When the engine is running, it is possible to engage the parking brake acting on the switch placed on the
steer column
(see chapter in the manual).
When engaging the parking brake, the joystick must be in the neutral position.
To disengage the negative parking brake, a minimum pressure of about 18 bar is required. This
pressure comes from the boost pump of the main hydrostatic pump.
If the pressure goes below this value, the park brake lamp on the main instrument will switch
on.
If the park brake turns on with the engine running and without acting on the park brake switch,
stop immediately the engine and the machine and verify the brake circuit to have the correct
pressure again. Check also the boost pump of the main hydraulic pump.
Address to the authorised Service.
It is absolutely forbidden to drive the machine if the parking brake light is on when the engine
is running.
Park brake is controlled by an hydraulic valve:
1) Park brake valve
This valve is controlled by the park brake switch on the dashboard.
