Spray Gun Terms (Continued)

PAINT TANK – An auxiliary pressurized paint reservoir that allows continuous spraying of large amounts of paint without stopping for refills as with a canister. It also allows using the spray gun at any angle or orientation.

General Safety Information

1. Read all manuals included with this product carefully.

MANUAL

Be thoroughly familiar with the controls and the proper use of the equipment.

2.Follow all local electrical and safety codes as well as in the United States, the National Electrical Codes (NEC) and Occupational Safety and Health Act (OSHA).

Use a face mask / respirator and protective clothing when spraying. Always spray in a

well ventilated area to prevent health and fire hazards. Refer to Material Safety Data Sheets (MSDS) of spray material for details.

Never spray closer than 25 feet to the compressor! If possible, locate compressor

in separate room. Never spray into the compressor, compressor controls or the motor.

3.Do not smoke or eat when spraying paint, insecticides, or other flammable substances.

Do not spray flammable materials in vicinity of open

flame or near ignition sources. Motors, electrical equipment and controls can cause electrical arcs that will ignite a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor.

4.When spraying and cleaning, always follow the instructions and safety precautions provided by the material manufacturer (Refer to MSDS).

Do not spray acids, corrosive materials, toxic chemicals, fertilizers or pesticides. Using

these materials could result in death or serious injury.

5.Keep visitors away and NEVER allow children or pets in the work area.

Never aim or

spray at yourself or anyone else or serious injury could occur.

6.Always work in a clean environment. To avoid injury and damage to the workpiece, do not aim the spray gun at any dust or debris.

Do not use pressure that exceeds operating pressure of any of the parts (hoses,

fittings, etc.) in the painting system.

Keep hose

away from sharp objects. Bursting air hoses may cause injury. Examine air hoses regularly and replace if damaged.

7.Always use a pressure regulator on the air supply to the spray gun.

Failure to install

appropriate water/oil removal equipment may result in damage to machinery or workpiece.

Do not misuse

this product. Excessive exposure to vibration, work in awkward positions, and repetitive work motions can cause injury to hands and arms. Stop using any tool if discomfort, numbness, tingling, or pain occur, and consult a physician.

Introduction

The spray gun is a vital link in any finishing application. In addition to operating the spray gun properly, techniques of surface preparation and paint preparation must be understood.

Spray Gun Set-Up

SIPHON FEED CUP SET-UP

The air pressure for atomization is controlled by the regulator on the air source. The amount of fluid is adjusted by the fluid control knob, the paint viscosity, and the air pressure (See Figure 1).

The siphon cup must be vented to the atmosphere.

Preparation

1.Thoroughly mix the paint in accordance with the manufacturer’s instructions, adding thinner where necessary. Most materials will spray

readily if thinned properly. Strain material through cheese cloth or a paint strainer. Test the consistency of the material by making a few strokes on a cardboard target. If material still appears too thick, add a small amount of thinner. THIN WITH CARE!!

2.Fill the canister about 3/4 full and start the air compressor.

3.Set up a piece of cardboard or other scrap material to use as a target and adjust for best spray pattern.

FAN DIRECTION

The direction of the fan (horizontal or vertical) can be changed by loosening the lock ring and turning the air cap 90 degrees (See Figure 2). Hand tighten lock ring after adjustment.

PATTERN ADJUSTMENT

Adjust air pressure to the spray gun according to the recommendations supplied with spray material. This air pressure usually falls between 40 - 60 psi. Adjust air pressure with trigger pulled and air control knob (if applicable) fully open. If reduced air pressure is desired for some areas of spray job, use air control knob to reduce pressure as necessary (See Figure 3).

Before spraying the workpiece, practice a few minutes on a cardboard target to ensure the pattern size and consistency are set correctly.
