Mix Paint, Adjust Pressure and Spray
Prepare paint as instructed by manufacturer. Also see
instruction manual 306-997.
Put paint suction tube into pail of paint. Do not install
spray tip yet. Squeeze gun trigger, turn the unit on, and
let it run until all air is forced out of system. To avoid in-
troducing more air into the fluid line, always add paint
to original pail rather than changing pails.
NOTE: If paint is thick and hard to prime, first
remove strainer from suction tube, then
prime unit with water or compatible solvent.
When primed, turn unit OFF, plug immersed
end of suction tube with one finger and
transfer it into pail of thick paint. This keeps
air out of pump for more positive priming.
Replace strainer.

Unplug unit, relieve pressure acording to Pressure Relief
Procedure on page 3, and install Reverse-A-Clean III
spray housing with tip installed (see instruction manual
307-321) on gun. Adjust spray pressure to the lowest
pressure needed for satisfactory operation and spray a
test area to check spray pattern. Refer to instruction
manual 306-997 for spraying technique. For further in-
formation on tip selection, see instruction manual

Cleaning A Clogged Tip
If spray tip clogs while spraying, release spray
gun trigger and turn Reverse-A-Clean handle 180”.
Disengage safety and trigger gun. Fluid pressure should
force obstruction from spray tip. Release trigger,

trigger safety,
return handle to original position
and resume spraying.
Always wrap hose around hose brackets when storing
unit, even if only overnight, to help protect hose from
damage. Suction hose and tube can be routed around
rear bracket and tube end slipped under front bracket.
Don’t store unit with water in it. Even for overnight
storage you should fill the unit with mineral spirits. This
prevents rust and greatly extends the life of the unit.
If fluid pressure fails to clear tip, see Reverse-A-Clean
