Diesel engine exhaust contains products of combustion which may cause personal injury. Always start and operate the engine in a well ventilated area, and, if in an enclosed area, vent the exhaust to the outside. |
|
|
Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts. Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified. The machine must be parked on a level surface and the engine stopped. Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine. |
|
|
Personal injury or death can result from sudden machine movement. Sudden movement of the machine can cause injury to persons on or near the machine. To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine. |
|
|
Injury to personnel can result if they are not in the operator's view. Allow only essential personnel near the machine, and make sure the personnel are in the operator's view when testing, to prevent injury. Make sure checks are done in an open area. |
|
|
To prevent injury or death, never work under a machine while a test is being performed. |

| The drag conveyor sprocket shaft speed. | 119 ± 15 rpm | |
| Time required for conveyor to make a complete revolution. | 10.5 ± 1.5 seconds | |
The conveyor solenoids are electronically controlled using open-loop logic. The minimum current and maximum current must be calibrated to ensure proper conveyor speed control during operation. Perform the calibration procedure under any of the following conditions:
- The auxiliary pump has been replaced.
- A conveyor solenoid has been replaced.
- The machine ECM has been replaced.
- Maximum conveyor speed is outside the specified range.
- A conveyor moves when the system is off.
- Conveyor movement is erratic immediately after conveyor movement is initiated.
The following calibration procedure can be done on the machine display. The right and left solenoids must be calibrated independently.
