Loading The Machine Onto A Trailer

The PR-450 can be transported as an 8-foot load by removing the access ladder, removing the wheeled reference assemblies or averaging skis, and swinging the elevation sensors and supports to the front of the machine.

NOTE: DO NOT DISCONNECT THE HOSES FROM THE ELEVATION SENSORS FOR SHIPPING.

1. Remove the averaging skis or wheeled reference assemblies.

2. Remove the averaging ski pins, averaging ski guides, and the rear leg elevation scales.

3. Loosen the bolts in the flange halves that hold the elevation sensor support arms, swing the arms as far forward as possible, and retighten the flange halves.

4. Back the machine onto the trailer. Keep the mainframe as low as possible so that the center of gravity is low, but be careful not to drag the cutter at the junction of the trailer and loading ramp.

5. Lower the mainframe evenly until the cutter is resting on the trailer bed and the mainframe is level. MOVE THE EMERGENCY AND PARKING BRAKE CONTROL TO "APPLY".

6. Remove the conveyor shipping supports from their storage brackets, connect the supports to the upper conveyor, adjust the length of the supports, then lower the conveyor onto the supports.

7. Shut the engine down and install the console cover.

8. AFTER THE EXHAUST STACK HAS COOLED, loosen the clamp at the top of the muffler, turn the stack to face the front of the machine, cover the opening with tape, and tighten the clamp.
