Graco AA2000 manual Ground according to the manufacturer’s recom- mendations

Static electricity is created by the flow of fluid through the pump and hose. If every part of the equipment is not properly grounded, sparking may occur, and the system may become hazardous. Sparks can ignite fumes from solvents and the fluid being sprayed, dust particles and other flammable substances, whether you are pumping indoors or outdoors, and cause a fire or explosion, serious injury, and property damage.

Sparks may also occur when plugging in or unplug- ging a power supply cord. Do not plug in or unplug any power supply cords in the spray area when there is any chance of igniting fumes still in the air.

If you experience any static sparking or feel even a slight shock while using this equipment, stop spray ing immediately. Check for proper grounding of the entire system. Do not use the system again until the cause of the problem is identified and corrected.

Grounding

To reduce the risk of static sparking, ground the pump and all other equipment used or located in the spray area. Check your local electrical code for detailed grounding instructions for your area and type of equipment and be sure to ground all of the following equipment:

1.Pump: use a ground wire and clamp as instructed in your separate pump instruction manual.

2.Air, fluid, and hydraulic hoses connected to the pump: use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity. Refer also to Hose Grounding Continuity, below.

Air compressors and hydraulic power supplies:

ground according to the manufacturer’s recom- mendations.

4.Spray gun: obtain grounding through connection to a properly grounded fluid hose and pump.

5.Fluid suppfy container: according to local code.

6.Object being sprayed: according to local code.

7.All solvent pails used when flushing, according to local code. Use only metal pails, which are con- ductive. Do not place the pail on a non-conduc- tive surface, such as paper or cardboard, which interrupts the grounding continuity.

8.To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a grounded metal pail, then trigger the gun.

Flushing Safety

To reduce the risk of fluid injection injury, static spark- ing, or splashing, follow the Pressure Relief Proce- dure on page 3, and remove the spray tip before flushing. Hold a metal part of the gun firmly to the side of a grounded metal pail and use the lowest pos- sible fluid pressure during flushing.

Ventilate the Spray Booth

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly ventilated spray booth.

Never operate the spray gun unless the ventilating fans are operating.

HOSE SAFETY

High pressure fluid in the hoses can be very danger- ous. If the hose develops a leak, split or rupture due to any kind of wear, damage or misuse, the high pres- sure spray emitted from it can cause a fluid injection injury or other serious injury or property damage.

All fluid spray hoses must have a spring guard on both ends! The spring guards help protect the hose from kinks or bends at or close to the coupling which can result in hose rupture.

Tighten all fluid connections securely before each use. High pressure fluid can dislodge a loose cou- pling or allow high pressure spray to be emitted from the coupling.

Never use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or movement of the hose couplings. If any of these conditions exist, replace the hose immediately. Do not try to recouple high pressure hose or mend it with tape or any other device. A repaired hose cannot contain the high pressure fluid. 4 307-947

Handle and route hoses carefully. Do not pull on hoses to move equipment. Do not use fluids or sol- vents which are not compatible with the inner tube and cover of the hose. Do not expose Grace hose to temperatures above 180” F (82” C) or below -40” F (-40” C).

Hose Grounding Continuity

Proper hose grounding continuity is essential to main- taining a grounded spray system. Check the electrical resistance of your air and fluid hoses at least once a week. If your hose does not have a tag on it which specifies the maximum electrical resistance, contact the hose supplier or manufacturer for the maximum resistance limits. Use a resistance meter in the appro- priate range for your hose to check the resistance. If the resistance exceeds the recommended limits, replace it immediately. An ungrounded or poorly grounded hose can make your system hazardous. Also read FIRE OR EXPLOSION HAZARD.
