CUHF-
High Volume Low Pressure
Manual Spray Gun
OPERATING INSTRUCTIONS & REPLACEMENT PARTS
DESCRIPTION:
CUHF- Manual Spray Gun is for use with Light to Heavy
consistency materials. Best spray results are achieved
using pressure fluid feed, although gravity and siphon
cups can also be used. These models require 3 to 10
C.F.M. @ 20 to 50 P.S.I. air pressure depending on size
of Spray Head selected and material being sprayed.
SPECIAL NOTE: CFH- Spray Head with U-3609 Air
Inlet Tube required for High Volume Low Pressure
operation.
AIR CONNECTIONS:
This model has 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.
Warning: Secure air hose so it doesn’t injure
anyone during purging.
2. Connect air hose to U-3609 Air Inlet Tube on the
CUHF- Bottom Air Inlet Model.
FLUID CONNECTIONS:
This model has 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 Fluid Feed operation requires that you
attach one end of fluid hose to approved ASME
pressure tank and the other end to the fluid inlet on
the Fluid Body Assembly (Recommended Method).
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.
SPRAY HEAD:
1. CFH- Spray Head (Fan Pattern) (HIGH VOLUME
LOW PRESSURE) has maximum head pressure of
10 P.S.I. when controlled line pressure does not
exceed 50 P.S.I. and requires the use of a U-3609
Inlet Tube.
OPERATION:
Adjust 200-17 Fluid Knob on CUHF- (Bottom Air Inlet)
Models to regulate the flow of material through the Spray
Gun.
Grip Spray Gun as you would a pistol, place two fingers
on the trigger. The first one quarter inch of 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 8 to 10 inches from the surface to achieve fan
patterns from 3 to 10 inches in width. For narrow fan
patterns, use short trigger pull and hold Spray Gun closer
to the surface. To get wider fan pattern, 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.
