Before Use
Fitting the quick connector
Note: This tool is supplied with two different male airline quick connectors:
EQ-4 – commonly used in Europe
EN-6 – mainly used in the UK
• Please choose the connector that is compatible with the airline system
you are using, and install as outlined below:
1. Apply PTFE tape (not included) to the screw threads of the Quick
Connector (13). This will help to maintain an air tight seal
Note: Apply PTFE tape tightly and in a clockwise direction, so it does not
come off when the thread is screwed into the tool.
2. Remove the protective plug from the air inlet (if fitted)
3. Using a spanner (not included) screw the quick connector into the air
inlet located at the base of the handle
4. Connect to airline, pressurise carefully and carry out a leak check (e.g.
by spraying small amounts of soapy water on to the outside of the
connectors)
• Air lines fitted with matching female quick connectors will now be a push
fit to the tool
Fitting the paint container
• Fit the Paint Container (1) by screwing it to the Fluid Connector (3) of the
spray gun. Gently tighten with a suitable spanner (not included)
Air supply connection
• This tool should be connected to a clean, dry air supply with water
separator and filter
WARNING: Under no circumstances can the spray gun be used in a
compressed air system with integrated oiler.
Note: Achieving a fine spray finish without the use of a high quality
separator filter is virtually impossible.
• Do not allow supply pressure to exceed the maximum stated (see
‘Specifications’)
• Ensure that water is drained from air system daily
• Ensure that all parts of the system (hoses, couplers, etc.) are correctly
rated for the air pressure to be used
• Do not use non-conductive tubing to help prevent build-up of
electrostatic charge
Setting the air pressure
• Atomizing 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 ‘Specifications’
IMPORTANT: To reduce overspray and in order to obtain maximum
efficiency, always spray with the lowest possible atomizing 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 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.
Bringing the spray gun into the default position:
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
Adjusting the material output:
1. Connect the spray gun to the air supply, which has been adjusted
according to ‘Specifications’
2. Direct the gun towards a large piece of cardboard or similar material
3. Hold the spray gun steady and fully depress the Trigger (11)
Note: In default position, there should be no material output.
4. Holding 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
Adjusting the spray pattern:
Note: Always readjust the material output when modifying the width or
shape of the spray beam.
