Flashing Light
The machine may be equipped with an optional flashing
light mounted to the top of the counterweight.
To inspect the flashing light:
1. Turn the battery disconnect, pull the emergency stop
button outward at the lower controls, and turn the start
switch on.
2. Visually check to see that the light is flashing ap-
proximately one flash per second.
Note
There is not an off switch for the flashing light. The light
cannot be turned off while the start switch is in the on
position.
Structures
Visually inspect all weldments and related components.
It is important to inspect the fasteners that connect the
components.
Weldments
To inspect the weldments:
1. Visually inspect all weldments for abnormal wear,
abrasion, or deformation that could cause interfer-
ence between moving parts.
2. Inspect the welds on the structural components.
Pay particular attention to boom welds. The area to
be inspected should be clean and free of dirt and
grease.
3. Look for visible cracks in the welds and at the weld
to parent material joints. A bright light may be used
to provide adequate visibility of the inspection area.
Boom Slide Pads
The main boom has slide pads (refer to Figure 7.11)
between the main and tip boom sections.

Emergency Power
To test the emergency power system from the lower
controls:
1. Place the battery disconnect switch, the emergency
stop switch, and the start switch in the on position.
2. Hold the engine/emergency power switch down
and the ground operation switch upward to operate
the aerial platform from the lower controls using the
emergency power system.
Level Sensor
Use the following procedure to test the level sensor:
1. Position the aerial platform on a smooth, flat, level
surface.
2. Remove all persons and materials from the plat-
form.
3. Start the engine and raise the main boom above
horizontal, approximately 15 to 20 degrees.
4. Remove the engine cover. The level sensor is in the
right side of the engine compartment (refer to Figure
7.10).

5. Pull the level sensor to the side as far as possible to
activate the tilt alarm.
A
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. Do not alter,
disable, or override any safety device.
6. If the alarm does not sound, remove the machine
from service until the problem is corrected.
7. Lower the main boom.
