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 material, making your spray pattern poor, or material will fail to spray from the gun.

•Clogged spray tip

•Clogged gun filter

•Clogged inlet filter

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

UNCLOGGING THE SPRAY GUN FILTER

This filter must be cleaned every time you use your sprayer. When using thicker paints, the filter might need to be cleaned more often.

1.Perform Pressure Relief Procedure (page 5).

2.Unclip the trigger guard from the filter housing by pulling outward from the filter housing. Unscrew the housing.

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.Turn the pump off, and release the trigger and lock the gun off.

O

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 high pressure stream.

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

5.Release the trigger and lock the gun off.

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

7.Unlock the gun and resume

spraying.

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).

When cleaning filter, look for sediments in the spraying material you are using. Refer to Paint Straining, (page 5).

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.

6.Replace the housing and spring and snap the trigger guard back into the housing.

UNCLOGGING THE INLET FILTER

1.Perform Pressure Relief Procedure, (page 5).

2.Empty the hopper of all spraying material (see Emptying the Hopper, page 5).

3. Remove the inlet filter from the hopper. You may need to use a screwdriver to pry the filter loose.

4.	Clean the inlet filter using
	the appropriate cleaning
	solution (warm, soapy water	Inlet
	with latex paints, mineral
		filter
	spirits with oil-based paints
	or stains).
5.	Replace filter.

If after having completed all of the steps on this page you are still experiencing problems spraying, refer to the TROUBLESHOOTING page (page 12).
