Move transmission direction and speed control lever (4) to the NEUTRAL position. Move parking brake switch (3) to the ON position. Note: Do not dump the first load into the truck before the truck has stopped and the transmission is in the NEUTRAL position. Loading the truck too soon may affect the accuracy of the payload weight.Note: Do not put the machine in gear before the last load has been recorded on the display. This may affect the accuracy of the payload weight.Note: The truck can be repositioned during loading. If the truck moves more than 160 m (525 ft), the TPMS will believe that the loading cycle is completed. Also, the additional loader passes will not be recorded.The TPMS measures the load by using the pressures of the suspension cylinders. The green lights that are located on the side of the machine will activate. Also, the green light on the payload operator display will activate and the weight will be displayed.The truck may bounce during loading which will delay the display of the payload.The display will show no weight until the suspension cylinder pressures stabilize and the truck is full enough to get an accurate weight.When the TPMS determines that 95 percent of the target weight will be achieved with another bucket load, the red lights that are located on the side of the machine will begin to flash. When the payload weight reaches 95 percent or more of the target weight, the red lights will stay on continuously and the payload operator display will display "FULLY LOADED".The external red lights go off and the final payload weight is held on the display when the truck has moved more than 160 m (525 ft).Refer to Service Manual, SENR4733, "Truck Payload Measurement System (with Real Time Clock)" for additional information.Hauling
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.When you are on a downgrade, the repeated, intermittent application of the service brake control or of the manual retarder lever can reduce the air pressure. This can cause the air pressure to drop below the operating pressure.Note: The manual retarder lever should not be used to park the machine.
Illustration 4 g00615954When you approach a downgrade that is long or steep, switch (1) for the automatic retarder control (ARC) should be in the ON position. When you drive down a grade, use the same gear range that is used for driving up a grade when the machine is loaded. The transmission direction and speed control lever should be in 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.
