Why aren all radial arm saws retofitable?
Only certain 10-inch radial arm saw models manufactured since 1977 can be equipped with the new guarding system kit. The retrofit kit is only compatible with certain types of motor hub and handle/bevel locking mechanisms to which the new guarding system is attached. The new guarding system cannot be adapted to the other Craftsman radial arm saws for a number of reasons. In some cases the saw motor is not compatible with the guarding system mounts and the bevel-index locking mechanisms and handles will not accommodate the trigger and handle assembly of the new guarding system. In many models, saws would require new legs, bases and table assemblies to allow proper positioning of the modified fence. These saws would have to be substantially rebuilt to permit the safe and proper attachment of a fully functional new guarding system.
