1.1. ELECTRICAL SAFETY
ONLY USE THE SUPPLIED TRANSFORMER PLUG FOR CONNECTING UNIT TO THE MAIN ELECTRICAL POWER SUPPLY.
WARNING! It is the user’s responsibility to read, understand and comply with the following electrical instructions:
You must ensure the risk of electric shock is minimised by the installation of appropriate safety devices. An RCCB (Residual Current Circuit
Breaker) should be incorporated in the main distribution board. We also recommend that an RCD (Residual Current Device) is used with all
electrical products, particularly portable equipment which is plugged into an electrical supply not protected by an RCCB.
You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by
a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance
and the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. You must ensure that you:
Inspect the transformer plug, cable and connector for wear and damage to ensure items are safe before connecting to the mains power
supply. If worn or damaged DO NOT use but immediately replace, or contact a qualified electrician.
Check cables are always protected against short circuit and overload.
Important: Check that the voltage marked on the transformer plug is the same as the power supply to be used.

2. DESCRIPTION & SPECIFICATION
Heavy-duty steel cabinet with toughened glass viewing screen and integral low voltage
illumination. Double side doors on Model No. SB974 provide easy access for bulkier items.
Includes dust extraction port. Heavy gauntlets provide hand protection and each cabinet is
supplied with sand blasting gun and four ceramic nozzles. Suitable for proprietary brands of glass
beads, silicon carbide, aluminium oxide and silica sand only. Excellent for a wide variety of
workshop and bodyshop cleaning applications the cabinet requires a minimum 5hp compressor
with a DRY AIR SUPPLY.
3.2.6. Use an appropriate coupling suitable for your air system to
connect to the 1/4” inlet air coupling on the gun.
Pass the air line through the cabinet inlet hole (D).
3.2.7. Ensure the air gun (8) trigger is ‘Off’ before connecting to the air supply.
3.2.8. Check all fittings to ensure there are no leaks and check that the media supply hose is tightly attached to the underside of the gun.
3.2.9. Place abrasive into the centre of cabinet funnel, by pouring through the side door, until it is half full.
DO NOT exceed the stated amount. Excessive amounts of abrasive will impair visibility, create poor blasting performance and could
block the air exhaust at the rear of the cabinet.
3.2.10. Plug the transformer connector into the electrical inlet (E) at the rear of the blast cabinet. Plug the transformer into the mains socket.
3.3. Dust extraction: If not using an extraction system, remove the cover from air flow outlet (Z) at rear right hand side of the cabinet to
allow air flow.
3.3.1. We strongly recommend that a suitable dust extraction system is used with this unit.
The blast cabinet should be connected to a dust extraction unit. To do so, remove the plastic sealing plate (X) from the rear of the
cabinet and use the same screws to attach the plastic dust outlet. Fit a filter over the dust outlet to ensure that no abrasive is taken
into the extraction unit. Finally, connect the outlet to the extraction unit and use in accordance with the extractor instructions.

6. TROUBLESHOOTING
4.3. Place the workpiece in the centre of the cabinet and ensure you close and latch both side doors.
WARNING! Failure to securely close the doors could result in damage and/or personal injury.
4.4. Turn on the mains power supply and switch on the internal cabinet light.
Turn the air supply on (set to between 60-80psi). If attached, start the dust extraction unit.
4.5. Insert your hands into the rubber gloves inside the cabinet making sure that your fingers are correctly positioned and check that you
are able to easily move your hand and grasp objects correctly.
4.6. Grasp the gun with one hand and point the nozzle at the bottom of the cabinet. Depress the trigger to start the blasting process and
check to ensure everything is working correctly. If there are any leaks, stop and fix before use. If no flow is achieved, momentarily
cover the gun nozzle in order to force the compressed air back through the grit hose to clear any lodged media.
4.7. Hold the work piece with the other glove. Hold and move the workpiece to ensure you keep glove and fingers out of the abrasive blast.
DO NOT aim the blast at your fingers, gloves or the internal light.
4.8. Aim the nozzle directly at the surface of the workpiece and move the blast media (which looks like steam) continuously over the
workpiece in an even and circular motion. To avoid undesirable peening, the flow should not be too hard or concentrated. The work
finish may vary from coarse to fine depending on the size of the abrasive media. On delicate workpieces, to avoid unnecessary
peening or excessive abrasion, begin the blasting with a low airflow.
4.9. Before opening the cabinet to check progress or to access content, release the trigger and lay the gun on the mesh shelf. Remove your
gun hand first and then your other hand. Only then is it safe to open the side door.
4.10. When work is complete, disconnect gun from the air line, unplug from the mains electrical supply and switch off dust extraction.
5. MAINTENANCE
WARNING! Ensure the cabinet is disconnected from the electrical mains and the air supply before attempting any maintenance.
5.1. Keep the blast cabinet clean and dry. Do not use abrasives to clean the unit.
5.2. Ensure the blasting media does not become damp. Keep the air supply dry at all times. Dispose of any damp media.
5.3. Replace media when it has become excessively dusty, lost its granular or spherical appearance, or when workpiece debris has mixed
in with it. This is usually noticed when media from the nozzle looks like a smoke cloud rather than steam.
5.4. To change media, place an appropriate container under funnel outlet and turn the locking lever to open. Wear a dust mask when
performing this task.
5.5. If used, regularly check that the exhaust vent at the back of the cabinet (fig 1.Z) is clear.
If you use an extraction unit change the filter from time to time, according to use.
5.6. Regularly check gun blast nozzle to ensure that it does not become blocked with media. Immediately replace worn or damaged nozzles.
5.7. If the abrasive pick-up hose becomes blocked, ensure the doors are correctly closed and then re-power the unit. Cover the gun tip to
force air back through the hose to clear any media.
5.8. The transparent screen has a replaceable covering on the underside of the lid. If visibility is reduced, replace the protective cover.
5.9. Check that the gloves are in good condition. If damaged, replace immediately.
5.10. To replace internal cabinet light:
Un-clip light unit from each end clamp. Remove each plastic end (these are a tight fit). Disconnect the electrical terminals and gently
slip the rubber retaining rings from the tube releasing it from the back reflector. Use a light tube not greater than 70 watts.
