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.

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.
