The improved waste handling arrangement (if equipped) contains one new 365-5075 Seal Guard As. The new seal guard assembly prevents debris from wrapping around the shaft of the fan motor. The new seal guard assembly will improve the service life of the fan motor in the field.
The new 365-5075 Seal Guard As is now part of the 211-5088 Waste Handling Ar (if equipped). The new seal guard assembly is adaptable to machines RJS1-UP.
Use the following procedure to update the earlier machines with the new 365-5075 Seal Guard As.
