Gravity Feed Spray Gun
Intended Use
• Atomising gravity 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 PTFE tape (not included) to the screw threads of the Quick
Connector (8). 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 (2) by screwing it in to the opening on top of the
spray gun. Gently tighten with a suitable spanner (not included)
Note: Always inspect the O-ring on the paint container thread, and ensure it
is in good condition. Change if required.
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
• 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 ‘Specifications’
IMPORTANT: To reduce overspray and in order to obtain maximum
efficiency, always spray with the lowest possible 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. Unscrew the Paint Container Lid With Covered Equalisation Hole (1)
3. Fill the paint container to the required level
Note: The outside of the paint container features a scale in ml. Never overfill
(see ‘Specifications’ for max. paint container capacity).
4. Re-fit the lid of the paint container. Close tightly by hand
Note: The lid features a covered equalisation hole for pressure equalisation,
and is therefore not completely sealed. Take care not to spill material
through this hole. Open the lid before spraying, and close after you finished
work or before refilling the paint container. Always ensure the hole remains
clean and unblocked.
