grounding instructions
This appliance must be grounded while in use to protect the operator from electrical shock. The appliance is equipped with a 3-conductor cord and 3-prong grounding-type plug to fit the proper grounding-type receptacle. The appliance has a plug that looks like the plug in drawing (1). An adapter, as in drawing (2), should be used for connecting the appliance plug to two-prong receptacles. The grounding tab which extends from the adapter must be connected to a permanent ground such as a properly grounded outlet box as shown in drawing (3) using a metal screw.
EXTENSION CORDS
Use only 3-wire extension cords which have 3-prong grounding-type plugs and 3-pole cord connectors that accept the plug from the appliance. Use only extension cords that are intended for indoor use. Use only extension cords having an electrical rating not less than the rating of the appliance. Do not use damaged extension cords. Examine extension cord before using and replace if damaged. Do not abuse extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp edges.
