Chapter 8 – Operation

40 TB47J – 0075239EE

Preparing for Operation

Use the following procedure to prepare the aerial platform

for operation.

1. Perform a prestart inspection as described in Chap-

ter 7.

2. Place the battery disconnect switch in the on posi-

tion.

3. Close and latch the doors.

4. Before painting or sandblasting make sure the sand-

blast protection kit and the platform control cover are

properly installed. These options, when used prop-

erly will protect the control placards and cylinder rods

from paint overspray and abrasion while sandblast-

ing.

Lower Controls

The lower controls override the upper controls. This means

that the lower controls can always be used to operate

the platform regardless of the position of the upper con-

trol emergency stop button.

Boom, turntable, and platform functions may be oper-

ated from the lower controls. The lower controls may be

used for initial set up of the aerial platform, and for testing

and inspection.

Use the following procedure to operate boom, turntable,

or platform functions using the lower controls. Refer to

Figure 8.2.

1. Pull the emergency stop button (refer to Figure 8.2)

outward. Insert the key in the control selector and

turn the switch to the lower control position.

2. Press the start button until the engine starts, then

release. The engine will not start if the control selec-

tor switch is left in the lower control position for 30

seconds or longer before starting the engine. The

control selector switch must be turned back to off

before the engine will start.

3. Let the engine warm to operating temperature.

4. Hold the ground operation switch up while operating

the control toggle switches.

5. Hold the appropriate toggle switch in the desired di-

rection.

6. Release the function toggle switch to stop movement.

7. Place the ground operation switch in the off position

when no functions are being operated.

Figure 8.2 – Lower Controls

Upper Controls

The upper controls may be used for driving the aerial plat-

form and positioning the booms and platform while on the

job.

tions using the upper controls.

1. At the lower controls, pull the emergency stop but-

ton outward. Insert the key in the control selector

and turn the switch to the upper control position.

points.

5. Turn the anti-restart master switch to on and pause

a few seconds while the alarm sounds to alert others

that the machine is about to start. Turn the switch to

start, then release it to on. The engine will not start if

the switch is left in the on position for 30 seconds or

longer before turning it to start. The switch must be

turned back to off before the engine will start.
