IMPORTANT: Before using this equip-
ment, read all safety precautions
on page 2 and instructions. Keep for
future use.
GUN DESCRIPTION –
110268 (
FUN-600G)
The FUN-600G is a light weight, general
purpose compliant high volume low
pressure gravity feed spray gun. It is
designed to apply a wide variety of com-
mon coating materials.
IMPORTANT: This gun may be used with
most common coating and finishing
materials. It is designed for use with mildly
corrosive and non-abrasive materials.
If used with other high corrosive or
abrasive materials, it must be expected
that frequent and thorough cleaning will
be required and the necessity for replace-
ment of parts will be increased.
Note
This gun includes 303 series
stainless steel fluid tip and
needle. Guns may be used with
chlorinated solvent materials
only if the attached gravity cup
is Delrin or Nylon.
Do not use
aluminum cups with chlorinated
solvent materials.
This gun was manufactured to provide
maximum transfer efficiency by limiting air
cap pressure to 10 psi (complies with rules
issued by SCAQMD and other air quality
authorities).
This gun will produce approximately 10 psi
cap pressure at 18 psi gun inlet pressure, as
measured at the gun inlet. An air cap test kit
(see Accessories) should be used to insure
10 psi cap pressure is not exceeded.
The No. V (HVLP) air cap requires an
air supply of 8 SCFM and an air pressure of
18 psi when measured at the gun inlet
and with the trigger pulled.
CUP DESCRIPTION –
192298 (
KGP-4)
This gun is supplied with a 400 ml cup. The
cup is constructed from durable
Acetal to provide trouble-free operation.
The cup insert is nickel plated brass. The
cup has a stand built into the bottom to prop
up the gun.
INSTALLATION
For maximum transfer efficiency,
do not
use more pressure than is necessary to
atomize the material being applied.
Attach the gravity feed cup to the material
inlet by hand-tightening the wing nut.
Note
Protective coating and rust inhibi-
tors have been used to keep the
gun in good condition prior to
shipment. Before using the gun,
flush it with solvents so that these
materials will be removed from
fluid passages.
Connect the gun to a clean, moisture and oil
free air supply using a hose size of at least
5/16" I.D.
hose. Do not use 1/4" I.D. hose.
(25' x 1/4" hose at 18 CFM has a pressure
loss of 25 psi. 25' x 5/16" hose at 18 CFM has
a pressure loss of 8 psi.)
Note
Depending on hose length, larger
I.D. hose may be required. Install
an HAV-501 air gauge at the gun
handle and air cap test kit over tip.
When gun is triggered on, adjust
regulated pressure to desired
setting to provide a maximum of
10 psi at the air cap.
Do not use
more pressure than is necessary
to atomize the material being ap-
plied.
Excess pressure will create
additional overspray and reduce
transfer efficiency.
Note
If quick connects are required, use
only high flow quick connects ap-
proved for HVLP use, such as
DeVilbiss HC-4419 and HC-4719.
Other types will not flow enough
air for proper gun operation.
Note
If an air adjusting valve is used
at the gun inlet, use DeVilbiss
Model HAV-500 or HAV-501.
Some competitive adjusting
valves have significant pressure
drop that can adversely affect
spray performance. Models
HAV-500 and HAV-501 have
minimal pressure drop, which is
important for HVLP spraying.

OPERATION
Mix, prepare and strain the material to
be sprayed according to the paint
maufacturer's instructions.
Strain material through a 60 or 90 mesh
screen.
Fill the cup with paint to the full mark
(400 ml).
Do not overfill.
Screw the plastic lid on the top of the cup.
Make sure that the cup lid vent hole is
clear.
Open the spreader adjustment valve (8)
(Fan) by turning the valve stem counter-
clockwise.
Close the fluid needle adjusting knob (15)
by turning clockwise.
Turn on air supply and set gun inlet
pressure to lowest recommended
pressure for material being sprayed. Best
atomization will occur with 10 psig air cap
pressure. However, some materials can be
sprayed at lower pressures, improving
transfer efficiency.
Spray a test area. Turn the fluid needle
adjusting knob (15) counterclockwise until
a full coat is obtained.
If the finish is too sandy and dry, the
material flow may be too low for the
atomization air pressure being used.
Turn the fluid needle adjusting knob (15)
counterclockwise to increase fluid flow.
If the finish sags, there is too much material
flowing for the atomization air pressure
being used. Turn the fluid needle adjusting
knob (15) clockwise to decrease fluid flow.
Pattern width can be altered by turning
spreader adjustment valve (8), either
clockwise to decrease the width or counter-
clockwise to increase the width.
Adjust inlet air pressure to provide a uni-
form dispersion of atomized paint through-
out the pattern. Keep air pressure as low as
possible to minimize bounce-back and
overspray. Excessive pressure will result in
split spray patterns. Inadequate pressures
will cause heavy centered patterns and poor
atomization.
