/
2
-gallon remote pressure pot:
Set at 8 to 10 psi (0.56 to 0.70 bar).
NOTE: Heavier fluids or longer fluid hoses require greater pressures.
WARNING
Over-pressurizing the accessory remote pressure pots can cause serious injury. To reduce the risk, never exceed 50 psi (0.35 MPa,
3.5 bar) Maximum Inlet Fluid Pressure.
CAUTION
Restricting the trigger and fluid needle travel by continuously spraying with the fluid adjustment knob closed (turned clockwise), will cause accelerated abrasive wear on the fluid needle and wear on the trigger.
For best results, adjust fluid flow at the pressure source or use a different size needle/nozzle/air cap combination.

Setup
Adjusting the Pattern NOTES:
D Control over-spray mist by using only as much air as necessary to spray fluid. Lighter fluids require less air.
D If atomization is still unacceptable, fluids may be thinned further or a different fluid set may be required. Refer to page 8 to determine fluid set or page 9 to prepare fluid.
Spray Pattern Direction and Shape
The spray pattern and direction are determined by the pattern selection knob (A) fluid adjustment knob (21) and air cap (15) positions. See Fig. 6.
Change the pattern by adjusting the fluid knob (21) and pattern selection knob (A).
NOTE: Reducing the fluid flow rate or turning the air knob to RND will reduce the pattern width. Using air
cap 197056 will create a highly productive, wider pattern. See Fig. 8.
The air control (B) controls the TOTAL air to the pattern and gun. See Fig. 6.
As the fluid flow rate is reduced the pattern becomes smaller.

Selecting Fluid Sets
The Turbine Spray Gun includes a #3 fluid set, Part
No. 244124. Grooves at the end of the fluid needle
indicate the size of fluid set.
Setup
Turbine spray gun fluid sets range in size to provide different fluid flow rates. Selection charts on page 8 show recommended combinations based on fluid viscosities, flow rates, and usage.
Fluid sets include a nozzle (14a), o–ring (4) and needle assembly (14b). See Fig. 9.
NOTE: To order other replacement parts for gun, see parts drawing and list for gun model on page 23.
fluid set

Troubleshooting
Spray Finish Problems
PROBLEM
Orange peel finish — Paint surface not smooth
Blushing — Clear coatings appear milky
CAUSE
Paint droplets too large
Paint droplets drying too fast to properly flow out of gun
Cold weather spraying
Moisture condensation is trapped in the lacquer when spraying in hot, humid conditions
Fish eyes — Small pools on painted surface that will not fill
Silicone contamination from lubricants, grease, polish, or waxes on the surface being sprayed
Runs and sags
Solvent pops or bubbles
Applying too much paint per pass for the drying conditions
Sprayed surface drying before solvent gas can be released
SOLUTION
D Maintain proper spraying distance.
See page 12.
D Keep the turbine air filters clean to allow full air flow.
D Do not use an air hose that is too long to provide sufficient atomization pressure.
D If droplets are still too large, reduce the fluid.
Keep the object being sprayed out of direct sunlight. When spraying in warmer temperatures, use a slower evaporating solvent or a retarder.
Keep the fluid and the object being sprayed as close to room temperature as possible. When sprayed on a cold surface, most paints will become too thick to flow properly.
D Allow the turbine to warm up a few minutes before spraying.
D Store the lacquer off concrete floors, at room temperature.
D Apply lighter coats and allow for proper drying time.
D Use a slower evaporating solvent or retarder.
D Do not spray in windy conditions.
Clean all parts with a cleaning solvent; use a solvent rag and a clean rag to wipe with. Replace rags as needed. If the problem persists, use a fish eye eliminator.
D Move the gun faster or decrease the fluid flow.
D Maintain proper spraying distance.
See page 12.
D Reduce the amount of thinner or use a faster drying thinner.
D Apply fluid in lighter coats to allow for proper evaporation.
D Use the recommended thinners.
D Follow the solutions, above, for
Orange peel finish — Paint droplets
too large.

Troubleshooting
Spray Gun Problems
PROBLEM
No or slow fluid flow, intermittent spray, or fluttering spray
Fluid leaks at fluid nozzle after the trigger is released
Poor spray pattern
CAUSE
Wrong size fluid set being used or the o–ring on nozzle is missing
SOLUTION
Select the proper fluid set for the fluid being sprayed (see page 8) or put an o–ring on the nozzle.
Clean or replace fluid nozzle.

NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
