General Safety
Any misuse of the spray equipment or accessories,
such as improper usage, over pressurizing, modifying
parts, using incompatible chemicals and fluids, or
using wornor damaged parts,can cause them to rupture and result
in serious injury, fire, explosion or
property damage.

When flammable liquid issprayed or used for
flushing or cleaning equipment, the turbine must
be placed at least20 feet (6.1 m) away from areas
where hazardous concentrations of flammable
vapors arelikely 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 insidea spray booth! Use
this equipment outdoors or in extremely well ventilated areas.
Grounding
To reduce the risk of static sparking, ground the turbine and all other spray equipment used or located in
the spray area. Check yourlocal electrical code for
detailed grounding instructions for your area and type
of equipment.
To ground the turbine: Plugthe power supply cord
into a properly grounded outlet. Do not remove the
grounding prong from the power cord.
Do not use an
adapter. Extension cords must have three wires and
be rated fora minimum of15 amps.
IMPORTANT
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards--particularly the General Standards,Part 1910 and the Construction Standards, Part 1926--should be consulted.

WARNING
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 compensate for the faster
drying timecaused by the
warm air ofthe turbine.Do not over reduce.
Paint Reduction - Automotive Type Finishes
Reduce and catalyze all paint
to manufacturer’s specof
ifications. To compensate for the faster drying time
turbine systems, usea 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 specifications. If no reductions are given, first thoroughly
in the
mix the fluid to be sprayed. Then gradually mix
proper reducer,testing the fluid until you
have thecorrect spraying consistency.
The accessory remote pressure pots remain pressurized until pressureis 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 thecover.
1. Relieve the remote pressurepot pressureby following these steps:
a. Turn off the air supply to the pressure pot.
b. 2 7/2 Gallon RemotePot: Pull the pressure
relief valvering (206c) until pressureis completely relieved.
2 Quart RemotePot: Turn out the pressure
relief knob (113) about one turn. Wait until
pressure is completely relieved before removing the cover. Close the knob before using the
system again.
See Fig. 4.
To test the consistency: Remove the stir stick from the
thinned paint.When the paint stream running
off the

should be about one second apart.

WARNING
The spray gun cup is pressurized by the gun’s air

1. Turn the turbine and compressorOff.
To achieve proper adhesion, make sure the Surface

2. Unplug the turbine from the power source.
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 substancesin the spray area, and
cause seriousinjury 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 likelyto occur.

Use additional air hose if necessary to ensure
that the turbineis operated in a clean, dry, well
ventilated area.

Never place the turbine insidea spray booth!
Use this equipment outdoors or in extremely
well ventilated areas.
Avoid all ignition sources suchas static elestricity from plastic drop cloths, open flames
such as pilot lights, hot objects such
as cigarettes, arcs from connecting or disconnecting
power cords orturning light switches
on and
off. Extinguishor remove all sources of ignition.
3. Loosen the four main filter screws and remove the
filter; replace the main filter and
prefilter ifthey
are dirty.
4. Hand spin the coolingfan on the compressor for
a few revolutions.
5. Reassemble the turbine.
6. Plug in the turbine and turn
it on. The compressor
should start.
Adjust the Pattern Direction and Shape
The spray pattern direction and shape are determined
by the3 different positions of the air
cap shown in Fig.
5. Rotate the air cap as needed
to achieve the desired
pattern.
NOTE You do not haveto loosen the air cap retaining
ring to change patterns unless the air cap
is set to its
widest pattern. Referto Fig. 11, page I O .
1. Turn the turbine on a few minutes before you start
spraying to allow for warm-up time. Turn the turbine off when it is not in use; it doesnot shutoff
automatically.
Round Pattern
2. Be sure the turbine filter is clean before operating.
See page 13 to check and clean the filter.
Cold Weather Operation
Turbine Spray Model CX-8, CX-12, and CX-20 havea
diaphragm compressor. When these compressors are
new, the diaphragm will become
stiff in cold weather.
If cold enough, the stiff diaphragm will not allow the
compressor to start (theunit will hum).If this occurs,

sprayed. See Fig.14.
General Spraying Techniques
1. Select the proper fluid set for the
fluid you are
spraying. See pages4 and 5.
2. When fluid is first being applied, start with the

Turbine Filter Maintenance
3. Remove the main filter and cleanit by following
one ofthe following three methods:
The turbine systems are lifetime lubricated. The only
maintenance requiredis filter cleaning andreplace
ment.
The turbine main filter and pre-filter must be clean
at
all timesto provide sufficient air flow
to cool the motol
and atomize the fluid. Check the filters weekly, minimum. Replace theprefilter as required.
NOTE To check the filter, turn on the turbine and
place a piece of paper against the air intake filter.
If
the air intake holds the paper
in place, the filteris
okay.
To clean themain filter:
1. Turn off and unplugthe turbine.
2. Loosen the four main filter screws.

The spray gun cups and accessory remote pres-
sure pots remain pressurizeduntil 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 cupor
pressure pot before checking

7. Disconnect the air and fluid hoses from the gun.
8. Clean and lubricate the gun as instructed on
pages 15 and 16.
Flushing the Spray Gun and Cup
1. Turn off the air supplyto the gun.
NOTES
0 Check for any fluid leakage from the gun and fluid
hoses. Tighten fittings
or replace equipmentas
needed.
Flush the gun before changing colors and whenever you are done spraying.
2. Unlatch the cup cover and remove the cup from

Adjusting the Needle
The needle may need
to be adjustedwhenever you
change nozzle/needle sizes to
or compensate for
wear.
To adjust the needle:
1. Remove the housing (22) from the back of the
gun. Thefluid adjustment knob(20), nut (21), and
spring (23-not shown) will come out with it. See

Adjusting the NeedlePackings
The needle packings require adjustment once a
month under normal use
to ensure fluid does not leak
back throughthe needle packings. The needle packings must alsobe adjusted wheneverthe needle is
removed or adjusted.
To adjust the needle packings:
1. First flush thegun as instructed on page14.
2. Remove the air cap retainingring (29), air cap
(27),spring (25), and detent plate(26). See Fig.
26.
3. Trigger the gun while you remove the fluid nozzle

4. Trigger the gun while you turn the packing
nut (9)
slightly clockwise with the packing wrench
(K),
provided. See Fig. 27. This will compress the
packings.
The packings need verylittle pressure toseal
well. If the needle binds, the packings too
are
tight; back the packing nut
off 1/16 turn. The
needle should then move freely. If the packings
are over-tightened, they may
be damaged and
need tobe removed and replaced.
