633629 Air Sandblasting Kit
Note: It is recommended to use conductive hose to connect the
sandblasting gun and Suction Nozzle.
3. Fill a suitable container with abrasive material
4. Immerse the Suction Nozzle in the abrasive material, so that the tip of
the Deaeration Pipe (9) protrudes above the surface of the
abrasive material
Preparing the workpiece
• Workpieces contaminated with oil and grease should be degreased prior
to sandblasting
• Remove dirt and other encrustations (e.g. dried mud, soil) from surfaces
before sandblasting
• Carefully cover areas of the workpiece that must not be sandblasted
(e.g. insides of engine blocks, cylinder bores, and other
functional surfaces)
Operation
WARNING: Always wear personal protection equipment, including eye
protection, suitable gloves and adequate respiratory protection,
when working with this sandblaster.
1. Connect the sandblasting gun to the air supply
2. Adjust the air supply pressure according to the workpiece and
abrasive used
WARNING: Ensure the air supply pressure does not exceed the maximum
operating pressure stated in ‘Specification’
WARNING: Ensure the pressure is suitable for the workpiece and does
not damage the surface. ALWAYS test the effect of the abrasive on a scrap
piece of material, or begin sandblasting at an inconspicuous place on the
workpiece before starting the main job.
3. Direct the Outlet Nozzle (1) towards the workpiece, and press the
Trigger (4) to start the flow of abrasive
Note: When the Suction Nozzle (7) and Rubber Hose (6) are empty, it may
take a few seconds for the abrasive to start flowing into the sandblasting
gun. Keep the Trigger depressed until the abrasive exits the Outlet Nozzle.
4. Release the Trigger to stop sandblasting
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
cleaning or carrying out any maintenance.
Note: There is very little that can go wrong with your air tool and it should
be noted that when an air tool fails to work it is generally because the
internal workings have corroded due to dirty, wet air and failure to follow
the operating instructions.
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts
to wear quickly, and shorten the machine’s service life. Clean the body of
your machine with a soft brush, or dry cloth
1. Before disassembly, reconnect the sandblasting gun to the air supply
2. Remove the Suction Nozzle (7) from the abrasive container
3. Direct the Outlet Nozzle (1) towards a safe place, and blow it through
with air until all remaining abrasive is removed
4. Disconnect from the air supply
5. Remove the Rubber Hose (6) from the Material Hose Connector (3) and
Suction Nozzle Hose Connectors (8)
6. Remove the Nozzle Locking Ring (2) and Outlet Nozzle (1).
Disassemble other components as necessary, referring to the
‘Assembly Diagram’
7. Clean the whole route of abrasive material thoroughly, taking care not
to damage the Outlet Nozzle (1) and other internal parts
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.
8. Slightly lubricate all sealing surfaces and moving components with a
suitable spray gun lubricant
9. Reassemble the sandblasting gun, referring to the ‘Assembly Diagram’
Replacing the Outlet Nozzle
1. Disconnect the sandblasting gun from the air supply
2. Disconnect the Rubber Hose (6) from the sandblasting gun
3. Remove the Nozzle Locking Ring (2) and Outlet Nozzle (1)
4. Clean all threads and sealing surfaces
5. Install a new Outlet Nozzle, refit the Nozzle Locking Ring and
tighten securely
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 sealing surfaces, 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
• As with other power tools, air tools should not be disposed of with
household waste
• Air tools may contain traces of tool oil and other lubricants and so must
be recycled accordingly
• Contact your local waste disposal authority for information on the correct
way to dispose of power tools
• Surplus abrasive may be contaminated with the material it was used to
remove. Recycle or dispose of accordingly
