Circuit Breaker Reset Buttons

The lower control panel electrical system has a circuit

breaker for the lift/swing, throttle, run and main circuits

(refer to Figure 6.5). There is a reset button for the circuit

breaker on the bottom of the lower control panel.

Figure 6.5 – Lower Controls

The upper control panel (refer to Figure 6.6) has a cir-

cuit breaker for the lift, swing, main and drive circuits.

The circuit breaker reset buttons are on the front of the

upper control panel.

Figure 6.6 – Upper Control Panel Front

The circuit breakers protect the electrical wiring and

components from electrical overload in case of a short

circuit or other fault.

Caution

A tripped circuit breaker indicates a malfunction in

the electrical system. Component damage can result

if the cause of the malfunction is not corrected. Do

not operate the aerial platform if the circuit breaker

trips repeatedly.

Push the button to reset the circuit breaker.

Upper Controls

The upper controls (refer to Figure 6.7) are located on

the control panel at the platform. Boom, platform and

drive functions can be operated from the upper controls.

The following controls are located on the upper control

panel.

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 coun-

terclockwise. Hold the switch to the left 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 plat-

form 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.

Throttle Switch

The throttle switch (refer to Figure 6.4) is used to set the

engine throttle speed in either low or high idle.

Place the switch in the low position before starting the

engine and in the high position for machine operation

and for engine and/or hydraulic system warm-up.

The engine has a two speed throttle operation from the

lower controls. When the throttle switch is in the low posi-

tion the engine is at idle. Placing the switch in the high

position increases the engine speed to mid-range.

Placing the ground controls switch in the on position also

increases the engine speed to mid-range.

Hydraulic System Warm-Up Switch

Some units may have an optional hydraulic fluid warm-

up system. This system may be used to warm the

hydraulic fluid when the ambient temperature is below

0°C (32°F) 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.
