Prepare the Surface
To achieve proper adhesion, make sure the surface to
be sprayed is completely clean.
Turbine Operation
WARNING
Sparking can be expected in the normal operation
of the turbine motor. Sparks can ignite fumes from
flammable liquid, 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:
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 use or place the turbine inside a spray
booth! Use this equipment outdoors or in
extremely well ventilated areas.
D Avoid all ignition sources such as static
electricity from plastic drop cloths, open flames
such as pilot lights, hot objects such as
cigarettes, arcs from connecting or
disconnecting power cords, and arcs from
turning light switches on and off. Extinguish or
remove all sources of ignition.
1. Turn turbine on a few minutes before spraying to
warm-up.
NOTE: Turn turbine off when not in use. Turbine
does not shut off automatically.
2. Be sure the turbine filter is clean before operating.
See Turbine Filter Maintenance on page 13.
Setup
HVLP Compressor/Cart Cold Weather
Operation
The HVLP compressor/cart uses a diaphragm
compressor. When new, the diaphragm may become
stiff in cold weather. If cold enough, the diaphragm will
not allow the compressor motor to start (the unit will
hum). If this occurs, follow these steps:
1. Turn turbine and compressor OFF.
2. Unplug turbine from power source.
3. Pinch and remove filter by hand. Clean or replace
if dirty.
4. Hand spin cooling fan on compressor for a few
revolutions.
5. Reinstall filter.
6. Plug in turbine.
7. Turn turbine and compressor ON. If necessary,
repeat procedure.
Adjust the Pattern Direction and Shape
Spray pattern direction and shape are determined by
3 different positions of the air cap. See Fig. 5. Rotate
air cap as needed to achieve desired pattern.
NOTE: Do not loosen air cap retaining ring to change
patterns unless air cap is set to its widest pattern. See
Fig. 10 on page 9.
