EMERGENCY SITUATIONS
In any emergency situation, the immediate action is to push the red “Emergency Stop”
button. This will instantly cut of all electrical power to the controls. The button must be
twisted in a clockwise direction in order to recommence control. However, the switch should
be reset only when it is safe to do so.
If the Audible warning alarm sounds, normal control functions will cease to operate. This
will be due to the following problem;
• The Tilt Sensor has been activated
EMERGENCY LOWERING (BY HAND)
C A U T I O N
During manual emergency lowering, extreme care must be taken to ensure
that the person carrying out the task is not struck by the jib or platform
structure.
Should the machine become inoperable when elevated request a person on the ground to
lower the platform using the emergency lowering valves. Lower the mast structure before
lowering the jib/platform structure.
NOTE: Lower the masts fully before lowering the jib structure.
Figure 8: Emergency Lowering - Mast Valve
Locate the red lever behind the mast
cover inspection door on the left hand
side of the machine. By pushing the
lever up, the mast will descend fully
under gravity. Releasing the spring-
loaded lever will cease this operation
immediately if required.
Figure 9: Emergency Lowering - Jib Valve
The Jib may be manually lowered by
operating the manual release valve
located between the Jib Structure.
MANUAL ROTATION
1. Lower the masts and jib fully before manually slewing the assembly. Press the Emergency
Stop Button to prevent inadvertent powered motion.
2. Locate the opening behind the front right drive wheel. Apply a 23 mm socket wrench with
extension bar to the shaft and turn to rotate the elevating assembly. (Turning the front
wheel fully to one side will facilitate this operation).
