4.2.4.
Remove blanking plug from rear panel arrow "A" Fig.2.
4.2.5.
Fit screen (23) into cabinet with angled corner to rear right hand side, to allow suction hose (14) through.
5. OpERATION
WARNING! Ensure you read, understand and apply safety instructions in Section 1 before using the unit.
‰
NOTE!
We strongly recommend that a suitable dust extraction system is used with this unit.
If dust extraction is not used, media may be forced out of the joints as pressure builds up. you can alleviate this to some
extent by removing the white blanking plug (fig.2) situated on the upper left corner at the rear of the tank when viewed
from the front. This however, will not substitute for a suitable dust extraction system.
5.1.
Connect the air supply to the inlet on the side of the cabinet. Ensure the gun valve is in the "off" position before connecting the air
supply.
5.2.
Check all fittings to ensure there are no air leaks.
Pour the abrasive media into the centre of the cabinet. DO NOT use more than 10lbs (4.5kg). excessive amounts of abrasive will
5.3.
impair visibility, create poor blasting performance and could block the air exhaust.
5.4.
The unit is supplied with four ceramic nozzles being 4, 5, 6, & 7mm hole diameter respectively. The choice of nozzle depends on the
size of the blasting media. Coarse media should be used with the larger nozzles, fine media should be used with the smaller
nozzles. To fit a new nozzle, unscrew the nozzle retaining ring, remove the existing nozzle and replace with the new one.
5.5.
Plug the transformer into mains socket and transformer lead plug into light switch box and the unit is ready for use.
5.6.
Place the workpiece in the cabinet and close and latch the lid securely.
WARNING! failure to securely close the lid could result in damage and/or personal injury.
‰
5.7.
Turn on light and air supply and insert hands into cabinet gloves. Grasp gun and depress the trigger to start the blasting process.
5.8.
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 surface 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.

6. MAINTENANCE
WARNING! Ensure the cabinet is disconnected from the electrical mains and the air supply before attempting any
‰
maintenance.
6.1.
Ensure the blasting media does not become damp. Keep the air supply dry at all times. Dispose of any damp media.
6.2.
Replace media when it has become excessively dusty, loses its granular or spherical appearance, or is significantly contaminated
with debris from workpieces. This is usually noticed when media from the nozzle looks like a smoke cloud rather than steam.
6.3.
Regularly check that the exhaust vents at the side and rear of the cabinet are clear.
6.4.
Regularly check gun blast nozzle to ensure it does not become blocked with media. Immediately replace worn or damaged nozzle.
6.5.
If abrasive pick-up hose becomes blocked, cover the gun tip to force air back through the hose. Ensure the lid is correctly closed.
6.6.
Replace the transparent protective sheet on the underside of the Perspex window when visibility becomes reduced.
