Information:

To prevent undesired upshifting, move the selector to the gear position you are retarding in.If the machine gains too much speed while retarding, threatening engine overspeed, use the service brake until speed is reduced. If additional braking is needed, hold down the secondary brake lever. This adds more brake force.Travel at the best average speed. Do not speed up and brake down. Don't try to do all the braking at the bottom of a hill. Keep braking steady and speed under control. Should the engine still be in danger of overspeeding, move the selector one gear higher to reduce engine speed until the machine slows. Then return the selector to original position.Secondary Braking
The machines have a separate secondary braking air supply. The machine can be stopped with the secondary braking system, should a service/retarder air system failure occur. Pull the red lever on the left all the way down for emergency application of all four wheel brakes.Whenever an emergency stop is made due to any circumstance, recheck oil, fuel, air pressure, leaks, etc., and correct faults before attempting to move the machine.If brake release pressure cannot be obtained because engine will not start, see Towing Information to release rear brakes. Put blocks under wheels before leaving a disabled machine. If all air in emergency system is lost, the rear brakes will apply automatically, and remain applied.The machine can be positioned for loading and the brakes set, before shifting to neutral. Just as important, the machine can be put in gear before releasing the brakes to pull away. Engage parking brake when stationary.
To prevent damage to the parking brake, use the parking brake only for parking.
Loading With Truck Payload Measurement System (TPMS)
Use care when backing into the dump area. Stay clear of soft edges that could collapse under the machine.Lower the body (bed) COMPLETELY before pulling out on the return trip, to prevent hitting power lines, or other low hanging obstructions.
Keep the dump control in float while loading and traveling. The operator of the machine should stay in the cab of the machine, while it is being loaded.To begin the weighing process
1. Depress the service brake to stop the machine. 2. Move the transmission selector to NEUTRAL. 3. Move the parking brake switch (1) to ON, or move the retarder control lever (2) to the down position.Truck Payload Measurement System (TPMS) Calculates the weight of the material as it is being loaded into the truck. Dumping the first load into the truck before it has stopped and is in NEUTRAL could affect the accuracy of the payload weight. Putting the truck in gear and leaving the loading site before the last load has registered on the Payload Operator Display (POD) could affect the accuracy of the payload weight. The truck can be repositioned during loading, but once the truck moves more than 0.16 km (0.1 miles), TPMS will see the loading cycle as completed, and additional loader passes will not be recorded.The suspension cylinder pressures will increase sharply
