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. |
Input from the steering sensor is used to determine the desired turning radius. This input is a control parameter to calculate the speed differential of the drive wheels during turns. The machine control software requires three calibration points to be established for the sensor. The following procedure sets the calibration points.
Perform the calibration procedure under any of the following conditions:
- The steering sensor has been replaced.
- The transmission ECM has been replaced.
- The speed differential between the drive wheels during turns causes one of the wheels to drag.
The following calibration procedure can be done on the machine display. The right and left sensors must be calibrated independently.
