Check Fluid Resistivity

Fire, Explosion, and Electric Shock Hazard
Check the fluid resistivity in a non-hazardous area
only. Resistance Meter 722886 and Probe 722860 are
not approved for use in a hazardous area.
Failure to follow this warning could cause fire,
explosion, or electric shock and result in serious injury
and property damage.
Graco Part No. 722886 Resistance Meter and 722860
Probe are available as accessories to check that the
resistivity of the fluid being sprayed meets the require-
ments of an electrostatic air spray system.
Follow the instructions included with the meter and
probe. If the material is above 1 megohm-cm, then a Pro
Xs Auto HC gun may be a better option. The Pro Xs WB
gun is intended to spray very conductive waterborne
materials and other materials less than 1 megohm-cm.

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.

Install the Fabric Cover

1. Install a fabric cover (XX) over the front of the gun
and slide it back to cover the exposed tubing and
hoses at the back of the manifold. See F
2. Route the exhaust tube (YY) outside the cover. This
enables you to monitor the exhaust tube for the
presence of any paint or solvent. See Check for
Fluid Leakage on page 21. Strap down the exhaust
tube to prevent it from moving around.
