SPRAYING

Continued from page 17

Cleaning The Spray Gun Filter

The spray gun includes a filter to catch particles before

they reach the spray tip. If this filter becomes clogged or

obstructed it will reduce the flow of paint, changing the

spray pattern and possibly damaging the filter.

This filter must be cleaned at least daily and perhaps

even every four hours with certain types of latex

materials.

If the filter is not cleaned at the proper time, it will plug from

the top down. When there is about 1 inch of filter that isn't

plugged, the heavy flow of paint will blow pin holes in the

filter. See Figure 30. This in turn will allow unwanted

particles to get into the spray tip, causing spray tip to clog.

Pin Hole

Figure 30 - Gun Filter Cleaning.

To clean the filter during the painting process:

1. Turn spray PRESSURE CONTROL KNOB to mini-

mum setting and turn PRIMING KNOB to PRIME A .

This will bleed off the pressure in the paint hose and

filter. Trigger gun to be sure pressure is gone. Refer

to Pressure Relief Procedure.

2. Remove spray gun from hose using two adjustable

wrenches. See Figure 10

3. Unscrew filter housing, using adjustable wrench on

the nut at the bottom of the housing.

4. Remove filter being sure not to lose the spring and

sealing washer which is located in the bottom of the

filter housing.

5. Clean filter thoroughly (or put in a new filter). To clean

the filter, swish it in water or the type of solvent

appropriate to the paint you are using. If this isn’t

sufficient, use a natural or nylon bristle brush dipped

in the appropriate solvent or water. Do not use a wire

brush or any sharp instrument.

6. Insert the top of the filter (Figure 30) into the gun body

fitting under the tip of the spray gun. See Figure 31.

Suction Set Screen

The screen at the bottom of the suction set may also need

cleaning periodically. Check it every time you change

paint buckets. Remove screen by pulling it out of the

retainer with a pliers. Clean the screen with water or

solvent and a soft-bristle brush, if needed.

7. Replace the spring and sealing washer into the base

of the filter housing.

8. Slide the filter housing over the filter and tighten it

securely to the gun, using a wrench.

9. Reattach the hose, tightening it securely with two

wrenches.

10. Turn PRIMING KNOB to SPRAY B , (Figure 10)

increase pressure to its previous setting and resume

spraying.
