8).
Figure 6.8 – Upper Control Panel Front
With the engine running, place the switch in the generator
position to provide electrical power to the electrical outlet
at the platform. Return the switch to the off position to turn
off the generator and resume machine operation.
Machine functions will not operate while the switch is in
the generator position.
Dual Fuel
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 inside the left
side of the chassis and an LPG tank mounted on the
outside of the chassis on the left side.
There is a fuel switch to select between gasoline and LPG
operation on both the lower and upper control panels
(refer to Figure 6.2 and 6.8).
Place the switch in the proper position depending on the
type of fuel that is required.
Hydraulic Oil Warm-Up Switch
The optional hydraulic fluid warm-up switch is 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.
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of 10°F
(-12°C) or below.
The toggle switches for the warm-up system are on the
lower control panel and on the front of the upper control
panel (refer to Figure 6.2 and 6.8).
