DESCRIPTION:
BUB- and BUT- Manual Spray Guns (“T” means thumb

action) are for use with Light to Medium consistency
materials. These models require 2 to 14 C.F.M. @ 30 to
40 P.S.I. air pressure depending on size of Multiplehead
selected.

AIR CONNECTIONS:

These models have 1/4'' N.P.T. Air Inlet.

1. Open air control valve and blow out Air Hose to
remove any foreign particles that may be in airline.
Secure air hose so it doesn’t injure anyone during
purging.

2. Connect air hose to the U-807 Air Inlet Tube on
BUB- Bottom Air Inlet Model. Connect air hose to
U-49A Valve Casing on BUT- Thumb Action Spray
Gun.

FLUID CONNECTIONS:

These models have 3/8'' N.P.T. Fluid Inlet.

1. For Siphon Feed, attach siphon feed cup to bottom
inlet of Fluid Body Assembly.

2. For Gravity Feed, loosen U-58 Nut and then turn
fluid inlet of Fluid Body Assembly to top of Spray
Gun and connect Gravity Feed Cup. Tighten U-58
Nut.

3. Pressure Tank operation requires that you attach
one end of fluid hose to pressure tank and the
other end to the fluid inlet on the Fluid Body
Assembly.

MATERIAL:

1. Mixture should be to the consistency
recommended by the manufacturer.

2. Strain all materials through a cloth or fine wire
mesh prior to using to insure all foreign particles
have been removed.

OPERATION:

1. Adjust 200-17 Fluid Knob on BUB- (Bottom air
inlet) Model to regulate the flow of material through
the Spray Gun.

2. To control fluid on the BUT- Spray Gun, adjust the
U-1816 Adjusting Screw on the trigger.

Grip Spray Gun as you would a pistol, place two fingers on
the trigger. The first one quarter inch pull releases air only
and is used for cleaning by dusting surfaces before
painting. Continued pull on the trigger retracts the Fluid
Needle and allows maximum fluid passage.

Begin Painting by applying as light a coat as possible. Take
long strokes from side to side releasing the trigger at the end
of each stroke. For average work, hold head of Spray Gun
6 to 8 inches from the surface; for narrow lines, use short
trigger pull and hold Spray Gun closer to the surface. To get
wider spray patterns, draw Spray Gun away from surface
gradually while trigger is pulled back until desired width of
pattern is obtained. Practice before spraying on your project
is always advisable.

CARE AND CLEANING:

Flush clean solvent through the fluid passages of the Spray
Gun and wipe off the outside. Never leave the entire Spray
Gun immersed in solvent or the leather packings will dry out.
Dirty Aircaps and Tips should be cleaned out by soaking in
solvent and then blown clean with air. Never use wire
objects to ream out the holes in aircaps or tips as this will
damage these items. Always follow safety instructions on
cleaning solvents being used and remember to keep your
containers closed in a safe location.
