WARNING

Disconnect the spray gun from the air supply, and relieve any pressure in the

gun and hose, before any disassembly.

It is essential that the spray gun is kept clean. Dried paint in the nozzle assembly or airways

will stop the gun from working. For the gun to perform at its best it must be cleaned and

lubricated after every use.

After use, empty any remaining paint from the paint cup, wipe the cup clean with a dry,

lint free rag, and fill with thinners. Spray the thinners through the spray gun until it is clean.

1.

Immerse only the front end of the gun until solvent just covers the fluid connection.

NOTE : do not submerge the entire spray gun in solvent because :

a, the lubricant in the leather packings will dissolve and the packings will dry out.

b, the lubricant at wear surfaces will dissolve resulting in harder operation and

premature wear.

c, residue from dirty solvent may clog the narrow air passages in the gun.

2. Use a small bristle brush and solvent to wash off accumulated paint.

3. Wipe down the outside of the gun with solvent dampened cloth.

4. Lubricate gun daily, using a light machine oil on :

a, fluid needle packing

b, air valve packing

c, side port control packing

d, trigger pivot point

Coat the fluid control spring with vaseline.

CAUTION : never use silicon based lubricants as this may cause paint finish defects.

DO NOT poke any of the holes in the air cap or nozzle with metal instruments. These holes

are precision drilled, and can be damaged by probing with anything harder than a

wooden toothpick.

Make sure that the air inlet vent to the paint cup is kept clean. Blockages in this vent will

prevent an even material flow to the gun.

Do not mix components from spray guns, even those of the same type. Do not overtighten

components, and be careful not to cross thread any parts on assembly.

Check the air supply hose regularly for any signs of damage, and replace it if necessary.

Do not use damaged or leaking hoses.

MAINTENANCE

PAINT SPRAYING HINTS

WARNING

NEVER attempt to spray unless you are wearing suitable, approved

respiratory and eye protection.

REMEMBER that some modern paints require specialist respiratory

protection...always consult the paint manufacturers instructions.

1. General Preparation

a. Ensure that the area in which you will be spraying is clean and dust free.

b. Connect spray gun to compressor via suitable flexible hose.

c. With no paint in spray gun, test system for air leaks.

d. Cover adjacent pieces of equipment to prevent overspray. Mask areas

of the article not to be sprayed.

e. Ensure surface to be painted is clean, dry and free from oil and dust.

Check paint manufacturer’s instructions for any special surface

preparation required.

REMEMBER - TIME SPENT PREPARING SAVES TIME SPENT FINISHING

2. Paint Preparation

a. Achieve the correct paint viscosity. This should be done according to

paint manufacturer’s instructions, and will vary according to type of paint, (see

paint thinning on page 9).

b. Having mixed the paint thoroughly in a separate container, pour into the

spray gun paint container through a fine filter.

DO NOT OVERFILL SPRAY GUN PAINT CONTAINER - three quarters full is maximum

c. It is usually best to experiment with a couple of practice spray coats on a

piece of material with the same type of surface as the article you wish to

spray, eg. metal for a car body panel, wood for a piece of furniture etc.

d. Some common problems:
