Check Fluid Viscosity
To check fluid viscosity you will need:
a viscosity cup
a stopwatch.
1. Completely submerge the viscosity cup in the fluid.
Lift the cup out quickly, starting the stopwatch as
soon as the cup is completely removed.
2. Watch the stream of fluid coming from the bottom of
the cup. As soon as there is a break in the stream,
shut off the stopwatch.
3. Record the fluid type, elapsed time, and size of the
viscosity cup.
4. If the viscosity is too high or too low, contact the
material supplier. Adjust as necessary.
Prepare to Paint
1. Position air cap.
2. Fully open fan air adjustment valve.
3. Fully open fluid adjustment valve.
4. Fully open atomizing air restrictor valve.
5. Check that ES ON/OFF switch is OFF (O).
6. Start pump. Adjust fluid regulator until stream from
gun travels 8-12 in. (200-300 mm) before falling off.
Typically, if fluid pressure is below 5 psi (.04 MPa,
0.4 bar) or above 20 psi (0.14 MPa, 1.4 bar), a
change of nozzle size is recommended.
