DOUBLE INSULATION CONSTRUC- TION
Your unit is double insulated to help pro- tect against electric shock. Double insula- tion construction consists of two separate “layers” of electrical insulation instead of grounding. Tools and appliances built with a double insulation system are not in- tended to be grounded. No grounding means is provided on this unit, nor should a means for grounding be added to this unit. As a result, the extension cord used with your unit can be plugged into any standard 120 volt electrical outlet.
Safety precautions must be observed when operating any electrical tool. The double in- sulation system only provides added pro- tection against injury resulting from an inter- nal electrical insulation failure.
WARNING: All electrical repairs to this unit, including housing, switch, motor, etc., must be diagnosed and repaired by an authorized service dealer. Replace- ment parts for a double insulated appliance must be identical to the parts they replace. A double insulated appliance is marked with the words “DOUBLE INSULATION” or “DOUBLE INSU- LATED.” The symbol (square within a square) 
may also be marked on the ap- pliance. Failure to have the unit repaired by an authorized service dealer can cause the double insulation construction to become ineffective and result in seri- ous injury.
