6.Disengage the gun safety latch and squeeze the gun trigger. Turn the

ON-OFFToggle Switch to the "ON" position (Figure 4) and turn Pressure Control Knob (Figure 3) clockwise to increase pressure just enough to start the pump.

7.Turn the Prime/PR Valve to the "CLOSED" position. This will allow solvent to be flushed through the pump, hoses and gun. Allow the unit to operate until clean solvent comes from the gun.

8.Release the trigger and engage the gun trigger lock.

9.If you are going to start spraying, place the suction tube into the supply container. Release the gun safety latch and trigger the gun into another empty, metal container, holding a metal part of the gun firmly against the pail and force the solvent from the pump and hose. Engage the gun safety latch until you are ready to spray.

10.If you are going to store the sprayer, remove the suction tube from the solvent pail, holding a metal part of the gun firmly against the pail and force the solvent from the pump and hose. Engage the gun safety latch. Refer to "Storage" Procedure on page 4.

11.Whenever you shut off the sprayer, follow the "PRESSURE RELIEF PROCEDURE" on page 3.

SETTING UP

Operation (Cont.)

SPRAY TECHNIQUE

Good Spray Gun Technique is at the core of any spray paint operation. Operator skill and efficiency is as important as good equipment and good paint. Good spray technique is a skill that can be developed by following these simple instructions.

If you are not familiar with spraying techniques, study this section of your manual and practice the proper technique on pieces of cardboard or a suitable surface.

Hold the spray gun 12 - 15 inches away from the work surface and keep it perpendicular (straight) to the surface. Move the spray gun parallel to the work and at a right angle to the surface. (See Figure 8).

Move the gun at a steady rate in order to apply a good coverage. The wet coat should be just under the thickness at which a run or sag will occur. Slow gun movement or gun held too close will result in an overly wet or thick wet or thick coat coverage that is likely to run or sag.

Do not wave the spray gun. This waving is called arching. Instead, hold the spray gun at a 12 to 15 inch

distance perpendicular from the work. (See Figure 9.)

The closer the spray gun is held to the work, the thicker the paint is deposited and the faster the gun must be moved to prevent sags and runs. Holding the gun too far from the work will cause excessive fog, overspray, and a thin and grainy coat.

It is important to "trigger" the gun after gun movement (arm movement) has started and release trigger (shut gun off) before gun movement ends. Gun movement is always longer than actual paint (spray) stroke. In that manner, even blending and uniform paint coat thickness is achieved over the entire surface. When the gun is in motion as the trigger is pulled, it deposits an even amount of paint.

Overlap the previous pass by half the width of the spray pattern. Aim at the bottom of the previous pass.

Adjust Pressure Control Knob so that paint is completely atomized from the spray gun. Insufficient pressure will result in “tailing.” Too much pressure will result in excess fog and overspray, excessive tip wear, and increased sprayer wear and tear.

Always use the lowest pressure possible to obtain desirable results. Test the

To cover “inside” and “outside” corners (on walls or other objects), aim the spray gun toward the center of the corner. The spray pattern is divided in half, and the edges of the spray pattern on both walls are the same.

Electrical System

ELECTRICAL BOARD CALIBRATION

NOTE: Anytime a sensor, pressure control assembly (board) or both are replaced, the following calibrations must be performed.

ZERO CALIBRATION

1.Place prime/pressure relief valve in the prime (open) position.

2.Set the pressure control knob to the minimum setting (CCW).

3.Remove the screws and lower the pressure control assembly.

4.Ensure the jumper is on the "P-ZR"terminal. Note: This jumper comes with a new pressure control

assembly (board) and is installed on the "P-ZR"terminals. If you are "Zero Calibrating" a pressure control assembly presently in the unit, remove jumper from single terminalP-ZRand place on both terminalsP-ZR.When Zero Calibration is complete, replace jumper on a single terminal ofP-ZR.

5.Turn machine "ON" and ensure it is not cycling.

6.If the yellow zero light on the electrical board is ON, use an insulated screwdriver to turn the "ZERO" trimpot counterclockwise until the light goes out. Then turn it clockwise until the light just comes back on. If so equipped, look at the LCD Display and if "0000" is showing the Zero Calibration is complete. If the display shows more than "0000", turn the Zero Trimpot CCW until "0000" is showing. If

"------"is showing, turn the zero trimpot CW until "0000" is displayed.

7.If the yellow light is OFF, turn the "Zero" trimpot clockwise, just until the light comes on and stop.

Confirm "0000" is displayed.

NOTE: If the yellow light remains constantly "ON" or "OFF" during this calibration, the sensor is defective and should be replaced.

8.IMPORTANT: When calibration is complete, move jumper from both"PZ-R"terminals to single terminal onP-ZR.

PRESSURE CALIBRATION

1.Complete the ZERO calibration, as per "ZERO CALIBRATION" prior to commencing this calibration.

2.Attach a 50', 1/4" airless hose, airless gun with 0.017 tip and a

5000 psi glycerin filled pressure gauge to the pump.

3.Place the suction tube into a bucket of Coro-chekand water.

4.Turn Prime/Pressure Relief Valve to the prime (open) position.

5.Turn Pressure Control Knob clockwise until machine starts to prime.

6.Place the Prime/Pressure Relief Valve in the pressure (closed) position.

7.While watching pressure gauge, slowly adjust the pressure trimpot (clockwise to increase and counterclockwise to decrease) until the maximum static pressure is 3000 psi, with the pressure control knob fully clockwise. Trigger the gun into pail several times to ensure pressure returns to 3000 psi.

LIQUID CRYSTAL DISPLAY (LCD) CALIBRATION

NOTE: Your unit may or may not be equipped with an LCD.

1.Complete the "ZERO CALIBRATION" and "PRESSURE CALIBRATION" procedures prior to starting this calibration.

2.Turn Pressure Control Knob up until system pressure is above 2500 psi (as indicated on glycerin filled pressure gauge) and the machine is not cycling.

3.Use an insulated screwdriver to adjust the Set trimpot. Turn trimpot counterclockwise until it clicks, and then adjust to match pressure against pressure gauge reading.

4.Move the pressure control knob to different settings and trigger the gun several times into pail. This will ensure that the LCD continues to match the pressure gauge reading.

PHASE LIMIT TRIMPOT CALIBRATION (formerly known as the Low Voltage or Master Voltage Calibration)

1.Attach a 50', 1/4" airless hose, airless gun with .017 tip and a 5000 psi glycerin filled pressure gauge to the pump.

2.Place the suction tube into a bucket of Pump Conditioner and water.

3.Turn pump ON and turn up Pressure Control until the machine starts to prime.

4.Place the Prime/Pressure Relief Valve in the pressure (closed) position.

5.Pressurize pump to 600 psi.

6.Trigger the gun several times noting the deadband (the amount of pressure drop before the pump rebuilds to set pressure).

7.If deadband is greater than 100 psi, adjust the low pressure voltage trimpot so that the deadband is less than 100 psi and the pressure increase after the gun trigger is released is less than 200 psi.

These pressures are guidelines and may vary slightly from pump to pump.

8.Reattach Pressure Control Assembly being careful not to pinch wires.

NOTE: The331-315-99Pressure Control Assembly has a reddish brown terminal labelled “Inhibit Switch.” At all times there should be a jumper on the two left terminals, which are the closest to the “S2” connection. Also on the Revision E is a terminal labelled “ONSL.” This terminal should never have a jumper on it.
