Multi-Purpose Spray Gun

Spray Gun Terms (Continued)

type of operation is used with a compressor equipped with a tank or with a large factory air system. Do not use with a continuous run compressor that does not have a tank.

VISCOSITY – A measurement of the resistance of the flow of a liquid.

ATOMIZATION - Conversion of liquid to spray droplets (mist).

PATTERN CONTROL KNOB – Used to form the proper pattern (size and shape) of material as it is sprayed from the gun to the work piece.

FLUID CONTROL KNOB – Used to control the amount of material being mixed with air.

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

1. Read all manuals
included with this
product carefully. Be	MANUAL
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), Occupational Safety and Health Act (OSHA) and the Environmental Protection Agency (EPA).

! WARNING

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.

!DANGER

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.

! WARNING

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,

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.

! WARNING

Do not use pressure that exceeds the operating pressure of any of the

parts (hoses, fittings, etc.) in the painting system.

Keep hose away

! CAUTION 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.

NOTICE	Failure to install

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

Set Up

USE OF AIR CAPS

Internal Mix—Generally used with slow drying, heavy bodied materials and for faster material application. NOT to be used with fast drying paints and lacquers which will clog the opening in the air cap.

INTERNAL MIX CAPS MUST BE USED WITH PRESSURE FEED operation.

External Mix—Used for quick drying, light bodied materials such as lacquers and synthetic enamels.

Better for finer finish work. THESE

CAPS CAN BE USED WITH EITHER SIPHON OR PRESSURE FEED.

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 1). Hand tighten lock ring after adjustment.
