The aerial platform may be lowered using the emergency lowering slew, hand pump or switch.
Use the following procedure to operate the emergency lowering system.
1. Immediately push the emergency stop button inward to disable the control system in the event of
an emergency.
2. Locate the emergency lowering control.
3. Make sure there is nothing in the way to obstruct the platform when it lowers.
4. Stand clear of the boom structure.
EMERGENCY SLEW
A 17 mm socket together with a lever or spanner may be used to move the platform if there is a
malfunction in the hydraulic or electrical system.
In the event of a failure, the machine can be manually slewed by moving the slew platform clock-
wise or anticlockwise by inserting the slew lever and rotating the gearbox by moving upwards and
downwards.
