1. Slowly turn the Knurled Pattern Adjustment Screw (7) anticlockwise to
adjust the spray pattern. Turn until the desired spray pattern is reached
Note: Turning the pattern adjustment screw anticlockwise increases the
spread, turning it clockwise leads to a narrower, more circular spray pattern.
2. Turn the Air Nozzle (5) to adjust the orientation of the spray pattern
(see Fig. A)
3. Once you reached the desired spray pattern, release the Trigger (11)
and tighten the Air Nozzle Locking Ring (6) by hand, to lock the air
nozzle in place
Note: In most operations the wings on the air nozzle should be horizontal to
provide a vertical spray pattern which gives maximum coverage as the gun
is moved backwards and forwards parallel to the surface being painted.
Operation
Trigger operation
• The trigger has a 2-stage mechanism:
• Press to the first stage, the air will flow through the gun
• Press further and the paint is released
Note: Adjusting the Knurled Needle Adjustment Screw (9) will determine
how far the trigger can be depressed

• To achieve a smooth, even coat, the material must be prepared and
thinned in accordance to the manufacturer's guidelines
• The gun must be clean and correctly loaded, the spray pattern adjusted
and the compressor set at the correct pressure
• Always carry out a test spray and follow the procedures described in
'Adjusting the spray gun', to establish the best settings
• Keep the distance of the spray gun approximately 200-250mm away
from the workpiece
• Spray workpiece edges first. Overlap approximately 50% of each applied
spray beam
• Spray in continuous, even motion. Keep your hand as steady as possible
and move the spray in a straight pass across the workpiece (see Fig. B)
• Do not operate in an arc motion. Arcing will lead to an uneven finish
(see Fig. B)
• Avoid intensive waving, as it will cause the air jacket to become unstable,
allowing clouds of atomized spray material to escape
• Before spraying it is good practice to visualise the entire spraying
process. Start with the least visible areas and work towards the parts
that will be seen. This will create an even finish, allow you to identify
problematic areas of the workpiece, and let you work around spots that
may already have been covered
• After use, immediately disconnect the spray gun from the air supply

WARNING: Be aware that air tools may hold residual pressure after use.
Always bleed air pressure from the tool after shutting off air supply.
Maintenance
WARNING: Always disconnect from the air supply and depressurise before
disassembly or carrying out any maintenance.
WARNING: Always wear suitable protective equipment including eye and
respiratory protection as well as gloves when carrying out cleaning or
maintenance procedures.
WARNING: The majority of solvents used for painting applications are
toxic and highly flammable. Comply with local laws and regulations with
regards to handling, storage and disposal of solvents and other harmful and
potentially dangerous substances.
Note: Your spray gun is a fine precision instrument and must be treated and
maintained accordingly, in order to achieve consistent, professional-looking,
uniform results.
• The most common problems with spray guns are caused by paint being
allowed to dry inside the tip, nozzle or internal air/fluid passages
• Clean the entire spray gun thoroughly after each project, and also when
changing the type of material being sprayed
• Always use the same solvent for cleaning that was used to thin the paint
General cleaning after every use
1. Remove the paint container, empty remaining material into a suitable
sealed container, and clean thoroughly with the appropriate solvent
and clean cloths
2. Clean the nozzle assembly of the gun, lid and gasket of the paint
container
3. Pour a small amount of solvent into the clean paint container and re-fit
it to the gun
4. Connect the gun to the air supply
5. Direct the gun towards an empty container and spray the solvent
through the gun into the container, until the spray is clear of any paint
6. Turn off the air supply and disconnect the gun
7. Release the paint container, empty remaining solvent into the disposal
container, and let all components dry thoroughly
8. Re-fit paint container for storage
WARNING: In order to prevent solvents and other harmful substances from
entering the atmosphere, open solvent cleaning is not permitted in some
territories, and special cleaning procedures apply (e.g. cleaning inside
special closed bags and containers, etc.). Familiarise yourself with local
regulations, and apply the recommended procedures.
Special cleaning procedures for air and fluid nozzles and
needles
WARNING: All nozzles and needles are precision made. They must be
handled with the utmost care. Damage and alterations will cause decreased
performance or faulty spray.
WARNING: Needles have a sharp point. Handle with care to avoid puncture
wounds and other injuries.
1. Referring to the 'Assembly Diagram', carefully disassemble the spray
gun, remove the nozzle assembly and fluid needle
2. To clean, soak nozzles and needle in a suitable solvent that dissolves
any dried material and clean with a suitable soft brush
Note: Never soak the entire spray gun in solvent, as this will damage the
packings and remove lubrication.
3. Carefully blow all components clean with filtered compressed air
WARNING: Do not probe any of the holes in the nozzles with metal
instruments. If mechanical cleaning becomes necessary, use only
implements from materials softer than brass, such as specialised nozzle
cleaning aids.
