Autonomous - Mode Lamps (If Equipped)
 |
|
While operating in autonomous mode, the machine may move without warning. Serious injury or death may occur. Maintain a safe distance from the machine. Personnel who may need to work in the area of an autonomous machine must understand the external autonomous mode indicator lights and job site procedures. Approach the machine when conditions are safe. |

The mode lamps for the Command for Hauling system are on the rear of the machine. Left lamp (4) is RED, middle lamp (5) is GREEN, and right lamp (6) is BLUE. | |
The mode lamps signal the status of the autonomous system as follows:
Green Flashing Signal - Manual Active Mode. Minestar clearance to approach and access the machine. The machine can be manually operated from the operator station (cab).
Blue Continuous Signal - Autonomous Enabled Mode. Operator/personnel need to move away from the machine. The machine can be put in Autonomous Active Mode by a Minestar operator.
Blue Flashing Signal - Autonomous Active Mode. Do not approach/access the machine. The machine can be remotely operated by a Minestar operator.
Blue Flashing Signal and Red Flashing Signal - Autonomous Stop (A-STOP) Mode. Do not approach/access the machine. A-STOP activated by personnel. Machine will remain in Autonomous Enabled Mode during the activation of the A-STOP. When the A-STOP is activated, the service brakes will engage, and the engine will remain running.
Green Continuous Signal - Manual Enabled Mode. Minestar clearance to approach and access the machine. The machine can be put in Manual Active Mode by the machine operator.
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.
Note: Keep the hoist control in the FLOAT position during the loading of the machine. Also, keep the hoist control in the FLOAT position when the machine travels.
Use the service brake pedal to stop the machine. See Operation and Maintenance Manual, "Stopping the Machine" for further information.
Move the transmission control to the P position.
Refer to Operation and Maintenance Manual, "Operator Controls" for more information on the hoist control, service brake pedal and transmission control.
The operator of the machine should stay in the cab while the truck is being loaded.
Do not load any material on the canopy of the dump body.
The Truck Payload System calculates the weight of the material as the material is being loaded into the truck.
A new payload cycle starts when the truck finishes dumping the previous payload and the truck dump body is fully down.
Do not move the transmission control before the last portion of the 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 Truck Payload System 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 pressure stabilizes and the truck is full enough to get an accurate weight.
Payload Status Lamps (If Equipped)

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 Advisor screen 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 payload status lamps will begin to flash. The Advisor screen will display "Last Pass".
- When the payload weight reaches 95 percent or more of the target weight, the red lamps will stay on continuously and the Advisor screen will display "Fully Loaded".
- The payload measurement system measures the weight of the load again once the truck has exited the load site. The payload status lamps will turn off and the Advisor screen will display the "Payload" message and the final payload weight.
- The payload information automatically disappears from the Advisor screen after the load has been measured. The Advisor screen then returns to the default mode.
External Payload Display (If Equipped)

|
External payload display | |
- As the truck is being loaded, the external payload displays will display the weight of the material that is in the truck dump body. The "Loading" message and the payload weight will be displayed on the Advisor screen 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 Advisor screen will display "Last Pass".
- When the payload weight reaches 95 percent or more of the target weight, the Advisor screen will display "Fully Loaded".
- The payload measurement system measures the weight of the load again once the truck has exited the load site. The Advisor screen will display the "Payload" message and final payload weight.
- The payload information automatically disappears from the Advisor screen after the load has been measured. The Advisor screen then returns to the default mode. The external payload displays will continue to display the payload until the payload is dumped.
Note: The external payload display receives data through the VIMS telemetry port.
- Do not load the machine on a surface that has a slope of more than 5 percent.
- The information may not be accurate if the suspension cylinders are not properly charged.
- Do not allow the operator of the loading machine to press with the loading tool on the 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 VIMS after any of the suspension cylinders are serviced. Calibrate VIMS 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 body.
- The information will not be accurate if the truck is loaded with a conveyor. If the truck is loaded with a continuous flow, 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 VIMS 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 Advisor screen displays the final weight.
- Do not ignore fault codes.
Refer to the Systems Operation, Troubleshooting, Testing and Adjusting, KENR9023, "793F and 797F Off-Highway Truck VIMS" for additional information.

Do not use the retarder control as a parking brake or to stop the machine. |
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 height 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 from snow. Also, roads can be slick from being wet. Reduce the speed of the machine to compensate for poor ground conditions.
Never coast down a grade in neutral. Always keep the transmission control in a forward selection. When the machine speed is greater than
When you approach a downgrade that is long or steep, the Automatic Retarder Control (ARC) Switch should be in the ON position.
If the machine builds up excessive speed, use the service brake to reduce vehicle speed.
See Operation and Maintenance Manual, "Retarding" in this Section for further information.

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 certain that no personnel are near the dump area.
Be sure that the area is free of power lines or overhead obstructions.
Only raise the body when the machine is on level ground.
Position the machine on level ground. Stop the machine and park the machine. See Operation and Maintenance Manual, "Stopping the Machine"for the recommended procedure.
Make sure that the machine is at the location to dump and move the transmission control to the P position.
Note: If the transmission control is not in the P position, the machine may roll.

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. |
Make sure that the machine is at the location to dump. Only raise the dump body when the machine is on level ground.
Move the hoist control to the RAISE position and increase the engine speed. As the hoist cylinders approach full extension, reduce engine speed. Leave the hoist control in the RAISE position until the body is completely raised.
Operating this machine with the body raised is abusive and may result in permanent frame damage. Limit machine movement with body raised.
If necessary, move the transmission control to the 1 position and slowly drive the machine forward until the machine is clear of the load.
This machine was not designed to spread material effectively. Use an appropriate machine for spreading.
Move the hoist control to the FLOAT position to lower the body. Leave the hoist control in the FLOAT position until the body is completely lowered.
Note: This machine is equipped with an automatic SNUB feature that activates just before the body is completely lowered. This reduces the FLOAT speed to prevent the body from contacting the frame too hard. Leave the hoist control in the FLOAT position until the body is completely lowered to allow the SNUB feature to soften the impact of the body.
Note: If equipped, verify that the rear cab access walkway handrail, fall protection rails, and folding walkways are in the stored position before lowering the body.
Completely lower the body before you pull out for the return trip.
The transmission will not shift into the reverse gear while the dump body (bed) is being raised or the hoist control is in the RAISE position or in the LOWER position.
If the transmission control is in the R position and the hoist control is moved to the RAISE position or to the LOWER position, the machine will promptly shift to the P position. If the reverse neutralizer must be bypassed, see "Shifting into REVERSE with the Body Raised" for the procedure.
The reverse neutralizer has no effect on the engagement of the forward gears.
Shifting into REVERSE with the Body Raised
When the body (bed) is raised, perform the following steps to return the transmission control to the R position:
- Move the hoist control to the HOLD position.
- Move the transmission control to the N position.
- Pause for 3 seconds.
- Move the transmission control to the R position.
