HARNESS AS-MOTOR 3089222 - Caterpillar

Do not use the retarder control as a parking brake or to stop the machine.
Pay attention to your surroundings. Keep a safe distance from any machines in front of your machine.Do not drive over unprotected power cables. Do not drive under low power cables.Know the maximum height of the machine. Know the maximum width of the machine. Maintain proper clearances.Always travel with the hoist control in the FLOAT position. Shift to the top speed that is anticipated. All further shifts will be automatic.During normal operation, use the service brake for all normal braking.Roads can be slick from ice or from snow. Also, roads can be slick from being wet. Reduce the speed of the machine in order to compensate for poor ground conditions.Travelling Down a Grade
Never coast down a grade in NEUTRAL. Always keep the transmission in gear. When the machine speed is greater than 2 km/h (1 mph), the Power Train Electronic Control System will not allow you to shift from forward gear into NEUTRAL or into REVERSE.
Illustration 1 g00688644When you approach a downgrade that is long or steep, Automatic Retarder Control (ARC) Switch (1) should be in the ON position. Select the desired gear before you start the downgrade. The actual gear of the transmission should also match the selected gear before you start the downgrade.Determine the proper gear for the conditions, the load, and the downgrade. If you do not know the proper gear, use the common practice of selecting the gear that is required to go up the grade when the machine is loaded.See Operation and Maintenance Manual, "Retarding" in this Section for further information.Preventing Overspeed
Illustration 2 g00688642If the machine builds up excessive speed, use the retarder control (lever) (2) in order to reduce the vehicle speed. If braking force is needed, use the service brake.Note: If the engine reaches 2300 rpm and the transmission is in the same gear as the transmission direction and speed control, the transmission will upshift one gear. If the transmission is in the top gear, the torque converter lockup clutch will disengage.
Do not shift into the NEUTRAL position and do not freewheel down a grade.If the brake oil temperature gauge enters the red range, reduce the travel speed or stop the machine until the oil cools. This will prevent damage to the brake components.
