2. DESCRIPTION & SPECIFICATIONS
Your shot blasting cabinet is constructed of steel with a replaceable viewing screen and internal
illumination. Fitted with a shot blasting gun the unit is suitable for proprietary brands of glass
beads only. Excellent for use with a wide variety of workshop and bodyshop cleaning applications
The cabinet requires a minimum 3hp compressor with a DRY AIR SUPPLY.
3.2.6. Use an appropriate coupling suitable for your air system to
connect the air supply to the 1/4 inlet air coupling on the gun.
Pass the air line through the cabinet inlet hole (fig 4.D).
3.2.7. Ensure the air gun (fig 3.8) trigger is off before connecting to the air supply.
3.2.8. Check all fitting to ensure there are no leaks, and check that the media supply hose is tightly attached to the underside of the gun.
3.3. Shot Blast Media.
3.3.1. Place the abrasive media into the centre of the cabinet funnel by pouring through the side door until it is half full.
DO NOT over fill, as excessive amounts of media will impair visibility, create poor blasting performance and could block the air
exhaust at the rear of the cabinet.
3.3.2. Connect the transformer inlet socket to the electrical inlet on the side of the blast cabinet at point (fig 4.E).
3.3.3. If not using an extraction system, remove the cover from air flow outlet at rear right hand side of the cabinet (fig 4.Z) to allow air flow.
3.4. Dust Extraction.
The blast cabinet may be fitted to a dust extraction unit. To do so, remove the plastic sealing plate from the side of the cabinet (fig 4.C)
and use the same screws to attach the plastic dust outlet. Fit a filter over the dust outlet to ensure that no grit is taken into your
extraction unit. Finally, connect the outlet to your extraction unit and use in accordance with the extractors instructions.

4.2. Place the workpiece in the centre of the cabinet and ensure you close and latch side door.
pWARNING! failure to securely close the door could result in damage or personal injury.
4.3. Connect the transformer plug to the mains power supply and switch the internal cabinet light on.
Turn the air supply on, (having first adjusted to between 60 and 120psi). If attached, start the dust extraction unit. If no extraction
unit remove the air flow cover from rear (fig 4.Z).
4.4. 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 mover your hand and grasp objects correctly.
4.5 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.
4.6 Hold the work piece with the other glove. Hold and move the workpiece to ensure you keep glove and fingers out of the nozzle blast
stream. DO NOT aim the blast at your fingers, gloves or internal light.
4.7 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 lesser airflow.
4.8 To open 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.
4.9 When work is complete, disconnect gun from the air line, unplug from the mains electrical supply and switch off dust extraction if fitted.
5. MAINTENANCE
pWARNING! 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 becomes excessively dusty, loses its granular or spherical appearance, or debris from workpieces mixes 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 to perform this task.
5.5. If used, regularly check that the exhaust vent at the back of the cabinet (fig 4.Z) is clear and not blocked.
If you use an extraction unit change the filters according to use.
5.6. Regularly check gun blast nozzle to ensure it does not become blocked with media. Immediately replace worn or damaged nozzles.
5.7. If abrasive pick-up hose becomes blocked, re-power the unit, ensure the doors are correctly closed. Cover the gun tip and 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 dust free light tube not greater than 70 Watts.
