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:
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.
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 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 off. Extinguish
or remove all sources of ignition.
Setup
1. Turn 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 off. The turbine does not shut off
automatically.
2. Be sure the turbine filter is clean before operating.
See page 12 to check and clean the filter.
NOTE: To adjust the spray gun pattern, see the
turbine gun manual 308–336.
Series 800 Cold Weather Operation
Turbine 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 stiff diaphragm will not allow the compres-
sor to start (the unit will hum). If this occurs, follow
these steps:
1. Turn the turbine and compressor off.
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.
