12. MACHINE TRAVEL - UNELEVATED Travel functions are possible only from the
platform Upper Control Station. As with all such controls, the deadman handgrip switch
must be depressed before any function can operate.
Select Drive on the upper control panel. Pushing back and forward on the joystick
moves the machine backwards and forwards respectively.
The pothole protection will begin to retract immediately. However, full demand speed
will not be realised until the bars are fully raised. This takes about 3 seconds. Check
that the motion alarm DOES sound during travel. Check that the thumb operated
switches on the top of the joystick operates the front wheel steering.
13. MACHINE TRAVEL-ELEVATED While the masts are raised, it is possible to drive and
steer the machine at a much reduced speed. Also note that while the masts are raised,
the pothole protection bars should be fully extended and should remain extended
during slow speed motion of the machine.
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.

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.

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.
