Grounding and Electric Requirements
Grounding Instructions
This product must be grounded. In the event of an eletrical 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 groundingwire 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 orinances.
Improper installation of the grounding plug can result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not connect the green grounding wire to either flat blade terminal. The wire with insulation having a green outer surface with or without yellow stripes is the grounding wire and must be connected to the grounding pin. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided. If the plug will not fit the outlet, have the proper outlet installed by a qualified electrican.
The sprayer cord includes a grounding wire with an appropriate grounding contact.

The sprayer requires for type475:
100-120Vac, 50 Hz, 11A, 1 phase, circuit with a grounding receptacle The sprayer requires for type 470:
220-240Vac, 50Hz,11A, 1 phase, circuit with a grounding receptacle.
Never use an outlet that is not grounded or an adapter.

Do not use the sprayer if the electrical cord has a damaged ground contact. Only use an extension cord with an undamaged ground contact.

Smaller gauge or longer extension cords may reduce sprayer performance.
Spray gun: ground through connection to a properly grounded fluid hose and pump.
Fluid supply container : follow local code.
Solvent and Oil-based fluids: follow local code. Use only conductive metal pails placed on a grounded surface such as concrete. Do not place the pail on a nonconductive surface such as paper or cardboard, which interrupts grounding continuity.
