Motor Brushes
1)Unplug tool before remov- ing brushes.
2)Inspect brushes regularly (at least every 100 hours of running time). If brushes are less than 1/8" long, replace them immediately.

6)After second set of brushes are worn down, return the tool to a qualified repair technician who is familiar with the repair of electric tools, a qualified service organization or Master Appliance Corp.'s Repair Department for interior cleaning, dressing of the commutator, or whatever maintenance is required.
7)Always use original Master Appliance Corp. replace- ment parts.
