Operating principle

1 - Description

Hydraulic energy for machine movement is provided by a pump unit.
The controls and the starting of the thermal engine are powered by battery.
To protect the staff and the machine, safety systems forbid the use of the machine beyond its
capacities.
These security systems immobilize the machine and neutralize the movements.
Poor knowledge of the characteristics and operation of the machine can lead the operator to think that a
normal safety operation is a malfunction.

2 - Safety devices

2.1 - ACTIVATION OF CONTROLS

The controls must be validated by a 'Dead man' system to activate the different movements.
The 'Dead man' system depends on the machine configuration :
• Joystick handle.
• Pedal.
• Validation button.

2.2 - DRIVING SPEED (MINIMUM)

All driving speeds are authorized when the machine is stowed ( machine in
lowered position).
The only speed allowed when not in stowed position is microspeed.
