Gravity Feed Spray Gun 783124
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
1. Unscrew Paint Container Lid With Covered Equalisation Hole (1), empty
remaining material into a suitable sealed container, unscrew the
Paint Container (2) from the spray gun 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. Refit the paint container, fill with a small amount of solvent, close the
lid and open the equalisation hole cover
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. Open the paint container, empty remaining solvent into the disposal
container, and allow all components to dry thoroughly
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.
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 sharp points. 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.
Lubrication
• Even though the air and material passages of the spray gun must remain
free of oil and other contaminants, some components require frequent
lubrication
• Slightly lubricate all packings, bearings and dynamic O-rings with a
specialised spray gun lube, and apply a small amount of petroleum jelly
to springs
Storage
• Store this tool carefully in a secure, dry place, out of the reach of children
Disposal
• Air tools should not be disposed of with household waste
• Spray guns may contain traces of solvents and paint residue, and must
be recycled accordingly
• Surplus paints, solvents and cleaning solutions must be disposed of
according to the manufacturer’s instructions
• Contact your local waste disposal authority for information on the correct
way to dispose of air tools
