OPERATION AND MAINTENANCE INSTRUCTIONS

Your new Model 95G Gravity Feed Spray Gun is exceptionally rugged in construction and is built to stand up under hard, continuous use. However, like any other fine precision instrument, its most efficient operation depends on a knowledge of its construction, operation, and maintenance. Properly handled and cared for, it will produce beautiful, uniform finishing results long after other spray guns have worn out.

SET-UP FOR SPRAYING (Figure 1) CONNECTING GUN TO AIR HOSE

Air should be supplied by a suitable length of 5/16" diameter air hose fitted with a 1/4 NPS(f) connection at base of gun handle. For hose lengths over 50', use 3/8" hose.

CONNECTING GRAVITY FEED CUP TO GUN

Screw the cup into the spray gun fluid inlet. Fill the cup with filtered paint.

OPERATING THE MODEL 95G GRAVITY FEED SPRAY GUN

NOTE: All numbers in parentheses ( ) refer to item

numbers in assembly drawing on Page 6.

CONTROLLING THE MATERIAL FLOW

Correct fluid nozzle size should be selected for proper material flow rate. The material valve control knob (21) may be used to restrict the material needle valve opening and reduce the material flow as necessary.

CONTROLLING THE FAN SPRAY

The fan spray is controlled by means of the side port control assembly (9). Turning this control clockwise until it is closed will give a round spray. Turning it counterclockwise will widen the spray into a fan shape. The fan spray can be turned anywhere through 360° by positioning the air cap (2) relative to the gun. To affect this, loosen retainer ring, position nozzle, then tighten retainer ring.

TROUBLE SHOOTING

FAULTY SPRAY

A faulty spray is often caused by improper cleaning resulting in dried materials around the material nozzle tip or in the air nozzle. Soak these parts in thinners to soften the dried material and remove with a brush or cloth. If either the air cap (2) or fluid nozzle (3) are damaged, these parts must be replaced before perfect spray can be obtained.

INTERMITTENT SPRAY

Fluttering spray is caused by one of the following:

1. Insufficient material in cup. Refill the cup.

2. Loose fluid nozzle. Tighten snugly.

3. Cup connection loose or dirt in connection. Correct as necessary.

4. Air vent in gravity cup blocked. Clear obstruction.

SPRAY GUN CLEANING INSTRUCTIONS

In certain states, spraying solvents which contain Volatile Organic Compounds (VOC) into the atmosphere when cleaning a spray gun is now prohibited.

In order to comply with these new air quality laws, Binks recommends one of the following two methods to clean your spray finishing equipment.

1. Spray solvent through the gun into a closed system. An enclosed unit or spray gun cleaning station condenses solvent vapors back into liquid form which prevents escape of VOCs into the atmosphere.

2. Place spray gun in a washer type cleaner. This system must totally enclose the spray gun, cups, nozzles and

other parts during washing, rinsing and draining cycles. This type of unit must be able to flush solvent through the gun without releasing any VOC vapors into the atmosphere.

CLEANING GUN AND GRAVITY FEED CUP

Remove the cup cover and drain unused material from cup. Carefully rinse cup with solvent. Place clean solvent into the cup and spray this through the gun until it is clean. Remove and clean the cup if necessary. Blow air through the gun to dry it. (Refer to Service Bulletin SBBI4-043 for cleaning instructions when using cup liners.)

WARNING

Servicing the gun while pressurized could result in components or material exiting the gun at high velocity, possibly resulting in personal injury or damage to the spray gun. Before removing any components from the spray gun, shut off air pressure and drain material from the paint cup.

CAUTION

Never use metal instruments to clean the air or material nozzles. These parts are carefully machined and any damage to them will cause faulty spray.

Page 4

To reduce overspray and obtain maximum efficiency, always spray with the lowest possible fluid/air pressure that produces an acceptable spray pattern.

Excessive atomizing air pressure can increase overspray, reduce transfer efficiency and with some materials, result in poor finish quality from dry spray.

Generally use 30 to 35 psi air at gun inlet (see below). Unusually heavy, difficult to atomize materials may require up to 50 psi at gun inlet.

GENERAL SPRAY INSTRUCTIONS

The first requirement for a good resultant finish is the proper handling of the gun. The gun should be held perpendicular to the surface being covered and moved parallel with it. The stroke should be started before the trigger is pulled and the trigger should be released before the stroke is ended. This gives accurate control of the gun and material.

The distance between gun and surface should be 6 to 10 inches depending on material and atomizing pressure. The material deposited should always be even and wet. Lap each stroke over the preceding stroke to obtain a uniform finish.

SPRAY TECHNIQUE

OIL AND WATER EXTRACTOR IS IMPORTANT

Achieving a fine spray finish without the use of a good oil and water extractor is virtually impossible.

A regulator/extractor serves a double purpose. It eliminates blistering and spotting by keeping air free of oil and water and it gives precise air pressure control at the gun.

Atomizing pressure must be set to allow for the drop in air pressure between the regulator and the spray gun.

OIL AND WATER EXTRACTOR

HOSE SIZE RECOMMENDATIONS WITH 60 PSI APPLIED AT AIR SUPPLY

Only 34 psi at gun inlet

25 feet of 1/4" I.D. hose causes a drop of 26 psi between the air supply and the gun.

48 psi at gun inlet

25 feet of 5/16" I.D. causes a drop of 12 psi between the air supply and the gun. For this reason we recommend the use of 5/16" hose.

Tungsten Carbide Fluid Nozzle & Fluid Needle Tip

L-Series Fluid Nozzles tend to minimize “smoking effect” at the air cap allowing for less fluid build-up at the air nozzle horns. Typically, they require slightly higher air pressures to achieve the same fluid delivery as standard No. 60 Series nozzles.
