ARSC (AUTOMATIC RETARDER SPEED CONTROL)
METHOD OF DECREASING SET TRAVEL SPEED
If it is desired to decrease the set speed, operate the retarder control lever to reduce speed, and when the desired
set travel speed is reached, press the set switch on the ARSC set lever. The set travel speed will be changed to the
new speed.
REMARK
After using the retarder control lever to reduce the speed, return it to its original position.
TRAVELING AGAIN AT SET TRAVEL SPEED
If the machine repeatedly travels on the same slope, once the travel speed has been set, it is possible to operate
the ARSC without carrying out the setting operation each time.
Before entering a downhill slope, if the travel speed has been adjusted to a speed lower than the set speed displayed
on the travel speed display, the READY lamp (green) lights and the ARSC is actuated when the accelerator pedal
is released.
REMARK
When traveling at a speed greater than the set speed displayed on the travel speed display, the ARSC is not
actuated even when the accelerator pedal is released. When this happens, the READY lamp (green) also does not
light up. Always adjust the travel speed to a speed lower than the set speed displayed on the travel speed display,
and check that the READY lamp lights up.
METHOD OF CANCELING SET TRAVEL SPEED
Method 1: If the cancel operation is carried out for more than 1 second, the control is stopped. When this happens,
the set speed display shows 0.
Method 2: If the system switch is turned OFF, the control is canceled. When this happens, the set speed display
goes out.
REMARK
For Method 1, cancel operation must be continued for at least 1 second (different from other switches) to cancel the
control. This is to prevent any problem of the control being canceled if the switch is touched by mistake.
RELATIONSHIP WITH EXHAUST BRAKE
If the exhaust brake switch is at ON position (light is on), the exhaust brake is actuated in the normal way when the
accelerator pedal is released if the torque converter lock-up is ON (Lock-up pilot lamp lights up). When the machine
attempts to travel at a speed greater than the set speed, the ARSC is also actuated if the speed is set in the way
stated above.
If the exhaust brake switch is at OFF position (light is off), the exhaust brake is not actuated when the ARSC is being
operated. If the foot brake or retarder control lever are operated, the exhaust brake is actuated in the same way as
normal.
If the downhill slope is not steep and the engine brake and exhaust brake have ample effect, the machine will not
accelerate to the set travel speed, so the ARSC may not be actuated.
RECOMMENDED SET TRAVEL SPEED
Set the travel speed so that the engine speed is at least 1,800 rpm, and travel so that the retarder oil temperature
gauge is in the green range.
OVERHEAT WARNING
If there is danger that the retarder oil may overheat, the ARSC caution lamp lights up and the set travel speed is
automatically reduced 1 km/h (0.6 MPH) every 3 seconds. The lower value for the set travel speed when the speed
is automatically reduced is 10 km/h (6.2 MPH).
