SPRAYING TROUBLESHOOTING

The following is a short list of minor difficulties you might encounter while spraying. If any of these occur, it will reduce the flow of paint, making your spray pattern poor, or paint will fail to spray from the gun.

Clogged spray tip

Clogged gun filter

Clogged suction set screen

Follow the guidelines on this page to correct any one of these problems.

UNCLOGGING THE SPRAY TIP

WARNING

Do not attempt to unclog or clean the tip with your finger.

CAUTION

Do not use a needle or other sharp pointed instrument to clean the tip. The hard tungsten carbide can chip.

If the spray pattern becomes distorted or stops completely while the gun is triggered, follow these steps:

1. Release the trigger and lock the gun off.

GX-06/07

GX-08/10

2.Rotate the reversible tip arrow 180° so that the point of the arrow is toward the rear of the gun (CLEAN position).

Under pressure, the spray tip may be very difficult to turn. Turn the PRIME/SPRAY knob to PRIME and trigger the gun. This will relieve pressure and the tip will turn more easily.

3.Turn the PRIME/SPRAY knob to SPRAY.

4. Unlock the gun and squeeze

the trigger, pointing the gun at a scrap piece of wood or cardboard. This allows pressure in the spray hose to blow out the obstruction. When the nozzle is clean,

paint will come out in a straight, high pressure stream.

If paint still will not spray from the spray tip, follow the other steps on the next column.

5. Release the trigger and lock the gun off.

6. Reverse the tip so the arrow points forward again (SPRAY position).

7. Unlock the gun and resume spraying.

CLEANING THE SPRAY GUN FILTER

This filter must be cleaned every time

Filter top

you use your sprayer.

 

When using thicker paints, the filter

 

might need to be cleaned more often.

 

1.

Perform Pressure Relief

 

 

Procedure (page 6).

 

2a.

If you have a model GX-06/07

 

 

spray gun, unscrew the fitting from

Pin hole

 

the bottom of the spray gun using

 

 

an adjustable wrench, making sure

 

 

not to lose the spring.

3.Remove the filter from the spray gun housing and clean with the appropriate cleaning solution (warm, soapy water for latex paints, mineral spirits for oil-based materials).

4.Inspect the filter for holes (see Hole picture, above). Replace if holes are found.

CAUTION

NEVER POKE THE FILTER WITH A SHARP INSTRUMENT!

5.Replace the cleaned filter, tapered end first, into the gun housing.

The tapered end of the filter must be loaded properly into the gun. Improper assembly will result in a plugged tip or no flow from the gun.

6a. For the GX-06/07,replace the spring and the fitting. Tighten with an adjustable wrench.

6b. For the GX-08/10,replace the housing and snap the trigger guard back into the housing.

CLEANING THE SUCTION SET SCREEN

The screen at the bottom of the suction set may also need cleaning. Check it every time you change paint buckets.

1. Remove the screen by pulling it out of the retainer with a plier.

2. Clean the screen with the appropriate cleaning solution (warm, soapy water for latex paints, mineral spirits for oil- based paints).

If after having completed all of the steps on this page you are still experiencing problems spraying, refer to the TROUBLESHOOTING guide (page 15).
