Airless Paint Systems

Operation

STARTING UP

1.Learn the functions of the controls (see “How to Spray / Important Components” for more information).

2.Prepare the Material

a.Prepare the material according to material manufacturer's recommendations.

b.Place the pump or suction tube into the material container.

3.Start the sprayer.

a.Prime/PR Valve must be open in the priming position.

b.Pressure Control Knob must be in low pressure position.

c.Follow procedure under “How to Flush,” page 5, Steps 6 to 12.

To stop the unit in an emergency or

before performing any service or maintenance procedure follow the Pressure Relief Procedure on page 3 to relieve the fluid pressure.

4.Prime the pump.

a.Allow pump to operate until paint comes from gun.

b.Release the trigger and engage the gun safety latch.

c.Turn Prime Valve OPEN to the prime position ensuring the pressure is released from the system.

d.Turn Pressure Control Knob to minimum pressure.

e.Install spray tip onto gun.

f.Close the prime valve to the pressure position.

g.Turn the pressure control knob to desired spray pressure.

h.Disengage the gun safety lock and you are ready to start spraying.

if you spray paint into the paint

bucket, always use the lowest spray pressure and maintain firm metal-to- metal contact between gun and container.

5.Adjust pressure.

a.Turn the Pressure Control Knob clockwise to increase pressure and counterclockwise to decrease pressure.

b.Always use the lowest pressure necessary to completely atomize the material.

operating the sprayer at higher

pressure than needed wastes material, causes early tip wear and reduces the life of the spray equipment.

c. If more coverage is needed, use a larger tip rather than increasing the pressure.

d. Check the spray tip. The tip size and angle determine the pattern width and flow rate.

6.Reduce clutch wear.

a.The first 50 feet of airless spray hose should be 3/8", the larger diameter works as a pulsation damper and saves unnecessary cycling of the clutch. A minimum of 100 feet of hose should be used.

b.Adjust the Engine Speed and Pump Pressure. First set the throttle lever to the maximum RPM setting (fully left). Trigger the gun onto a test paper to check the spray pattern and atomization. Adjust the Pressure Control Knob until you get a good pattern. Reduce RPM of engine to support pressure without overworking engines.

7.Clean tip if clogged. If tip is becoming worn, replace it. Worn tips waste paint, cause overspray, make cutting-in difficult, and decrease sprayer performance.

IMPORTANT: Always follow the Pressure Relief Procedure on page 3

before servicing unit.

Never hold your hand, body, fingers,

or hand in a rag in front of the spray tip when cleaning or checking it for a cleared tip. Always point the gun toward the front or into a waste container when checking to see if the tip is cleared or when using a self- cleaning tip.

a. Follow the Pressure Relief Procedure on page 3.

b. Clean the front of the tip frequently (with toothbrush only) during the day to keep material from building up and clogging the tip.

c. To clean and clear a tip if it clogs, refer to the separate instruction manual received with your gun and nozzle.

NOTE: When pausing during a paint job, keep tip clean by locking the gun and submerging the tip in a small bucket of paint thinner. This will help reduce buildup and drying of paint in tip, tip guard, and gun.

clean a clogged standard flat tip only after it has been removed from

the gun. Follow the Pressure Relief Procedure on page 3.

8.When shutting off the sprayer, follow this procedure.

a.Whenever you stop spraying, even for a short break, follow the Pressure Relief Procedure on page 3.

b.Clean the tip and gun as recommended by your separate gun instruction manual.

c.Flush the sprayer at the end of each work day if the material you are spraying is water-based, or if it could harden in the sprayer overnight. See "Flushing" on page 4. Use a compatible solvent to flush, then fill the pump and hoses with an oil based sovent such as mineral spirits.
