6. 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.
6.1.
Check all fittings to ensure there are no air leaks.
6.2.
Pour the abrasive media into the centre of the cabinet. DO NOT use more than 10lbs (4.5kg). Excessive amounts of abrasive will
impair visibility, create poor blasting performance and could block the air exhaust.
6.3.
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.
6.4.
Plug the transformer into mains socket and transformer lead plug into light switch box and the unit is ready for use.
6.5.
Place the workpiece in the cabinet and close and latch the lid securely.
6.6.
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.
WARNING! Failure to securely close the lid could result in damage and/or personal injury.
‰
6.7.
Turn on light and air supply and insert hands into cabinet gloves. Grasp gun and depress the trigger to start the blasting process.
6.8.
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.
