Operation
Grounding
The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.
Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground exceeds 29 megohms, replace hose immediately.
Spray gun: ground through connection to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code. Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.
To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun/dispense valve firmly to the side of a grounded metal pail, then trigger the gun/valve.
The sprayer cord includes a grounding wire with an appropriate grounding contact.
The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Operation
TI C
Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.
Extension Cords: Use an extension cord with an undamaged ground contact. If an extension cord is nec-
essary, use a 3-wire, 12 AWG (2.5 mm2) minimum.
NOTE: Smaller gauge or longer extension cords may reduce sprayer performance.
