Note: To achieve the best results when spraying it is always best to start with the air brush clean and totally free from old paint deposits, dirt
etc. Therefore the air brush should be thoroughly cleaned immediately after each operation.
5.1 Remove the excess paint from the paint pot, wipe the inside thoroughly, including the lid.
5.1.1. Fill the gravity feed pot half full of a compatible solvent.
5.1.2. Spray into a suitable container, this will clean the needle and nozzle assembly. Hold a soft cloth over the fixing nut and spray again, this
will force air and the compatible solvent back through the air brush and clean the internal moving parts.
5.2 Should the air brush become clogged with paint, dismantle the air brush and clean the component parts as follows: (Note:
Numbers in brackets refer to item numbers on the parts diagram).
5.2.1. Turn off the air and disconnect the air hose from the air brush.
WARNING! The fluid needle has a long sharp point and great care should be exercised when handling it.
5.2.2. Unscrew the back cover (16) from the main body of the air brush and slide it off.
5. MAINTENANCE
5.2.3. Unscrew the needle fixing screw (13) and slide it off the needle. Carefully withdraw the fluid needle (5) and place it somewhere safe to
avoid bending it or damaging the sharp point.
5.2.4. Unscrew the nozzle caps (1,2) from the front of the air brush.
5.2.5. Loosen the nozzle assembly (3) with the wrench provided and unscrew it. If the nozzle needs to be soaked in solvent remove the ‘O’
ring (6) as it may be damaged by the solvent.
5.2.6. Unscrew the needle guide assembly (12, 13, 14 & 15) from the rear of the air brush body. Test the action of the sprung plunger. If this
operates smoothly no further disassembly is required.
5.2.7. The trigger (9) and curved lever (10) will now be loose in the body and should be removed.
5.2.8. Any components with dried paint on them should be cleaned with a solvent suitable for the paint last used and may need to be soaked
for a while before the paint will come off. Take great care not to bend the needle when cleaning it and avoid the sharp point.
5.3. Reassemble the cleaned air brush as follows:
5.3.1. Replace ‘O’ ring (6) onto the nozzle assembly (3) and screw nozzle into place on body (8A).
Do not overtighten as this may restrict the effectiveness of the spray pattern.
5.3.2. Position the trigger (9) into the opening in the top of the air brush so that it sits on top of the air valve.
The slot in the stem of the trigger should be orientated to allow the needle to pass through it when the needle is re-inserted.
5.3.3. Insert the trigger guide (10) into the rear opening of the air brush body such that the convex face of the upper section rests against the
trigger.
5.3.4. Screw the needle guide assembly (12, 13, 14 & 15) into the back of the air brush until it makes contact with the curved lever (10).
Continue to screw it in until the trigger moves forwards.
5.3.5. Carefully insert the needle into the needle guide assembly and push it through until the needle tip just emerges from the nozzle
assembly (3). Do not force it into position but allow the needle to ‘rest’ in place.
5.3.6. Slide the needle adjuster screw (17) over the end of the needle and screw it into the rear of the needle guide assembly.
5.3.7. Test the action of the trigger to ensure that the needle withdraws smoothly into the nozzle as the trigger is pulled back.
5.3.8. Screw the nozzle caps (1,2) onto the nozzle. Do not do them up too tightly. Screw the back cover (16) onto the back of the air brush
body.
