. OPERATION OPERATION OPERATION OPERATION 5. When traveling downhill, if the machine starts to exceed the set travel speed, the retarder is actuated automatically. While it is being actuated, retarder pilot lamp (5) lights up. METHOD OF SPEED SETTING CAUTION METHOD OF CARRYING OUT FINE ADJUSTMENT OF SET TRAVEL SPEED If you want to raise the set speed by 1 km/h (tap up), push the auto retarder (ARSC) set lever up once. If you want to lower the set speed by 1 km/h (tap down), pull the auto retarder (ARSC) set lever down once. 3 - 107 REMARK on the ARSC set speed indicator on the machine.
The set travel speed is saved to memory and displayed If the accelerator pedal is depressed while the ARSC is being actuated, the actuation of the ARSC is canceled and the machine accelerates. If the brake pedal or retarder control lever is actuated w hile the ARSC is being actuated, it is possible to reduce speed or stop the machine in the same way as for the n ormal brake operation. ting gear or to the point where the grade of the slope ansmission may shift up or down. nt depending on the grade of the slope. avel speed may be slightly different.
When the set travel speed is close to the point for shif changes, even when the ARSC is being actuated, the tr The time when the set travel speed converges is differe The speed displayed on the speedometer and the set tr Set the travel speed so that it does not exceed the maximum permis sible travel speed obtained from the brake performance graph. If the travel speed is set higher than the maximum permissible tra vel speed, the retarder brake may overheat and be damaged. If the actual machine speed during the setting operation is less than 10 km/h (6.2 MPH), the speed is set to 10 km/h (6.2 MPH). If it is higher than 55 km/h (34.2 MPH) set to the actual travel speed.
, it is set to 55 km/h (34.2 MPH). In all other cases, it is The travel speeds that can be set depend on the select ion of the gear shift lever as follows. When the gear shift lever is at the D, 6, 5, 4, 3, 2, or L po to 34.2 MPH). It is impossible to set the speed when the gear shift lev sitions, the range for the set speed is 10 to 55 km/h (6.2 er is at the N or R positions. REMARK the set travel speed. the cancel operation is given priority. the tap up operation is given priority. me, the tap doen operation is given priority. ne adjustment of the set travel speed.
Release the auto retarder (ARSC) set lever after changing If the set switch and cancel are operated at the same time, If the set switch and tap up are operated at the same time, If the set switch and tap down are operated at the same ti The tap up and tap down operations are used for making fi It is possible to adjust the set travel speed up to ± 5 km/h (3 .1 MPH) when travelimg in ARSC (when the accelerator pedal released). When the accelerator pedal is being depr essed, it is possible to operate freely in a range from 10 to 55 km/h (from 6.2 to 34.2 MPH).
