product will be safer and do a better job at the capacity for which it was intended. DO NOT use this equipment for a purpose for which it was not intended. Industrial or commercial applications must follow OSHA requirements. ⚠WARNING WORK AREA SAFETY Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit. Cluttered, wet, or dark work areas can result in injury.
PUMP USE AND CARE Do not force the pump. Products are safer and do a better job when used in the manner for which they are designed. Plan your work, and use the correct product for the job. Check for damaged parts before each use. Carefully check that the product will operate properly and perform its intended function. Replace damaged or worn parts immediately. Never operate the product with a damaged part. Do not use a product with a malfunctioning switch.
After grounding, periodically verify continuity of electrical path to ground. Test with an ohmmeter from each component (e.g., hoses, pump, clamps, container, spray gun, etc.) to ground to insure continuity. Ohmmeter should show 100 ohms or less. Pump exhaust may contain contaminants which can cause severe injury. Pipe exhaust away from work area and personnel. In the event of a diaphragm rupture material can be forced out of the air exhaust muffler.

Assembly Instructions • • • The diaphragm pump offers high volume delivery even at low air pressure. Air-operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure in the fluid chambers. The ball check insures a positive flow of fluid. Pump cycling will begin as air pressure is applied and it will continue to pump and keep up with the demand.
Consult local building codes and electrical codes for specific grounding requirements. After grounding, periodically verify continuity of electrical path to ground. Test with an ohmmeter from each component (e.g., hoses, pump, clamps, container, spray gun, etc.) to ground to insure continuity. Ohmmeter should show 100 ohms or less. In the event of a diaphragm rupture material can be forced out of the air exhaust muffler. Do not use the pump for the structural support of the piping system.
