JGA-510-DEC DECORATOR SPRAY GUN
IMPORTANT: Before using this equipment, read all safety precautions and instructions. Retain for future use.
DESCRIPTION
The JGA-510-DEC comes with the flatend AV-447 spatter cap assembly.
Small spatter dots are the result of coarse atomization when using the standard spatter cap assembly (2).
Adjust atomization air to get desired particle size. It should be high enough to carry particles to surface. Spatter dot size increases with pressure reduction, and decreases with pressure increase. Pressure used depends on material viscosity being sprayed and desired operation speed.
The JGA-510-DEC is a gun that can apply decorative spatter effects to wood furniture, metal panels, etc.
Finish may be changed from a fine mist to larger droplet size particles.
Simply adjust fluid pressure and/or air pressure
PREVENTIVE MAINTENANCE
To clean gun passages, blow back paint to material supply source and flush fluid passage with clean solvent.
Model HD-503 Gun/Hose Cleaner is a very fast and effective way of cleaning
(See Accessories). Wipe gun clean with solvent soaked cloth.
OPERATION
If slots of ring (4) become clogged, clean by soaking cap in solvent and scrubbing with a gun cleaning brush.
Note
Note
This gun may be used with chlorinated solvents. Aluminum is not used in the fluid passage areas.
Mix material according to manufacturer's instructions. It may be necessary to strain material.
When replacing the fluid tip or fluid needle, replace both at the same time. Using worn parts can cause fluid leakge.
Also, replace the needle packing at this time.
Using SSL-10 gun lube, lightly lubricate the threads of the fluid tip before reassembling. Torque to 12-15 ft. lbs.
A greater than normal gun distance provides a more uniform particle size.
Particle spacing is determined by speed of movement and degree of overlap.
Particle size is dependent on the material consistency. Specially formulated spatter materials are available, although standard paints may be used. Apply standard paints using very little or no reduction.
To prevent damage to the fluid tip (7) or fluid needle (28), be sure to either 1) pull the trigger and hold while tightening the fluid tip or 2) remove fluid needle adjusting screw to relieve spring pressure.
Pressure on cup or tank controls material flow. Begin with the fluid needle adjusting screw (32) wide open.
Use fluid needle adjusting screw (32) to regulate material flow under abnormally low material pressure or material viscosity conditions.
Spray Gun Lubrication
For best results, lubricate the points indicated, daily. Use SSL-10 Spray
Gun Lube to lubricate.

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
Fire
CAUSE
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.
Wear eye protection.
Solvent Spray
Inhaling Toxic Substances
Explosion Hazard -
During 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 - Trichloroethane can chemically react with aluminum.
The chemical reaction caused by these solvents reacting with aluminum can become violent and lead to an equipment explosion.
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 hygienst or safety expert, and be NIOSH approved.
This gun can be used with these solvents.
However, aluminum is widely used in other spray application equipment - such as, material pumps, cups, regulators, valves, etc. Check all other equipment items before use and make sure they can also be used safely with these solvents. Read the label or material 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.
