  • Page 96 Before starting the engine, make sure the system is off (by turning off the ventilation fan) so as not to overload the battery. After the system at full power for a long period of time, never turn it off suddenly Warning but let it first idle for about 20 seconds.
  • Page 97 ► ► ► ► AIR CONDITIONING SYSTEM The system is designed to ensure optimum temperature inside the cab and maximum comfort and safety for the operator. However, it is advisable to consult our specialized workshops whenever repairs or adjustments need to be performed. Do not approach the system with open flames, as any escape from the circuit may produce a lethal gas.
