PIPE AS 4809802 - Caterpillar

Use care when backing into the dump area.Stay clear of soft edges that could collapse under the machine.
Inspect the dump area before you bring in a loaded machine.Take care when you drive into the dump area. Maintain a safe distance from other machines.Avoid hitting sharp rocks.Be certain that no personnel are near the dump area.Park the machine on level ground. For the recommended procedure, refer to Operation and Maintenance Manual, "Stopping the Machine" for the machine that is being serviced.Ejecting
Illustration 1 g06226931
Illustration 2 g06222578Before you move the hoist control to EJECT position (4), make sure that the machine is at the location to dump. Also, move parking brake control (5) to the ON position, press neutral button (6).Note: If the parking brake is not engaged or if the service brake is not applied, the machine may roll backward.With the hoist control in EJECT position (4), wait until the tailgate is completely down before depressing the throttle pedal to increase the engine speed. As the ejector cylinders approach full extension, reduce the engine speed. Reduce hand pressure on the hoist control to slow the movement of the ejector plate. This may avoid damage to the ejector cylinders.When the body is empty, move the hoist control to RETRACT position (1) to retract the ejector plate and raise the tailgate. Depress the throttle pedal to increase the engine speed. As the ejector cylinders fully retract, reduce the engine speed. Reduce hand pressure on the hoist control to slow the movement of the ejector plate and the tailgate.Completely raise the tailgate before you pull out for the return trip.Note: Machine speed is limited if the tailgate is down and/or the hoist control is not in first HOLD position (2).Reverse Neutralizer
The machine will not shift into reverse while the tailgate is down or the hoist control is in EJECT position (4) or in RETRACT position (1).When the transmission is in reverse and the hoist control is moved to EJECT position (4) or to RETRACT position (1), the transmission will promptly shift to neutral. If the machine is on a slope, apply the brakes to stop the machine from moving. If the reverse neutralizer must be bypassed, refer to "Shifting into Reverse with the Tailgate Down" for the procedure.The reverse neutralizer has no effect on the forward gears. If the situation is required, the forward gears can be engaged from the NEUTRAL position or the REVERSE position.Shifting into Reverse with the Tailgate Down
When the tailgate is down, perform the following steps to return the transmission control to the REVERSE position:
Move the hoist control to second HOLD position (3).
Press neutral button (6) on the transmission control.
Pause for three seconds.
Press the reverse button on the transmission control.
