GROUNDING INSTRUCTIONS
This appliance must be grounded while in use to protect the operator
from electric 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 lug, 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.
NOTE: The use of an adapter is not authorized in Canada.
