Intended Use
• Atomising suction feed spray gun, powered by filtered compressed air from a
compressor, for spraying of medium viscosity paint and coatings
Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features
and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are
missing or damaged, have such parts replaced before attempting to use this tool
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 some 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
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 (4) 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 Locking Lever (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 opening with the Equalisation Tube (3) attached. The paint
canister is therefore not completely sealed. Take care not to spill material through this tube.
Always ensure the hole in the lid and tube remain clean and unblocked.
Adjusting the spray gun
• Bring the spray gun into the default position:
1. Carefully screw the Knurled Needle Adjustment Screw (10) 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 (9) 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 (7) about a quarter turn, to allow the Air Nozzle
(6) to be adjusted
Adjust the material output:
1. Connect the spray gun to the air supply
2. Direct the gun towards a large piece of cardboard or similar material
3. Hold the spray gun steady and depress the Trigger (11)
Note: In default position, there should be no material output.
4. Slowly turn the Knurled Needle Adjustment Screw (10) anticlockwise to open the
material flow
5. Adjust until the desired material output is reached
Adjust the spray pattern:
Note: Always readjust the material output when modifying the width or shape of the
spray beam.
1. Slowly turn the Knurled Pattern Adjustment Screw (9) 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 (6) 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 (7) 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.
