SMC Filter/Regulator - How to Drain the Bowl of Moisture

When using the SMC Filter/Regulator with the NSK Presto High Speed Engraving handpiece, you will want to keep an eye on the moisture that will gather in the bowl of the Filter/Regulator and drain the bowl regularly to avoid moisture reaching your engraving equipment.
The amount of moisture will vary based on your location, temperature and the humidity in your environment.
To Drain the moisture, simply turn the plastic drain knob on the bottom of the regulator bowl counter-clockwise. You will only need to turn it about 1/4 turn. After draining, turn the knob clockwise, only finger tight to seal the drain and return to your engraving.
