14. FINAL PREPARATION Configure the masts and jib to the stowed position. Replace all
machine covers and secure.
NOTE: The machine is now ready for Operation or Transportation.
2.4 OPERATION OF THE PLATFORM CONTROLS
The primary (Upper) control box is permanently fitted to the front of the platform. It features
a multi-use joystick which provides proportional control for all the machines functions.
That includes, raising or lowering the mast, raising or lowering the jib, rotating the mast
assembly, and also to drive and steer the machine.
A safety Interlock Switch or ‘deadman button’ is incorporated into the Joystick. It must be
activated at all times in order to operate any function. This feature allows for one-handed
operation.
The secondary (Lower) control box is fitted to the mast cover at arm level. It features an
enable button and selector buttons to provide pre-programmed speeds for all functions
except drive and steering. This control station is used primarily for service-type operations
including pre-operation inspection. It should never be used to position a manned or un-
maned platform.
NOTE: It may be used in the event of emergency to lower the manned platform.

The issue of reduced speed while elevated and deployment of
the pothole protection bars is crucial to the safe operation of this
machine.
The machine may not be released or operated unless these functions
operate properly.

required, the overload warning lamp on the platform control box will flash for 2 seconds and
the buzzer will sound twice confirming that the overload sensor has booted up.
CONTROLS AND INDICATORS
The pre-operation safety checks should be carried out prior to operation. These checks are
detailed in the previous section. Operators who follow these guidelines will become familiar
with the controls and indicators on the machine.
This section summarises the controls and indicators in tabular form and provides more
detailed information.
