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.

Specifications

Introduction

The tamper solenoid is electronically controlled using open-loop logic. Two calibration points are required to ensure proper tamper speed control during operation. Perform the calibration procedure under any of the following conditions:

• The tamper pump has been replaced.

• The tamper solenoid has been replaced.

• The auxiliary ECM has been replaced.

• Maximum tamper speed is outside the specified range.

• The tamper bar rotates although the system is off.

The following calibration procedure can be done on the machine display.

Required Tools

Calibration Preparation
