Air Pressure Governor Override (Earlier Machines)
Override Button - Higher than normal air pressure may be needed to release the parking/emergency brake system on earlier machines.Push the button to override the air pressure governor. This allows air pressure to increase to 1030 kPa (150 psi). Service Brake
Apply - Push the pedal down to apply the service brakes. Release - Release the pedal to release the brakes.Accelerator Pedal
Increase Engine Speed - Push down the pedal to increase engine speed. Decrease Engine Speed - Release the pedal to decrease engine speed. Stop Engine - Lift the toe of the pedal to stopped detent to stop the engine. High Idle Throttle Lock
Engage - Push the button in. The engine will go to high idle speed and remain there. Release - Pull the button out or tap the service brake to return to manual control of the engine speed.Use the Throttle Lock on long hauls where fatigue can result from accelerator pedal use.Transmission Range Selector
The machine must be stopped, and the engine at low idle, when changing direction.
Forward (1.) - The transmission will shift automatically between 2nd and any other speed (3rd through 8th) selected in the automatic range.Manual shifting is not recommended during normal operation cycles.1st speed is selected manually.Select the highest of the 8 forward speeds that is practical for your application. Neutral (2.) - Move the lever to NEUTRAL when parking the machine, or when starting the engine. Reverse (3.) - For reverse, move the lever to the front of the console.Transmission Neutral Lock

Do not lock the differential with a wheel spinning.
Decrease the rpm momentarily when locking the differential. Lock - Push the pedal down to lock the differential. This will help prevent wheel slippage. Use it when loading or on soft or wet ground. Unlock - Release the pedal to unlock the differential.Turning the machine slightly or decreasing rpm momentarily may be necessary to aid in unlocking.
Retarder Engage (1.) - Pull the lever to engage the retarder. The farther the lever is pulled, the greater the braking action. Disengage (2.) - Push the lever to stop the braking action.
The retarder must be used at least once a week to keep the seals lubricated.
Anticipate retarder use. It requires 3 or 4 seconds for the retarder to engage after the lever is moved.
