General Information
System HVLP Turbine Sprayers
The System 2500, 3800, and 4900 Sprayer,
System ProCart, and HVLP–Turbine Gun can spray
most coatings or finishes currently being used for
automotive refinish, industrial, aerospace, marine,
wood, plastic, and architectural applications.
To produce high-quality paint finishes, the spray gun
typically utilizes inbound air pressure of 5 psi (0.3 bar,
34 kPa) for System 2500; 6 psi (0.4 bar, 41 kPa) for
System 3800; and 8 psi (0.5 bar, 55 kPa) for
System 4900. A cone of air, produced by the gun,
carries and directs the paint from the gun to the
surface, minimizing overspray and increasing transfer
efficiency. This enables painters to comply with new
clean air laws that are designed to reduce VOC
(volatile organic compounds) emissions, eases paint
application by requiring fewer paint passes to obtain
coverage, and saves on both material and clean-up
time.
See the HVLP–Turbine Gun manual 309205 for more
information on the operation and use of the turbine
spray gun.
Unpacking Turbine Sprayer
Unpack the turbine sprayer from the shipping carton,
and inspect for any possible shipping damage. If there
is any damage, call your distributor.

Grounding
WARNING
Improper installation or alteration of the grounding
plug will result in a risk of electric shock, fire or
explosion that could cause serious injury or death.
This equipment requires a 120V AC, 60 Hz, 15A circuit
with a grounding receptacle. See Fig. 2.
grounded outlets
grounding prong
Fig. 2
Extension cord must be 3-wire, 12 AWG, 50 ft (15 m)
or shorter.
Do not alter the ground prong or use an adapter.
Setup/Use Options
System HVLP Turbine Sprayers have a variety of user
options. See Fig. 3.
See the System ProCart manual 309247 for
information on compressor/cart setup and
operation.
Prepare the Fluid
Always strain the fluid before you spray; this
includes color, reducer, and hardeners if used.
When using a System HVLP Turbine Sprayer use a
slower-drying reducer or thinner to compensate for
the faster drying time caused by the warm air of the
turbine. Do not over reduce.
CAUTION
The performance of the turbine sprayer varies with
the viscosity of the material and the length of the
hose. Keep the hose short to prevent pressure drop.
Paint Reduction — Automotive Type Finishes
Reduce and catalyze all paint to manufacturer’s
specifications. To compensate for the faster drying
time of turbine systems, use a reducer that is one step
slower than what is used for conventional air spray.
Paint Reduction — Industrial or Domestic
Coatings
Reduce and catalyze all paint to manufacturer’s
specifications. If no reductions are given, first
thoroughly mix the fluid to be sprayed. Then gradually
mix in the proper reducer, testing the fluid until you
have the correct spraying consistency.
To test the consistency, remove the stir stick from the
thinned paint. When the paint stream running off the
stir stick breaks into droplets, the first few drops should
be about one second apart.
See the HVLP–Turbine Gun manual 309205 for
information on gun setup and operation.

Operating System HVLP Turbine Sprayer
WARNING
Sparks can be expected in the normal operation of
the turbine motor. These sparks can ignite fumes
from flammable liquids, dust particles, and other
flammable substances in the spray area. This can
cause serious injury and property damage. Be sure
to follow the precautions below:
When flammable liquid is sprayed or used for
flushing or cleaning equipment, the turbine must
be placed at least 20 feet (6.1 m) away from
areas where hazardous concentrations of
flammable vapors are likely to occur.
Use additional air hose if necessary to ensure
that the turbine is operated in a clean, dry, well
ventilated area.
System ProCartt Cold Weather Operation
The System ProCart uses a diaphragm compressor.
A new diaphragm may be stiff in cold weather. If cold
enough, the diaphragm is too stiff to allow the
compressor motor to start (the unit hums). If this
occurs, follow these steps:
1. Turn turbine and compressor OFF.
2. Unplug turbine from power source.
3. Pinch and remove filter by hand. Clean or replace
if dirty.
4. Hand spin cooling fan on compressor for a few
revolutions.
5. Reinstall filter.
6. Plug in turbine.
7. Turn turbine and compressor ON. If necessary,
repeat procedure.
Never place the turbine inside a spray booth!
Use this equipment outdoors or in extremely
well ventilated areas.
Avoid all ignition sources such as: static elec-
tricity from plastic drop cloths, open flames like
pilot lights, hot objects like cigarettes, arcs from
connecting or disconnecting power cords, and
turning light switches on and off. Extinguish or
remove all sources of ignition.
1. Turn turbine ON a few minutes before spraying to
allow warm-up.
NOTE: When the turbine is not in use for an extended
period of time, turn it off. The turbine does not shut off
automatically.
2. Be sure turbine filter is clean before operating. See
page 11 to check and clean filter.

Maintenance
Daily
The System HVLP Turbine Sprayers are lifetime
lubricated. The only maintenance required is filter
cleaning and replacement.
The turbine filter must be clean at all times to provide
sufficient air flow to cool motor and atomize the fluid.
Check turbine pre-filter (22) daily for cleanliness.
Check the main paper filter (21) weekly, minimum.
Clean as necessary.
NOTE: To check filter, turn on turbine and place piece
of paper against pre-filter. If air intake holds paper in
place, filter is okay.
System 3800 and System 4900 models have an
air filter indicator light on the front panel. If the filter is
good the light is out. If the filter is clogged or has low
airflow the light will come on as in Fig. 7 below.
