Grounding Safety

Check your local electrical code for detailed grounding instructions for your area and type of equipment and be sure to ground all of this spray equipment as the following.

1Pump : Use a ground wire and ground to a good source such as the building ground source, or drive a steel spike into the ground and attach the ground wire to it.

2Fluid hoses : Use only grounded hoses to a maxi- mum of 500 FT (150M)

3Spray Gun : Connect to a properly grounded fluid hose and pump.

5Object being sprayed & Fluid supply tank : All sources should be grounded.

6Solvent pail : Use only metal pails not plastic or use the pail on a non conductive surface, such as card board or plastic sheeting .

MOVING PARTS SAFETY WARNING

•Moving parts can cause to pinch or seriously injure your fingers or other body parts.

•Keep clear of moving parts when starting or operating the pump and be sure to follow the “Pressure Relief Procedure” to prevent the pump starting accidentally.

INSTALLATION

•Install the correct spray hose and spray tips to suit the type of application.

•All fluid hoses must be properly sized and pressure rated for this equipment.

•Use only grounded fluid hoses.

•Pressure regulator - This controls pump pres sure and outlet pressure by adjusting the adjustment knob to the pump.

•Hydraulic shut off valve - This lever type valve shuts off fluid pressure from hydraulic pump.

•Suction tube filter - Removes harmful and course materials from entering pump.

•Filter manifold - Removes and filters out the impu- rities from the paint before reaching the spray tip.

•Prime valve - Releases fluid pressure from the pump, hoses and guns. Turn counter clockwise to open and clockwise to close.

•Spray Gun Make sure that gun is in good operating condition.

AIRLESS – SPRAY TECHNIQUE

Good airless-spray technique is much like conventional air spray, except that you hold the gun further from work surface, you get more coating thickness, which results in less pattern overlapping, and you use more positive action when triggering gun.

Hold the gun 10-12 in from the work, the distance varies with the covering ability of the paint, type of surface to be sprayed, and the spray pattern.

PREPARING PAINT FOR USE.

These are probably the most important steps toward trouble-free spray painting.

•Prepare the paint or other coatings according to the manufacturer’s instructions.

•If the paint has been opened before, the product should checked to make certain that it has not skinned over .

•Stir paint thoroughly to dissolve hard pigments.

•Strain the paint through a fine nylon mesh bag (available at most paint dealers) to remove particles that may clog filters, or spray tip.

•Follow the paint manufacturer’s recommendation on thinning the material to be sprayed.

•Be careful not to add too much solvent, over thinning paint makes the coating hard to control and reduces its coverage .
