Step down on and hold the platform foot switch to activate
the drive and boom functions from the upper controls.

Machine/Generator Switch

The switch for the optional AC generator (refer to Figure
6.5) is located on the front of the upper control panel.
With the engine running, place the switch downward

to the generator position to provide electrical power
to the electrical outlet at the platform.
Place the switch upward to the machine position to

turn off the generator and resume machine opera-
tion.
Machine functions will not operate while the switch is in
the generator position.

Hydraulic System 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 on the lower
control panel and one on the upper control panel.

Note
Machine functions are not operational while using the
hydraulic warm-up system.
To warm-up the hydraulic fluid from the upper controls:
1. Start the engine from the upper controls.
2. Place the hydraulic fluid warm-up switch in the on
position.
The engine throttle speed will increase to warm

the hydraulic fluid.
The engine throttle speed will decrease and

return to idle once the hydraulic fluid reaches a
preset temperature.
If the warm-up switch is left on the engine speed

will continue to increase and decrease to keep
the hydraulic fluid at a preset temperature.
3. When the engine throttle speed returns to idle, place
the hydraulic fluid warm-up switch in the off 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 behind the door
on the left side of the turntable and an LPG tank on the
right side of the turntable.
The dual fuel switch to select between gasoline and LPG
operation is on the lower control panel.
Place the switch up to operate the engine using gasoline
and down to operate the engine using LPG.

Driving and Platform Work Lights

The control for the optional driving and tail lights is on the
right side of the upper control panel. Place the switch in
the on position to operate the driving lights. There is also
an individual light control on the back of each light.
There is a control for the optional platform work lights on
the back of each light (refer to Figure 6.6).
