ELECTRICAL

(Model MC20115) This floor machine is designed to operate on a standard 15 amp. 120 volt, 60 hz,

AC circuit. Voltages below 105 volt AC or above 125 volts AC could cause serious damage to the

motor.

(Model MC20230) This machine is designed to operate on a standard 16 amp type L fused 230 volt,

50 hz, AC circuit. Voltages below 200 volts AC or above 250 volts AC could cause serious damage

to the motor I.E.C. Class 1.

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 screw.

(unlock it), then release it slowly.

- To lift the brush, press the pedal down until lift mechanism engages.
