Viscosity - Central Pneumatic Professional 94572 Assembly And Operating Instructions Manual

IMPORTANT: The Spray Gun must be cleaned immediately after use.
Improper cleaning is a common reason for the Spray Gun not to work.
Fan direction and Pattern Adjustment (continued)
3. Turn the Fluid Control Knob (13A) clockwise until it is fully closed. See FIG 1 on page 6.
4. After setting up a piece of scrap material, squeeze the Trigger (23A) all the way in short
bursts while turning the Fluid Control Knob (13A) counterclockwise and observe the spray
patterns until you see the pattern you want. Also, look at the pattern for consistency. Too
much air may cause the spray to come out too fine. Reduce the air pressure or allow
more material to come out by opening the Fluid Control Knob (13A). If the spray ap-
pears too thick (you see globs of paint), close down the Fluid Control Knob (13A) slowly,
checking the mixture after each adjustment.
See FIGURE 5 below.
FIGURE 5
Viscosity is the technical term used to indicate the liquidity (thickness or thinness) of the mate-
rial to be sprayed. Viscosity is measured in the number of seconds required for the material to
pass through a Viscosimeter. These sprayers can spray materials with a viscosity ranging from
10, to a maximum of 60. Material with a higher viscosity can be used only with water-soluble
products (outdoor and indoor wall applications). Use high quality products. The following table
gives some guidelines on thinning.
To test the viscosity of a material:
1. Place your finger over a Viscosimeter (not supplied) output hole.
2. Fill the Viscosimeter to the top with the material to be sprayed.
3. While holding the Viscosimeter over the material source can, let go of the output hole
and count the number of seconds it takes for it to empty completely. The number of
seconds is the viscosity rating.
