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 drag conveyor or the left drag conveyor. To check the drag conveyor speed, refer to AP1055F Asphalt Paver Machine Systems Testing and Adjusting, "Conveyor Speed (Drag)-Check".

Required Tools

Test Preparation

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

2. Move propel lever (4) to the NEUTRAL position.

3. Press parking brake switch (5) in order to change the status of the parking brake to "engaged". When the parking brake status is "engaged", LED (2) next to the parking brake switch will be illuminated.

4. Use travel mode switch (3) to select the PAVE mode. When the travel mode switch is set to PAVE mode, an LED next to PAVE symbol (1) will be illuminated.

15. Install a small piece of reflective tape (17) from Tool (A) on left conveyor sprocket shaft (18).

    Note: If a photo tachometer is not available, this calibration can be performed by using a stopwatch and timing the movement of the conveyor slats. Choose a conveyor slat and clearly mark the conveyor slat with chalk or paint.

16. Install another small piece of reflective tape from Tool (A) on the right conveyor sprocket shaft (not shown).

17. If a photo tachometer is not available, this calibration can be performed by using a stopwatch and timing the movement of the conveyor slats. Choose a conveyor slat (19) and clearly mark the conveyor slat with chalk or paint (20).

Calibration Procedure

1. Move machine power switch (11) to the ON position.

2. Press push to start switch (9) 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 (10) in order to place the engine in high idle. The engine speed should increase to 2200 rpm.
