3.3 OPERATING CHECKS
Machine operation: refer to Section 4 – Operation.
3.3.1 CONTROL STATIONS
• Ground control station
1- On power up, check that the lights come on (self-test).
2- Start the combustion engine and activate all the controls to check that they are working.
Check that the movement stops when the control is released. Check that the movement
stops when the enable button is released.
3- Check that the emergency stop switch cuts the movements and the diesel engine (the
diesel engine stops after around 2 seconds).
4- With the diesel engine stopped, check that the auxiliary backup group is working.
• Platform control station
1- On power up, check that the lights come on (self-test).
2- Start the diesel engine and activate all the controls to check that they are working. Check
that the movement stops when the control is released. Check that the movement stops
when the enable pedal is released.
3- Check the machine switches to slow speed when the work platform is raised.
4- Check the machine switches to slow speed when the telescope is extended.
5- Check that the emergency stop switch cuts the movements and the diesel engine (the
diesel engine stops after around 2 seconds).
6- With the diesel engine stopped, check that the auxiliary backup group is working.
3.3.2 LOCKING THE OSCILLATING AXLE
1- Place a wedge with an access slope of
around 15cm in height in front of the front
right-hand side wheel.
2- Ensure the machine is fully lowered.
3- Slowly drive the machine forward until the
wheel is on the wedge.
4- Turn the structure beyond the rear axle.
5- Slowly drive down from the wedge.
6- Check the axle stays locked: the right-hand side wheel does no longer contact the ground.
7- Return the structure in line with the chassis.
8- Drive the machine in slow speed: the axle should unlock, and the right-hand side wheel
should contact the ground.
9- Repeat the previous procedure placing the wedge under the front left hand side wheel.
