WARNING
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury
.
D Ground the equipment and the object being sprayed. Refer to Grounding on page 8.
D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-
ing immediately . Do not use the equipment until you identify and correct the problem.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.
D When flammable liquid is sprayed or used for flushing or cleaning the 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 .
D
Use additional air hose if necessary to ensure that the turbine is operated in a clean, dry , well
ventilated area.
D Never place the turbine inside a spray booth! Use this equipment outdoors or in extremely well
ventilated areas.
D Keep the spray area free of debris, including solvent, rags, and gasoline.

General Information
The Series 700, 800 and 900 T urbine Spray Guns can
spray most coatings or finishes currently being used
for automotive refinish, industrial, aerospace, marine,
wood, plastic and architectural applications.
This spray gun typically utilizes 5 psi (0.34 bar) for
Series 700 and Series 800 and 6 psi (0.41 bar) for the
Series 900 inbound air pressure to produce high
quality paint finishes. The gun produces a cone of air
that 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 (vola
-
tile organic compounds) emissions, eases paint
application by requiring fewer paint passes to obtain
coverage, and saves on both material and clean-up
time.
Refer to the turbine gun manual, 308–336, for more
information on the operation and use of the turbine
spray gun.
Unpack the Graco T urbine Sprayer from the shipping
carton and inspect for any possible shipping damage.
If necessary , call your distributor .

NOT use a wrench to tighten connections; hand–
tighten only . See Fig. 1.
3. If using a spray gun cup (B), connect the cup to
the gun fluid inlet.
4. For Series 800 only: If using an accessory remote
pressure pot (C), connect the fluid supply hose (G)
between the gun fluid inlet and the remote pres -
sure pot.
Connect the air hose (E) between the pressure pot
air inlet and the compressor air outlet (F).
NOTES:
D
The circled letters in Fig. 1 indicate hose line con -
nections.
D
Only the Series 800 turbine unit includes a com -
pressor for use with a remote pressure pot.

Setup
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the turbine sprayer ,
ground the system as explained below .
Also read the section FIRE OR EXPLO -
SION HAZARD on page 2.
1. Turbine: Plug the turbine power supply cord into a
properly grounded outlet. Do not remove the
grounding prong from the power cord. Do not use
an adapter .
2.
Extension cords: Extension cords must have three
wires and be rated for a minimum of 15 amps.
3. Fluid supply container: follow your local code.
4. Object being sprayed: follow your local code.
Prepare the Fluid
1. Always strain the fluid before spraying; this
includes color , reducer and hardeners if used.
2. When using a turbine spray system, you need to
use a slower drying reducer or thinner to compen -
sate for the faster drying time caused by the warm
air of the turbine. Do not over reduce.
CAUTION
The performance of the turbine sprayer will vary
with the viscosity of the material. Unnecessary hose
length will cause the air pressure to drop.
Paint Reduction – Automotive Type Finishes
Reduce and catalyze all paint to manufacturer ’ s speci -
fications. T o compensate for the faster drying time of
turbine systems, use a reducer 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 speci -
fications. 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 .
T o test the consistency: Remove the stir stick from the
thinned paint. When the paint stream running of
f the
stir stick breaks into droplets, the first few drops should
be about one second apart.

Setup
Fill the Cup or Remote Pressure Pot
Spray Gun Cup
WARNING
The spray gun cup is pressurized by the gun’ s air
supply. T o reduce the risk of serious injury from
pressurized fluid or accidental spray from the gun,
always turn of f the air supply to the gun before
removing the spray gun cup.
Only fill the cup 3/4 full to help keep the air pressure
tube clean, then install the cover
. The under-cup cover
has a latch (H) to secure it to the cup. The over-cup
has a ring with notches (J) that secures the cup hood
into place when locked in place on the cup.

Accessory Remote Pressure Pot
WARNING
The accessory remote pressure pots remain pres -
surized until pressure is manually relieved. T o
reduce the risk of serious injury from pressurized
fluid or accidental spray from the gun, always
relieve pressure in the pressure pot before loosen -
ing or removing the cover .
1. Relieve the remote pressure pot pressure by
following these steps:
a. T urn of f the air supply to the pressure pot.
b. 2 Quart Remote Pot: T urn out the pressure
relief knob (1 13) about one turn. W ait until
pressure is completely relieved before remov -
ing the cover . Close the knob before using the
system again. See Fig. 3.

2. Remove the pressure pot cover and fill the pres -
sure pot. Secure the cover .
NOTE: 2 quart remote pressure pot only: lightly coat
the cover threads with petroleum jelly .
CAUTION
If the 2 quart remote pressure pot is accidentally
tipped over or held at too great of an angle, fluid may
leak into the air regulator . T ake precautions to avoid
this. If fluid does get into the regulator , clean it
immediately.
CAUTION
Do not tighten the pressure pot cover more than
hand-tight. Excessive tightening may damage the
cover gasket.

Setup
Prepare the Surface to be Sprayed
To achieve proper adhesion, make sure the surface to
be sprayed is completely clean.
Operating the Turbine
WARNING
Sparking can be expected in the normal operation
of the turbine motor . Sparks could ignite fumes
from flammable liquid, dust particles and other
flammable substances in the spray area, and
cause serious injury and property damage. Be sure
to follow the precautions below:
D 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 .
D
Use additional air hose if necessary to ensure
that the turbine is operated in a clean, dry , well
ventilated area.
D Never place the turbine inside a spray booth!
Use this equipment outdoors or in extremely
well ventilated areas.
DA void all ignition sources such as static electric -
ity from plastic drop cloths, open flames such as
pilot lights, hot objects such as cigarettes, arcs
from connecting or disconnecting power cords
or turning light switches on and of f. Extinguish
or remove all sources of ignition.
1. T urn the turbine on a few minutes before you start
spraying to allow for warm-up time.
NOTE: When the turbine is not in use for an extended
period of time, turn it of f. The turbine does not shut of f
automatically.
2. Be sure the turbine filter is clean before operating.
See page 12 to check and clean the filter .
NOTE: T o adjust the spray gun pattern, see the
turbine gun manual 308–336.
Series 800 Cold W eather Operation
T urbine Spray Model Series 800 has a diaphragm
compressor . When this compressors is new , the
diaphragm will become stiff in cold weather . If cold
enough, the stif f diaphragm will not allow the compres -
sor to start (the unit will hum). If this occurs, follow
these steps:
1. T urn the turbine and compressor of f.
2.
Unplug the turbine from the power source.
3. Loosen the four main filter screws and remove the
filter; replace the main filter and pre-filter if they
are dirty .
4.
Hand spin the cooling fan on the compressor for a
few revolutions.
5. Reassemble the turbine.
6. Plug in the turbine and turn compressor on. The
compressor should start.
