8. Remove the fluid container and suction set.
9. Clean all parts thoroughly with the brush provided using a
solution appropriate to the type of material you sprayed.
CAUTION
Make sure to completely remove all material from the inside
of the piston chamber by scrubbing with the brush. Even a
small amount of material can dry like glue and keep the
piston from moving, causing damage to the sprayer.
Make sure to keep the vent hole on the pump housing clean
and unblocked or a vacuum can build up in the container
and cause damage to the sprayer. A toothpick or
straightened paper clip can be used to clean it.

pump housing is pushed far enough into the sprayer and
the locking nut is screwed on tightly.

7. Place the spray tip onto the pump housing and turn it
clockwise until it is tightened securely.

LUBRICATING THE SPRAYER

NOTE: Lubricating your sprayer prior to storage is
important to prolong the life of the pump
housing components.
1. Turn the sprayer upside-down while the fluid container is
removed.
2. Pour a small amount of standard houshold oil into both the
intake and return openings on the pump housing.

3. Plug in the sprayer.
4. Squeeze the trigger of the sprayer for 2 to 3 seconds while
sprayer is still inverted as shown above. This works the
household oil onto the piston and swirl valve. The oil
protects the sprayer by keeping any extra material from
drying and seizing the piston.
5. Replace the suction set and thread the fluid container onto
the sprayer.
