spring returned to the engine position for aerial platform
engine operation.
A
Caution
The emergency power system is for emergency low-
ering and stowing only. The length of time the pump
can be operated depends on the capacity of the bat-
tery. Do not use this system for normal operation.
• Hold the engine/emergency power switch downward
in the direction of the white arrow to activate the
emergency power system.
• Release the switch to disengage the emergency power
system.
If the engine is running, it will stop when the switch is
placed in the emergency power position.
Horn Switch
The horn switch is to the right of the emergency stop but-
ton on the upper control panel (refer to Figure 6.6).
Hold the switch upward to sound the horn.
Platform Foot Switch
The upper controls are interlocked through the platform
foot switch (refer to Figure 6.8).
Figure 6.8 – 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.
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.
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.
A
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.
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 oil warm-up switch in the off position.
