Rotor movement can cause injury or death. Stay clear of the rotor when the engine is running. Shut off the engine before performing any service on the rotor or on the rotor housing.

Disengage the rotor before attempting to free jammed side plates. Working around the moving rotor with tools to clean or free the side plates can result in accidental contact with the rotor and cause serious injury or death.

The life of the rotor bits will vary considerably with the type of material that is being cut. The rotor bits wear differently with ambient temperatures and speed of operation. Check the bits periodically during the day. If the rotor bits are worn, nonrotating or broken, replace the bit.

The wearing of the rotor bits can be uneven if the cutting of long stretches of material is not as wide as the rotor. The wearing of the rotor bits can be uneven if the machine is cutting asphalt that is on top of concrete.

Uneven wear to the rotor bits may occur during cross slope cutting. The rotor bits should be checked for uneven wear. Replace the rotor bits if uneven wear has occurred. The rotor bits must be of the same length in order to have an accurate cut.

Replace

Note: The rotor bits are installed in tool holders. The rotor bits are driven in. The rotor bits are removed with tools that use a simple knock out method. The tool holders are welded to mounting blocks on the flighting.

1. Raise the machine to service height. Raise the service door for the rotor.

2. With the engine rpm at LOW IDLE, disengage the rotor.

4. Engage a remote stop switch.

5. Turn the battery disconnect switch to OFF. Remove the key.

   Note: Clean the rotor around the bits that need to be removed.

   Note: The bits may be removed by three methods:

   • pneumatic remover

   • manual remover

   • hammer and punch
