Fine Adjustments of the Spray Gun

To improve the atomization, open the atomizing air valve further (31). If more atomizing air is needed beyond the fully open position of the valve, increase the air hose inlet pressure.

Use the lowest air flow settings needed for acceptable atomization. The slower particle velocity will improve the electrostatic effect.

To reduce the atomization air and minimize any overspray, turn the atomizing air valve in.

NOTE:

See the

Spray Pattern Troubleshooting chart on page 16 to correct spray pattern problems.

9. Turn the ES ON-OFF lever to ON to begin spraying with the electrostatics. When spraying, the ES indicator light (DD) should glow, indicating the electrostatic charge.

NOTE: To verify if you have enough air for full voltage, the Remote Spraying Voltage Readout (SVR ) monitor can be used. See Accessories . Watch the SVR display while increasing the air pressure to see if more air will increase the voltage.

10. Use the ES HI-LO lever (43g) to change to either full voltage (HI) or a lower voltage level (LO). The lower voltage setting is factory set to 60 kilovolts at zero microamperes. To change this setting, see page 27.

7. Set the atomizing air valve (31) about 1.5 turns out for most applications. The Atomizing Air Valve

Adjustment chart shows the effect of the atomizing air valve adjustment on the air cap air flow.

8. Adjust the pattern width with the fan air valve

(43c).

CAUTION

Always hang the gun with its nozzle pointing down when it is not being used to avoid having fluid run into the gun air passages. Fluid in the gun air passages can cause poor atomization and excessive current demands and damage the gun.

Electrical Tests

The performance and safety of the spray gun are directly affected by the condition of the electrical components contained inside the gun. The electrical tests below can be used to determine the condition of the power supply (18) and the resistor stud (22) as well as the continuity of the electrical path between the components.

Use megohmmeter P/N 241079 (A) and an applied voltage of 500 volts to complete these electrical tests.

Connect the leads as shown.

Measure the resistance between the end of the electrode (20) and the air fitting (17). The resistance should be between 329 to 401 megohms. If the resistance is outside the specified range, go to the next test. If the resistance is correct, refer to Electrical

Troubleshooting on page 18 for other possible causes of poor performance.

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.

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.
