GROUNDING INSTRUCTIONS
• This floor finishing machine should be grounded while in use to protect the operator from electric
shock. The machine is equipped with a three-prong grounding type attachment plug to fit the proper
grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding
wire. Never connect this wire to other than the grounding blade.
• Floor Finishing Machines Rated Less Than 150 Volts - If the machine is provided with an attachment plug as shown in Sketch A it is intended for use on a 120-volt (nominal) circuit. If a properly
grounded receptacle as shown in Sketch A is not available, an adapter as shown in Sketch C is
available and should be installed as shown in Sketch B if the outlet box that houses the receptacle
is grounded. Be sure to fasten the grounding tab with the faceplate
