Take care when you drive into the loading area. Maintain a safe distance from the machine in front of your machine.
Avoid hitting sharp rocks and overflow.
Park the machine on level ground. See Operation and Maintenance Manual, "Stopping the Machine" for the recommended procedure.
The operator of the machine should stay in the cab while the truck is being loaded.
Note: Keep hoist control (1) in the FLOAT position during the loading of the machine. Also, keep the hoist control in the FLOAT position when the machine travels.

DO NOT load material on the canopy. Loading material on the canopy can exceed the hoist capacity and can cause machine damage. |
- Use service brake pedal (2) to stop the machine. See Operation and Maintenance Manual, "Stopping the Machine" for further information.
- Move transmission control (3) to the PARK position.
Truck Payload Measurement System (If Equipped)
Do not dump the first load into the truck before the truck has stopped and the transmission control is in the PARK position. Loading the truck too soon may affect the accuracy of the payload weight.
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.
The truck can be repositioned during loading. If the truck moves more than
The TPMS measures the load by using the pressures of the suspension cylinders.
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.

Payload status lamps | |
- As the truck is being loaded, the green payload status lamps will illuminate. The "LOADING" message and the payload weight will be displayed on the message center inside the cab.
- When the payload measurement system determines that 95 percent of the target weight will be achieved with another pass with the loading equipment, the red lamps will begin to flash. The message center will display "LAST PASS".
- When the payload weight reaches 95 percent or more of the target weight, the red lights will stay on continuously and the message center will display "FULLY LOADED".
- The payload measurement system measures the weight of the load again once the truck has exited the load site. The external red lights go off and the message center will display the "PAYLOAD" message and the final payload weight when the truck has moved more than
160 m (525 ft) . - The payload information automatically disappears from the message center after the load has been measured. The message center then returns to the default mode.
- Do not load the machine on a surface that has a slope of more than 5%.
- The information may not be accurate if the suspension cylinders are not properly charged.
- Do not allow the operator of the loader to press with the loader bucket on top of the last load.
- Do not move the truck more than
160 m (525 ft) while the truck is being loaded. - Do not move the hoist control while the truck is being loaded.
- Calibrate the TPMS after components are replaced. Calibrate the TPMS after substantial changes are made to the empty weight of the truck. There is a substantial change in weight when wear plates are added to the truck body.
- The information will not be accurate if the truck is loaded with a conveyor. If the truck is loaded with a continuous feed system, the information will not be accurate. These systems do not provide an abrupt increase in the pressure of the suspension cylinders. The abrupt increase of the pressure of the suspension cylinders causes the TPMS to begin the loading cycle.
- Do not move away from the loading site before the pressures of the suspension cylinders have stabilized. Do not move away from the loading site before the message center displays the final weight.
- Do not ignore fault codes.
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 snow. Also, roads can be slick from being wet. Reduce the speed of the machine in order to compensate for poor ground conditions.
Before you approach a downgrade that is long or steep, ensure that the parameters for the Automatic Retarder Control (ARC) are set properly. Refer to Operation and Maintenance Manual, "Monitoring System". 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. Refer to Operation and Maintenance Manual, "Retarding". If you do not know the proper gear, use the common practice of selecting a gear that is required to go up the grade when the machine is loaded.
If the machine builds up excessive speed, use the service brake in order to reduce vehicle speed. This adds more brake force when the front brake control is in the ON position.
Note: If the engine reaches 2800 rpm and the transmission is in the same gear as the transmission control, the transmission will upshift one gear.
| NOTICE |

|
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. |

|
Personal injury or death can occur when backing the machine over soft edges. Use care when backing into the dump area. Stay clear of soft edges that could collapse under the machine. If the load is frozen in the machine bed and dumping is attempted on a slope, the machine can tip over causing personal injury or death. |
Inspect the dump area before you bring in a loaded truck.
Take care when you drive into the dump area. Maintain a safe distance from other machines.
Avoid hitting sharp rocks.
Be sure that no personnel are near the dump area.
Park the machine on level ground. See Operation and Maintenance Manual, "Stopping the Machine" for the recommended procedure.

|
DO NOT use the momentum of the moving truck to assist in dumping an improperly loaded truck. This can result in major structural damage to the truck. This could also result in damage to the hydraulic system. |
Before you move the hoist control to the RAISE position , make sure that the machine is at the location to dump. Also, move the transmission control to the PARK position.
Be certain that no personnel are near the dump area.
Note: If the transmission control is not in the PARK position or if the service brake is not applied, the machine may roll backward.
Move the hoist control to the FLOAT position in order to lower the truck body or the water tank. Leave the hoist control in the FLOAT position until the truck body or the water tank is completely lowered.
Note: This machine is equipped with an automatic SNUB feature that activates just before the truck body or the water tank is completely lowered. This reduces the FLOAT speed in order to prevent the truck body or the water tank from contacting the frame too hard. Leave the hoist control in the FLOAT position until the truck body or the water tank is completely lowered in order to allow the SNUB feature to soften the impact of the truck body or the water tank. The SNUB speed can be adjusted by using the ET.
Completely lower the truck body or the water tank before you pull out for the return trip. This will prevent the truck body or the water tank from hitting power lines or overhead obstructions.
The machine will not shift into the REVERSE position while the truck body or the water tank is being raised or the hoist control is in the RAISE position or in the LOWER position.
When the transmission control is in the REVERSE position and the hoist control is moved to the RAISE position or to the LOWER position, the transmission will promptly shift into the NEUTRAL position. If the machine is on a slope, apply the brakes in order to prevent the machine from moving. If the reverse neutralizer must be bypassed, see "Shifting into REVERSE with the Truck Body or the Water Tank" 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 Truck Body or the Water Tank
When the truck body or the water tank is raised, perform the following steps in order to return the transmission control to the REVERSE position:
- Move the hoist control to the HOLD position.
- Move the transmission control to the NEUTRAL position.
- Pause for three seconds.
- Move the transmission control to the REVERSE position.
