ARSC (AUTOMATIC RETARDER SPEED CONTROL)
ARSC (AUTOMATIC RETARDER SPEED CONTROL)
When traveling downhill, if the switch is pressed at the speed that is to be maintained, the retarder is automatically
actuated to prevent the travel speed from exceeding the set speed, so this makes retarder operations easy.
WARNING
The ARSC system is actuated when the system switch is ON. Before traveling downhill, check that the system switch is ON.
If the speed is set to a speed that exceeds the maximum permissible speed obtained from the brake performance graph, there
is danger that there will be overheating and that the retarder brake may be damaged. Always set the speed so that it does not
exceed the maximum permissible speed.
When the ARSC is actuated on slippery roads, the tires may lock. If this happens, cancel the ARSC.
If any abnormality occurs in the system and braking cannot be carried out properly, the alarm sounds and the system is turned
OFF to cancel the ARSC. If necessary, control the machine with the retarder control lever and foot brake to stop the machine
in a safe place, then turn the system switch OFF.
