Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation
point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these
symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard
symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
WARNING
DUST HAZARD
Grinding concrete and other surfaces can create dust that contains hazardous substances.
To reduce the risk of serious injury:
• Control the dust to meet all applicable workplace regulations.
• Wear a properly fit-tested and government approved respirator suitable for the dust conditions when
emptying collection tank or performing maintenance.
• Do not use without dust bag and filters in place.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause elec-
tric shock.
• Turn off and disconnect power cord before servicing equipment.
• Connect only to grounded electrical outlets.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on power and extension cords.
• Do not expose to rain. Store indoors.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the equipment. Keep
cord away from heat, sharp edges, or moving parts.
• Do not use on wet surfaces.

Warnings
4TBD
GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric current. This product is equipped with a cord
having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet
that is properly installed and grounded in accordance with all local codes and ordinances.
• Improper installation of the grounding plug is able to result in a risk of electric shock.
• When repair or replacement of the cord or plug is required, do not connect the grounding wire to
either flat blade terminal.
• The wire with insulation having an outer surface that is green with or without yellow stripes is the
grounding wire.
• Check with a qualified electrician or serviceman when the grounding instructions are not completely
understood, or when in doubt as to whether the product is properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a
qualified electrician.
• This product is for use on a nominal 120V or 230V circuit and has a grounding plug similar to the
plugs illustrated in the figure below.
• Only connect the product to an outlet having the same configuration as the plug.
• Do not use an adapter with this product.
Extension Cords:
• Use only a 3-wire extension cord that has a grounding plug and a grounding receptacle that
accepts the plug on the product.
• Make sure your extension cord is not damaged. If an extension cord is necessary, use 12 AWG
(2.5 mm2) minimum to carry the current that the product draws.
• An undersized cord results in a drop in line voltage and loss of power and overheating.
