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.
Setup
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.
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.
T o 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.
