When doing this, remove all the mud that is stuck to the dump body. 2. Move the gear shift lever to the N position and keep CAL/CLR switch (1) pressed for at least 2 seconds. (The letters CAL flash.) 3. Drive the machine at a speed of 10 km/h (6.2 MPH). 4.

When the travel speed reaches 10km/h (6.2 MPH), press CAL/CLR switch (1). In this condition, continue to drive the machine, and if the display changes to the time display sfter approx. 30 seconds, the procedure is completed. 5. Move the machine to a safe place and stop the engine. 6. Start the engine again. 7. Move the dump lever as follows: FLOAT -> RAISE -> LOWER -> FLOAT. 1. Empty the dump body.
