-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.

309205 19

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.

Gun fluid nozzle blocked by dried paint, or damaged

Cup or pressure pot cover not tight enough, or gasket damaged

Cup or pressure pot fluid tube blocked by dried paint or damaged

Air flow to cup blocked

Tighten cover or replace gasket.

Clean or replace fluid tube.

Needle packings not properly adjusted

NOTE: Fluid loss though the packings affects fluid pressure and causes a fluid leak from the gun body.

Plugged inlet strainer

Graco Standard Warranty

Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of

Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT

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

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

These items sold, but not manufactured by Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.

In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the negligence of Graco, or otherwise.
