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
