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.

4. Fully open atomizing air restrictor valve.

5. Check that ES ON/OFF switch is OFF (O).

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.

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.
