PR-1000 PAVEMENT PROFILER Transporting The Machine Caterpillar

The following procedures are to prepare the machine to transport it as a 10-foot load. If a 12-foot load is allowable, the averaging ski beams may be left in place, but the other grade sensing components and the wheel assemblies on the front of the averaging ski beams must be removed.

1. Park the machine on level grade and shut both engines down.

2. Remove the elevation sensors from their mounts and install them in the shipping mounts on the handrails.

3. Remove the grade sensing wheel assemblies from the cutter.

4. If optional averaging skis are installed, remove the support brackets, feeler rods and guide wands. Attach a lifting device to one averaging ski beam, disconnect the beam guide from the mainframe, remove the outside retainer from the beam mounting bracket, slide the beam off the mounting bracket, then lift the beam away. Install the retainer on the mounting bracket, then remove the mounting bracket from the leg yoke. If applicable, remove the averaging ski and mounting bracket from the other side.

DISENGAGE THE CUTTER CLUTCH, LOCK THE CLUTCH CONTROL AT "OUT" AND SHUT THE CUTTER ENGINE (ENGINE A) DOWN BEFORE WORKING ON THE CUTTER. SERIOUS INJURIES CAN RESULT FROM INADVERTENT STARTING OF THE CUTTER.

5. Disconnect the quick-disconnect couplings in the hoses for the moldboard cylinders, the cutter door cylinder and the spray bars on the cutter.

6. Disconnect the u-joint drives, one at each end of the power unit drive.

7. Unplug the cutter housing light wires.

8. Start engine B (AVSpare 3208), raise the mainframe enough for the cutter to clear the cutter shipping skid, position the skid under the cutter, then lower the mainframe until the cutter is resting on the skid.

9. Remove the four pins that connect the cutter to the mainframe, then raise the mainframe to clear the cutter.

10. Turn the front track to the far left limit.

LOWER CONVEYOR LIFT CONTROL VALVE

11. Use the lower conveyor lift control valve to raise the front of the lower conveyor, then move the cutter forward and out the left side of the machine.

12. Set the front track overdrive control at "On" and the rear track overdrive control at "Off", move the emergency and parking brake control to "Off", then carefully back the machine onto the trailer. Keep the mainframe as low as possible.

BE PARTICULARLY ALERT WHILE LOADING THE MACHINE. IF THE TRACK PUMP CHARGE PRESSURE DROPS BELOW THE REQUIRED LIMIT FOR PUMP SWASHPLATE CONTROL, THE INHERENT HYDROSTATIC TRANSMISSION "DYNAMIC" BRAKING CAPABILITY WILL BE LOST AND THE MACHINE WILL "RUN AWAY" DOWN THE LOADING RAMP. YOU MUST REACT INSTANTLY TO MOVE THE EMERGENCY AND PARK BRAKE CONTROL TO "ON" TO AVOID A RUNAWAY. BRACE YOURSELF FOR A " QUICK" STOP ANYTIME THE EMERGENCY AND PARK BRAKE CONTROL IS MOVED TO "ON" WITH THE MACHINE MOVING.

13. After the machine is in position on the trailer, MOVE THE EMERGENCY AND PARK BRAKE CONTROL TO "ON", lower the mainframe evenly to the lower limit, install the shipping supports on the upper conveyor, lower the conveyor onto the supports, then shut engine B (3208) down. Lower the forward console cover.

14. Tie the machine down.

15. Load the cutter, grade sensing wheel assemblies and, if applicable, the optional averaging ski assemblies onto a second trailer.

Unloading The Machine From A Trailer

1. Remove the tie-downs.

2. Check the machine visually for any shipping damage.

3. Check the oil and coolant levels of engine B (AVSpare 3208) and the hydraulic oil level. Add oil or coolant as needed.

4. Unlock the forward console top cover, swing the cover up to expose the control panel, then start engine B (see the starting instruction plate on the console).

5. Raise the upper conveyor slightly and remove the shipping supports.

6. Set the overdrive controls at "Off", move the emergency and park brake control to "Off", then carefully drive the machine off the trailer. Keep the mainframe as low as possible.

7. Unload the cutter, grade sensing wheel assemblies and, if applicable, the optional averaging ski assemblies from the second trailer. Install the cutter (see page 4-10), the grade sensing wheel assemblies (see page 4-12) and/or the optional averaging ski assemblies (see page 4-12).
