Introduction
These spray guns are designed for use in a High Volume/Low Pressure
(HVLP) painting system.
With an HVLP system, the highest quality professional nish can be
achieved with little preparation or setup time. HVLP systems are
not intended to replace airless systems. Instead, they are meant to
compliment airless by improving the nal nish on the substrate,
minimizing waste, and reducing labor time. In addition to enhancing
protability, HVLP systems are compliant with the most stringent
transfer eciency requirements.
The HVLP spray guns described in this manual include the turbine
cup gun and the turbine top feed gun. Please review all the
information contained in this manual before operating an HVLP
system.

4. Remove the gun body O-ring from the gun body. You may
need to use a needle-nose pliers or some other long, thin
object to remove it from the gun body.
Replacing the Check Valve Retainer, Valve Seal and
Air Tube
The check valve is a one-way valve designed to allow air into the
cup, pressurizing the cup’s contents. Because it is a one-way valve, it
prevents paint from seeping up the air tube into the air passages of
the gun. It also eliminates any delay in material ow when the gun is
triggered by maintaining pressure in the cup.
The check valve rotates open easily for cleaning. It contains a valve
seal that can be removed and cleaned with soap and water for
waterborne materials or a compatible solvent for other materials. To
replace the the valve seal and/or the air tube:
1. Unscrew the check valve retainer by turning it
counterclockwise.
2. Pull the valve seal out of the gun head. Clean or replace the
valve seal.
NOTE: The check valve area inside the gun head should
also be cleaned of any accumulated spray material.
DO NOT use anything metal or abrasive to clean the
check valve area as it will scratch the metal surface,
and the valve seal will not seal properly.
3. Reinstall the valve seal. Insert the stem of the valve seal into
the hole of the gun head.

5. To replace the air tube, pull it from the nipples on both the
gun head and the cup assembly. Replace with a new tube.
The cup is designed for a maximum working pressure
of 6 PSI (0.41 bar). Pressures higher than 6 psi can
result in cup leakage, damage to the equipment, and/
or potential injury to the user.
The top feed HVLP spray gun is designed for use in special
applications such as spraying in conned areas. The position of
the cup gives the top feed gun the ability to spray downward and
overhead. When spraying with the top feed gun, remember the
following tips for the best results. Keep the cup pressurized at all
times when spraying. Attempting to gravity feed the material will
slow or stop the ow of material at the nozzle.
NOTE: It is recommended that the gun hook be removed
whenever using the top feed cup assembly.
To set up the spray gun for top feed delivery:
1. Loosen the retaining nut using a wrench and remove the one
quart cup assembly.
2. Pull the air tube o of the air tube tting on the spray gun.
3. Separate the gun head from the gun rear (see instructions
on page 3). Reassemble gun head upside-down so uid inlet
tting on gun head points upward to accept the top feed cup
assembly.
4. Remove the gun hook and thread the retaining nut of the topfeed cup assembly onto the uid inlet of the gun head. Rotate
the stand away from the cup and set the gun assembly on a
level surface.
5. Using an adjustable wrench, secure the retaining nut, making
sure the gun/cup assembly stays in a level position. The cup
should end up in a vertical position when supported by the
stand.
6. Connect the air tube to the air tube tting on the spray gun.
IMPORTANT: The gun, when converted to top-feed, will not
stand on its own. Make sure to use the stand when filling. Do not
lay the gun on its side when it is filled with material. Do not hang
the gun by its hook when lled with material.
Converting the gun from Non-Bleeder to
Bleeder
Your HVLP spray gun can be converted from a non-bleeder to a
bleeder setup. Bleeder setup provides more atomizing power for
higher viscosity materials, such as latex and enamels. Bleeder setup
can make it easier to spray in conned spaces, such as inside cabinets,
because the air hose is moved to the back of the gun.
To convert a spray gun to bleeder setup:
1. Remove the air ow adjustment knob from the rear of the gun
using a wrench.
2. Remove the air inlet tting from the bottom of the gun handle
using a wrench.
3. Thread the air inlet tting into the air ow adjustment knob
location at the rear of the gun. Secure the tting in place.

5. Attach the air hose to the relocated air inlet tting.
NOTE: In bleeder setup, the removal of the air ow
adjustment knob causes the air supply to be on at all
times when the air hose is attached to the gun.

Choosing a Projector Set
Fluid nozzle
Air cap
Your HVLP spray gun should be tted with the proper projector set
for the type of work you will be performing. A projector set consists
of a needle assembly, a uid nozzle, and an air cap.
Needle assembly
You should choose a projector set based on two things: the type of
material to be sprayed and the nish desired.
The chart on the following page should help you to make the right
choice.

Before spraying, the material being used must be thinned with an appropriate solvent and the proper projector set must be installed. It is
always best to follow the material manufacturers recommendations and thinning procedures.
There are two simple methods of measuring the proper thickness of a material:
1. Dip a paint stick into the material and remove it, watching carefully as the material runs o. When the material begins to form drops, the
drops should fall about 1 second apart.
2. Use a viscosity cup (P/N 0153165). Dip the cup into the material and remove it. Use a watch or clock to time how long the material drains
from the cup in a continuous stream. Once the continuous stream breaks, stop timing and refer to the table below. Add the appropriate
solvent and continue testing until the proper thickness is reached for the type of material you are using.
