Z87.1-1989 standards. Safety glasses are available at your Craftsman retailer or local hardware store. Also wear ear/hearing

protection when operating this unit. Wear a face or dust mask if the operation is dusty. Long sleeve shirts are recommended.

• Use the right tool. Only use this tool for its intended purpose.

• Turn off all controls before unplugging.

• Store the unit indoors. Lock up the unit to prevent unauthorized use or damage and to keep out of the reach of children.

ELECTRICAL SAFETY WARNINGS

• Since the tool is double-insulated, a2-wire extension cord (an extension cord without a ground) may be used. A 3-wire

extension cord (an extension cord with a ground) that uses a

NEMA-type connector (parallel blade, U ground) is recommend-

ed. Extension cords are available from your local retailer. Use only round-jacketed extension cords approved for outdoor use.

• This tool is double-insulated. Repair or replace damaged cords.

• To reduce the risk of electrical shock, this appliance has a polarized plug (one blade is wider than the other) and will require

the use of a polarized extension cord. The appliance plug will fit into a polarized extension cord only one way. If the plug does

not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A

polarized extension cord will require the use of a polarized wall outlet. This plug will fit into the polarized wall outlet only one

way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to

install the proper wall outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug in any way.

insulated appliance requires extreme care and knowledge of the system and should be done only by qualified service

personnel. Replacement parts for a double-insulated appliance must be identical to the parts they replace.
