Section 8 - Emergency operation
Operating safely
Should the occupant of the platform suffer injury while aloft, disabling that person from
operating the platform controls, the platform may be lowered by means of the overriding
lower controls.
Danger
Before attempting to lower the platform with the lower control, for the protection of the
ground personnel, it must first be determined that the vehicle is not energized. Death
or serious injury can result from contact with equipment that has become electrically
energized.
Upon determining that it is safe to touch the vehicle, the lower controls may be used for
booms' movement.

From the pedestal controls, selecting and holding the "Override" position with the
toggle switch at the pedestal door, permits operation of the aerial device from the
lower hydraulic controls.
Emergency lowering DC pump
If a situation arises that the machine cannot be operated due to a loss of hydraulic
power, such as engine or pump failure, the emergency lowering DC pump can be used
to lower the main boom.
The 12-volt DC battery operated pump is designed for use in case the vehicle engine or
power system fails. The emergency lowering DC pump may be operated from the platform
or the pedestal controls. The pump is located near the reservoir and power is supplied to
the pump from the vehicle battery. The capacity of this pump is dependent on the capacity
of the battery.
The emergency lowering DC pump system has been designed to allow for lowering the
booms to the ground for operator rescue, but may not allow for complete storage of the
booms.
Attention
The DC pump is intended for emergency lowering use only. Do not run for over three
(3) minutes continuously. Damage to the pump or motor can result.
