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.

Show/hide table

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.

Show/hide table

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.

Introduction

This procedure outlines the steps used to calibrate the speed settings for the right auger conveyor or the left auger conveyor. To check the auger conveyor speed, refer to AP1055F Asphalt Paver Machine Systems Testing and Adjusting, "Conveyor Speed (Auger)-Check".

Note: Use this procedure to set the initial current for the auger solenoids and to calibrate the material height dials. The paver must have either paddle or sonic material height sensors installed for automatic operation of the auger to function. In order to calibrate the paddle sensors, start by preparing the machine for calibration. Refer to, "Calibration Preparation". If the left auger is to be calibrated, refer to "Calibration Procedure", "Left Auger Conveyor". If the right auger is to be calibrated, refer to "Calibration Procedure", "Right Auger Conveyor".

Required Tools

Calibration Preparation

1. Drive the machine to a smooth, horizontal surface.

11. Press the down arrow on throttle control switch (13) once in order to operate the engine in low idle.
    Show/hide table

    Illustration 8	g03483124

12. Shut off the engine. Either place machine power switch (14) in the OFF position or press and hold push to start switch (12) for 3 seconds. An LED next to the push to start switch will flash when the engine is in shutdown mode.

    Note: The engine may run for several minutes when placed in the shutdown mode.

13. If the engine was shut down using the push to start switch (12), move machine power switch (14) to the OFF position.

14. Install a small piece of reflective tape (15) from Tool (A) on left auger shaft (16).

    Note: If the right auger is being tested, place a small piece of reflective tape (15) on the right auger shaft (not shown).

Calibration Procedure

1. Move machine power switch (14) to the ON position.

2. Press push to start switch (12) for 2 seconds in order to start the engine. An LED next to the push to start switch will flash when the engine is in start mode. When the engine has started, the LED will remain illuminated.

   Note: Only one attempt to start the engine is allowed per key cycle. A new key cycle will need to be done in order to restart the process.

3. Operate the engine at low idle for a few minutes.

4. Press the up arrow on throttle control switch (13) in order to place the engine in high idle. The engine speed should increase to 2200 rpm.
