7.7 Procedure in the event of malfunctions
7.7.1 Switching on emergency operation in coolant circuit
The speed of the fan wheel for the engine is automatically controlled. You
can switch on the emergency mode if this automatic system fails. The fan
wheel then runs at maximum speed when the engine is switched on.
• Switch off the engine and secure against unauthorised use – lock the
hand-held control in the driver's cab and the doors.
• Disconnect the plug connection (1).
• Fasten the plug connection (1) so that it
will not be damaged when the engine is
running.
Emergency operation is switched on and the
fan wheel runs at maximum speed when the
engine is switched on.
• Have the cooling system immediately
checked and repaired by a specialist
workshop.
G
Risk of accidents by turning fan wheel!
Always switch off the engine and secure it against unauthorised start
before switching on emergency operation.
This prevents the fan wheel from turning suddenly and injuring you.
G
Risk of burns when the engine is hot!
During operation, the engine and the add-on parts heat up greatly.
Wear appropriate protective gloves and be careful not to touch hot parts.
