MBC-510 SPRAY GUN

IMPORTANT: Before using this equipment, read all safety precautions and instructions.

Keep for future use.

This gun may be used with chlorinated solvents. Aluminum is not used in the fluid passage areas.

DESCRIPTION

Note

Note

When replacing the fluid tip or fluid needle, replace both at the same time.

Using worn parts can cause fluid leakage. For thinner, less viscous materials a lapped tip and needle set is recommended. See Chart 3. Also, replace the needle packing at this time. Lightly lubricate the threads of the fluid tip before reassembling.

Torque to 20-25 ft. lbs. Do not over tighten the fluid tip.

The MBC-510 standard spray gun has a removable sprayhead; nickel plated brass fluid passages; a stainless steel fluid tip and needle to reduce wear; forged aluminum gun body; large air and fluid passages for high capacity use and a cartridge type air valve to minimize repairs.

Nozzle combinations are listed in Chart 1.

Refer to the Spray Gun Catalog, I-2008, for information regarding air cap and fluid tip characteristics.

To prevent damage to the fluid tip (5) or fluid needle (11), be sure to either

1) pull the trigger and hold while tightening or loosening the fluid tip or 2) remove fluid needle adjusting screw (32) to relieve spring pressure against needle collar.

Adjust fluid pressure to deliver the desired paint volume. Adjust air pressure and flow to provide a uniform dispersion of atomized paint throughout the pattern. Keep air pressure as low as possible to minimize bounce

- back and overspray. Excessive fluid flow will result in heavy center spray patterns.

Inadequate flows may cause the pattern to split. See Spray Gun Guide, SB-2-001, which is available upon request, for details concerning set up of spray guns.

SPRAY GUN LUBRICATION

OPERATION

Strain material thru 60 or 90 mesh screen.

PREVENTIVE MAINTENANCE

Daily, apply two drops of •SSL-10 spray gun lube (see Accessories) at trigger bearing stud

(34) and the stem of the air valve (15) where it enters the air valve assembly. The shank of the fluid needle (11) where it enters the packing nut (10) should also be oiled. The fluid needle packing (9) should be kept soft and pliable by periodic lubrication. Make sure the sprayhead (8) and retaining ring (1 or 2) threads are clean and free of foreign material. Before assembling retaining ring to sprayhead, clean the threads thoroughly, then add two drops of SSL-10 spray gun lube to threads. The fluid needle spring (31) and air valve spring (16) should be coated with a very light grease, making sure that any excess grease will not clog the air passages. For best results, lubricate the points indicated, daily.

To clean air cap and fluid tip, brush exterior with a stiff bristle brush. If necessary to clean cap holes, use a broom straw or toothpick.

Never use a wire or hard instrument. This may scratch or burr holes causing a distorted spray pattern.

• Material Safety Data Sheet available from

DeVilbiss upon request.

To clean fluid passages, remove excess material at source, then flush with a suitable solvent using a device such as the

SolventSaver™ (see Accessories). Wipe gun exterior with a solvent dampened cloth.

Never completely immerse in solvent as this is detrimental to the lubricants and packings.

SAFETY PRECAUTIONS

This manual contains information that is improtant for you to know and understand. This information relates to USER SAFETY and

PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the following symbols. Please pay particular attention to these sections.

Important safety information - A hazard that may cause serious injury or loss of life.

Important information that tells how to prevent damage to equipment, or how to avoid a situation that may cause minor inury.

Note

Information that you should pay special attention to.

The following hazards may occur during the normal use of this equipment. Please read the following chart before using this equipment.

HAZARD CAUSE

Fire Solvent and coatings can be highly flammable or combustible especially when sprayed.

SAFEGUARDS

Adequate exhaust must be provided to keep air free of accumulations of flammable vapors.

Smoking must never be allowed in the spray area.

Fire extinguishing equipment must be present in the spray area.

Solvent

Spray

Inhaling Toxic

Substances

Explosion Hazard -

Materials

General Safety

During use and while cleaning and flushing, solvents can be forcefully expelled from fluid and air passages. Some solvents can cause eye injury.

Certain materials may be harmful if inhaled, or if there is contact with the skin.

Halogenated hydrocarbon solvents - for example; methylene chloride and 1, 1, 1 -

Trichloroethylene are not chemically compatible with the aluminum that might be used in many system components. The chemical reaction caused by these solvents reacting with aluminum can become violent and lead to an equipment explosion.

Improper operation or maintenance of equipment.

Wear eye protection.

Follow the requirements of the Material Safety Data Sheet supplied by your coating material manufacturer.

Adequate exhaust must be provided to keep the air free of accumulations of toxic materials.

Use a mask or respirator whenever there is a chance of inhaling sprayed materials. The mask must be compatible with the material being sprayed and its concentration. Equipment must be as prescribed by an industrial hygienist or safety expert, and be

NIOSH approved.

The MBC-510 can be used with these solvents.

However, aluminum is widely used in other spray application equipment - such as material pumps, regulators, valves and cups.

Check all equipment items before use and make sure they can also be used safely with these solvents. Read the label or data sheet for the material you intend to spray. If in doubt as to whether or not a coating or cleaning material is compatible, contact your material supplier.

Operators should be given adequate training in the safe use & maintenance of the equipment (in accordance with the requirements of NFPA-33, Chapter 15). Users must comply with all local & national codes of practice & insurance company requirements governing ventilation, fire precautions, operation, maintenance and housekeeping.

These are OSHA Sections 1910.94 and 1910.107 and NFPA-33.

Cumulative Trauma

Disorders (“CTD’s”) musculoskeletal disorders, involve damage to the hands, wrist,

Use of hand tools may cause cumulative trauma disorders (“CTD’s”).

CTD's when using hand tools, tend to affect the upper extremities. Factors which may increase the risk of developing a CTD include: elbows, shoulders, neck and back. Carpal 1. High frequency of the activity. tunnel syndrome and 2. Excessive force, such as gripping, pinching, tendinitis (such as or pressing with the hands and fingers. tennis elbow or rotator 3. Extreme or awkward finger, wrist, or arm.

cuff syndrome) are positions. examples of CTD’s.

4. Excessive duration of the activity.

5. Tool vibration.

6. Repeated pressure on a body part.

7. Working in cold temperatures.

Pain, tingling, or numbness in the shoulder, forearm, wrist, hands or fingers, especially during the night, may be early symptoms of a CTD’s, or

CTD. Do not ignore them. Should you experience any such symptoms, see a physician immediately. Other early symptoms may include vague discomfort in the hand, loss of manual dexterity, and nonspecific pain in the arm. Ignoring early symptoms and continued repetitive use of the arm, wrist & hand can lead to serious disability.

Risk is reduced by avoiding or lessening factors 1-7.

CTD’s can also be caused by such activities as sewing, golf, tennis bowling, to name a few.

Remedies for the top-heavy, bottom-heavy, right-heavy and left-heavy patterns:

1) Determine if the obstruction is on the air cap or the fluid tip. Do this by making a test spray pattern. Then, rotate the cap one-half turn and spray another pattern. If the defect is inverted,

obstruction is on the air cap. Clean the air cap as previously instructed.

2) If the defect is not inverted, it is on the fluid tip. Check for a fine burr on the edge of the fluid tip. Remove with #600 wet or dry sand paper.

3) Check for dried paint just inside the opening. Remove paint by washing with solvent.
