If the hydraulic system fails, the aerial platform may be
lowered using the manual emergency lowering pump.
Manual Emergency Lowering Pump
The emergency lowering pump allows the platform to be
lowered only. Only use this method if the engine will not
start and the hydraulic system has failed.
Use the following procedure to manually lower the plat-
form.
A
Danger
Pinch points exist on the elevating assembly. Death
or serious injury will result if the platform lowers onto
personnel. Stand clear while raising and lowering
the platform.
1. Open the door on the right side of the chassis to
access the manual emergency lowering pump.
2. The pump handle is mounted next to the lower con-
trols. Insert the handle into the pump (refer to Figure
10.1).

3. Pull and hold the scissor lower knob outward while
pumping to lower the platform. Stop pumping and
release the knob to stop descent of the platform.
A
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious in -
jury could result from such accidents. Fully close the
platform knob before operating the aerial platform.
4. Place the pump handle back in its holder.
