2.2 Component Identification

The following descriptions are for identification,
explanation and locating purposes only.

2.2-1 Main Power Disconnect Switch

This switch is located at the side of the hydraulic/
electrical compartment.
Figure 2-1. Main Power Disconnect Switch
1. Main Power Disconnect Switch - This switch,
when in " " off position, disconnects power
to all circuits. Switch must be in " " on position
to operate any circuit. Turn switch off when
transporting aerial platform.

2.2-2 Motion Alarm

The alarm produces an audible sound when any control
function is selected. On aerial platforms with certain
options, a flashing amber light will accompany this
alarm.

2.2-3 Tilt Alarm

The aerial platform is equipped with a device which
senses when the aerial platform is out of level in any
direction. When activated, it disables drive and lift
functions of the aerial platform and an alarm produces
an audible sound accompanied by the amber light. If
the alarm sounds, lower the platform completely, then
reposition aerial platform so that it is level before raising
the platform.
NOTE
If the tilt alarm sounds and the platform does
not, or only partially raises, immediately
lower the platform completely and ensure
that the aerial platform is on a firm level
surface.

contained in this operating manual and on the aerial platform.
Section 2 - Familiarization
2.2-4 Load Sensing System
This system is a safety device that prevents any normal
movement of the aerial platform from a stationary
working condition after the rated load is reached and
exceeded. Refer to Table 4.4
capacities.
• When 90% of the rated load is reached:
The red power indicator light on the platform
control console flashes.
• When the rated load is reached:
An audible alarm sounds for approximately
2 seconds, 5 times per minute.
• When the rated load is exceeded:
The flashing light and audible alarm continue and
all electrically controlled aerial platform movement
functions stop. To resume normal operation,
remove the overload from the platform.
• If the aerial platform during the operation comes
in contact with an overhead obstruction:
The platform could become overloaded and all
functions would stop. Release of the platform
from this situation can only be effected by use
of the emergency lowering system. Refer to
Section 2.6.
After reaching full extension and upon
lowering, the aerial platform could stop
and take an overload reading. Return the
proportional controller to the neutral center
position, and release the enable trigger
switch. If the aerial platform is overloaded,
the flashing light and audible alarm
continue and all electrically controlled
aerial platform movement functions stop.
To resume normal operation, remove the
overload from the platform.
