Installation
(cont’d)
4. Using a 4" diameter flexible duct and 2 hose clamps (usually provided with the dust
collector) connect the workstation to a dust collection unit.
5. Follow the instructions in sections 2 and 3 of this manual to prepare for blasting.
CAUTION:
The air that comes out of the nozzle contains abrasive. Do
not point the nozzle at anything that could be harmed or damaged as a
result of abrasive flow.
6. With the Power switch on the rear of the workstation turned OFF, connect the power
cord to the AC voltage outlet.
7. Turn the Power switch to the ON position. The lamps in the workstation should light.
Operation
1. Micro-abrasive blasting operations should be conducted according to the instructions
in sections 2 and 3 of this manual.
CAUTION:
Never point the nozzle in the direction of the glass window.
The abrasive stream will etch the glass, reducing operator visibility and
requiring premature replacement of the workstation window.
2. Turn the Power OFF when the workstation is not in use.
