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. To 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.
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.
Fill the Cup or Remote Pressure Pot
Spray Gun Cup
WARNING
The spray gun cup is pressurized by the gun's air
supply. To reduce the risk of serious injury from
pressurized fluid or accidental spray from the gun,
always turn off 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
The remote pressure pots remain pressurized until
pressure is manually relieved. To reduce the risk of
serious injury from pressurized fluid or accidental
spray from the gun, always relieve pressure in the
pressure pot before loosening or removing the
cover.
1. Relieve the remote pressure pot pressure by
following these steps:
a. Turn off the air supply to the pressure pot.
b. 2 1/2 Gallon Remote Pot: Pull the pressure
relief valve ring (205) until pressure is com-
pletely relieved.
2 Quart Remote Pot: Turn out the pressure
relief knob (113) about one turn. Wait 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.
