Operation
3.3 Preparing a new sprayer
If this unit is new, it is shipped with test fluid in the fluid section
to prevent corrosion during shipment and storage. This fluid
must be thoroughly cleaned out of the system with mineral spirits
before you begin spraying.
Attention
Always keep the trigger lock on the spray gun in
the locked position while preparing the system.
1. Place the siphon tube into a container of mineral spirits.
2. Place the return hose into a metal waste container.
3. Turn the pressure control knob fully counterclockwise to
its lowest pressure setting (fig 5, 2).

test fluid out through the return hose and into the waste
container.

3.4 Preparing to Paint
Before painting, it is important to make sure that the fluid in the
system is compatible with the paint that is going to be used.

Incompatible fluids and paint may cause the
valves to become stuck closed, which would
require disassembly and cleaning of the sprayer’s
fluid section.
Attention
Always keep the trigger lock on the spray gun in
the locked position while preparing the system.
1. Place the siphon tube into a container of the appropriate
solvent for the material being sprayed.
i
If you are spraying a water-based latex, flush with
warm, clean water. If you are using any other
material, check with the material manufacturer for
a compatible solvent.
