SPRAY TIP PLUGGING
The spray tip can be plugged by foreign matter and “skin”
in the paint. Excessively large paint pigments can also plug
the tip. If the tip becomes plugged while spraying, proceed
as follows:
1. Lock spray gun trigger OFF so that the spray gun can't
spray.
2. Turn sprayer ON/OFF switch OFF.
3. Reduce pressure by turning the pressure control knob
counterclockwise. Turn priming valve knob to to
bleed pressurized paint in paint hose and spray gun
back into paint container.
4. Remove tip guard assembly with spray tip and sealing
washer from spray gun as shown in Figure 3, page 10.
5. Remove spray tip and sealing washer from tip guard
assembly.
6. Soak tip guard assembly, spray tip, and sealing washer
in solvent. Then clean them with a stiff brush. A tooth-
pick, wood chip, or sharpened matchstick can be used
to clean the spray tip hole.

SPRAY GUN FILTER CLEANING AND
CHANGING
Clean or change the spray gun filter at least once per
painting day, some types of latex paint may require filter
cleaning or changing more often.
The filter is best cleaned with a brush dipped in appropriate
solvent. Never poke the filter with a sharp instrument.
If the filter is not cleaned or changed at the proper time, it
will plug from the top down. When there is about 1 inch or
so of the filter left that isn’t plugged, the heavy flow of paint
will blow pinholes in the filter. An example of this is shown
in Figure 12.
Never clean the spray tip hole with a wire or metal
object as these items will cause damage.
CAUTION
7. Reassemble the spray tip, sealing washer, and tip guard
assembly onto the spray gun the same way you did
when you assembled the unit. See “ASSEMBLY OF
SPRAY GUN”, page 10.
To remove and replace the filter, proceed as follows:
1. Lock spray gun trigger OFF.
2. Turn sprayer ON-OFF switch OFF.
3. Reduce pressure by turning the pressure control knob
counterclockwise. Turn priming knob to . This will
drain the pressurized paint in the paint hose and spray
gun back into the paint container.
4. Remove the paint hose from the spray gun as shown in
Figure 13.
5. Remove the handle from the spray gun.
6. Remove the old filter. Use a new filter, or clean the old
filter.
