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
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 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 (2.5mm2) 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.

parts.
•See Technical Specifications in all equipment manuals for materials of
construction. Consult the solvent manufacturer for information and
recommendations about compatibility.
