General Information
HVLP Turbine Sprayers
The GTS-2500, GTS-3800, and GTS-4900 HVLP
Turbines, compressor/cart, and spray guns 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 GTS-2500; 6 psi (0.4 bar, 41 kPa) for
GTS-3800; and 8 psi (0.5 bar, 55 kPa) for GTS-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 turbine gun manuals 308336 or 308810 for more
information on the operation and use of the turbine
spray gun.
Unpacking Turbine
Unpack the Graco 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.
Fig. 2
grounding prong
grounded outlets
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
HVLP Turbine Sprayers have a variety of user options.
See Fig. 3.
DSee compressor/cart manual 308809 for
information on compressor/cart setup and
operation.
DSee turbine gun manual 308336 or 308810 for
information on turbine spray gun setup and
operation.
Prepare the Fluid
DAlways strain the fluid before you spray; this
includes color, reducer, and hardeners if used.
DWhen using a turbine spray system, 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.

Operating Turbine
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:
DWhen 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.
DUse additional air hose if necessary to ensure
that the turbine is operated in a clean, dry, well
ventilated area.
DNever place the turbine inside a spray booth!
Use this equipment outdoors or in extremely
well ventilated areas.
DAvoid all ignition sources such as: static
electricity 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.
NOTE: To adjust the spray gun pattern see the turbine
gun manual.
HVLP Compressor/Cart Cold Weather
Operation

Maintenance
Daily
The turbine systems 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.
Models GTS-3800 and GTS-4900 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.
