Setting the air pressure
• Atomising pressure must be set properly to allow for the drop in air pressure between the
compressor/regulator and the spray gun
• Use recommended hose diameter to minimise pressure drop and adjust supply air pressure
according to 'Specification'
IMPORTANT: To reduce overspray and to obtain maximum efficiency, always spray with the lowest
possible atomising air pressure.
Paint preparation
WARNING: Ensure the type of paint, solvent used and the viscosity is suitable for the material
and type of this spray gun.
• Mix, condition and filter the material to be sprayed according to the manufacturer's
recommendations
• Refer to the manufacturer's guidelines for storing and disposal of prepared material
Filling the paint container
1. Ensure the spray gun is disconnected from the air supply
2. Open the Lid with Bayonet Closure (2)
3. Inspect the seal inside the Lid for wear and damage
4. Fill the Paint Container (1) to the required level
Note: The maximum filling height is approximately 10mm below the shoulder of the cup
5. Re-fit the Lid of the Paint Container. Close tightly by hand
Note: The Lid features a small hole for pressure equalisation and is therefore not completely
sealed. Take care not to spill material through this hole. Always ensure the hole remains clean and
unblocked.
Adjusting the spray gun
Note: Familiarise yourself with the 'Trigger operation' in the 'Operation' section below, before
commencing with the adjustment procedure.
Default Setup
1. Carefully screw the Knurled Needle Adjustment Screw (9) clockwise until it stops
WARNING: The paint needle can easily be damaged. Be careful not to use too much force.
2. Carefully screw the Knurled Pattern Adjustment Screw (7) clockwise until it stops
WARNING: DO NOT use too much force, as this may damage the valve seat.
3. Loosen the Air Nozzle Locking Ring (6) about a quarter turn, to allow the Air Nozzle (5) to be
adjusted
Adjust the material output
1. Connect the spray gun to the air supply, which has been adjusted according to 'Specification'
2. Direct the gun towards a large piece of cardboard or similar material
Note: In default setup, there should be no material or air output.
3. Hold the spray gun steady and fully depress the Trigger (11)
4. Keeping the Trigger depressed, slowly turn the Knurled Needle Adjustment Screw (9)
anticlockwise to open the material flow.
5. Adjust until the desired material output is reached
Adjust the spray pattern
Note: Always read just the material output when modifying the width or shape of the spray beam.
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 (Fig. III).
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 (11) 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
Spray technique
WARNING: Be aware that air tools may hold residual pressure after use. Always bleed air
pressure from the tool after shutting off air supply.
• To achieve a smooth even coat the material must be prepared and thinned in accordance with
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 (Fig. IV).
• Do not operate in an arc motion. Arcing will lead to an uneven finish (Fig. V).
• Avoid intensive waving, as it will cause the air jacket to become unstable, allowing clouds of
atomised 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 disassembling 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 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
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.). Make yourself
familiar with local regulations, and apply the recommended procedures.
1. Remove the Paint Container (1), 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
