Warning Symbol
WARNING
This symbol alerts you to the possibility of serious
injury or death if you do not follow instructions.
Caution Symbol
CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow instruc-
tions.
You will need:
Cleaning fluids: a compatible solvent; water–based paint also requires soap and water.
Suggested proper clothing:
•Safety glasses •Sturdy boots or shoes
•Respirator •Gloves
TOXIC FLUID HAZARD: Hazardous fluid or toxic
fumes can cause serious injury or death if
splashed in eyes or on skin, inhaled, or swallowed.
DKnow specific hazards of fluid you are
using and take protective measures as
recommended by the fluid and solvent manufacturer.
Equipment Misuse Hazard: Equipment misuse
can cause the equipment to rupture or malfunction
and result in serious injury.
DBefore operating equipment, read all instruction
manuals, tags, and labels.
DCheck equipment daily. Repair or replace worn
or damaged parts immediately.
DDo not exceed maximum working pressure (MWPR) of the lowest–rated
system component
DUse fluids and solvents that are compatible with the equipment
wetted parts. See Specifications on page for this information.
DWear hearing protection when operating this equipment.
DDo not “blow back”fluid; this is not an air spray system
DFollow Pressure Relief before cleaning, checking or servicing the
equipment.
Fire and explosion hazard: Solvent and paint
fumes can ignite or explode.
DSprayers generate sparks. Keep sprayer at least
20 feet (6 m) from explosive vapors.
DUse in an extremely well ventilated area.
DEliminate all ignition sources; such as pilot lights,
cigarettes and static arcs from plastic drop cloths.
Do not plug or unplug power cords or turn lights
on or off in spray area.
DGround Sprayer, object being sprayed, paint and
solvent pails.
DDo not use 1,1,1-trichloroethane, methylene chlo-
ride, other halogenated hydrocarbon solvents or
fluids containing such solvents in pressurized alu-
minum equipment. Such use could result in a
chemical reaction, with the possibility of explosion.

Installing the Fluid Set
Trigger the gun whenever you tighten or remove the nozzle. This keeps the needle seat away from
the nozzle seating surface and prevents the seat from being scratched.
CAUTION
For Cup Guns
Follow these
instructions whenever
you stop spraying.
1. Turn off air supply to the pot.

For Pressure Feed Guns
2. Open pressure relief (A) on
pot until pressure is completely
relieved. Close relief.

Follow these
instructions whenever
you stop spraying.

1. Use your hand to loosen and remove the air cap retaining ring
and air cap housing.
2. Test spray pattern and atomization while holding gun about 6
to inches (150 to 200 mm) from test piece.
3. While triggering the gun, use your hand to loosen and remove the nozzle.
4. Use your hand to loosen and remove the fluid knob assembly and
compression ring from the back of the gun and remove the old needle.
5. Insert the needle assembly in the back of the gun. Reassemble nozzle, air cap housing and air cap re-
taining ring. Hand tighten.
Note: Nozzle should always have an o–ring (A).

6. Connect air hose to gun and turbine.
7. For cup gun, turn fluid control out until trigger movement is not restricted.
Caution: Turning knob too far will remove it.
Setup
8. Reduce and test catalyze all paint to manufacturer’s specifications.
SIf no reduction instructions are given, mix the fluid thoroughly, then gradually mix in reducer. To check
the consistency of the fluid. Remove the stir stick from the thinned paint. When the paint streaming off
the stick breaks into droplets, the first few drops should be one second apart.
STo compensate for faster drying time of turbine systems, use a reducer one step slower than used for
conventional air spray systems.
9. Remove cup. Fill 3/4 full. DO NOT OVERFILL. Reattach and latch cup.
For remote pressure pot, hold gun parallel to floor and adjust fluid pressure
to an 8 to 10 inch (203 to 254 mm) fluid stream.
NOTE: Heavier fluids or longer fluid hoses require greater pressures.

10. Plug turbine power cord into a grounded outlet.
SPRAY
11. Open air control valve.
12. Turn turbine on. Wait several minutes prior
to spraying to allow warm–up time.
13. Turn air cap to obtain desired direction.

14. Lock air cap with retaining ring.
15. Select spray pattern by adjusting the fluid knob
and pattern selection knob. The air control ad-
justs the TOTAL air to the pattern and gun.

17. To control over–spray, reduce air flow or reduce fluid volume.
Note: If fluid is not atomizing properly, fluid may need to be thinned further, or a different
tip size may be used.
Swivel Tube Adjustment
The adjustable swivel tube allows the HVLP–Turbine Gun to be held in any position why spraying. To adjust the
position of the tube in the cup:
1. Loosen the nut (A) with a wrench (42).
2. Rotate the cup to the desired spray position.
3. Retighten the nut (A) with a wrench (42).
