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 counter-

clockwise. Hold the switch to the left to rotate the plat-

form 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 ma-

chine 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 position for normal machine

operation and in the high position for engine operation or

hydraulic system warm-up.

Ether Injection Switch – Cummins Only

Some Cummins engines may have an either injection

system instead of a block heater. Either injection should

only be used to start a cold engine when the ambient

temperature is below 0°C (32°F).

Activate the toggle switch while the start switch is in the

start position to inject a measured amount of ether into

the intake manifold.

Manifold Air Inlet Heater – Deutz Only

Some Deutz engines may have a glow plug type mani-

fold or air inlet heater. The air inlet heater should only be

used to start a cold engine when the ambient tempera-

ture is below 0°C (32°F).

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 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

engine 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 lift/swing circuit (refer to Figure 6.4). There

is a reset button for the circuit breaker on the bottom of

the lower control panel

The wiring box (refer to Figure 6.5) electrical system has

a circuit breaker for the main, run, and throttle circuits.

There is a reset button for each circuit breaker on the

front of the wiring box.

Figure 6.5 – Wiring Box

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

breaker for the main and drive circuits. The circuit breaker

reset buttons are on the front of the upper control panel.
