Be sure to calibrate your gage to the correct specs! Start by dressing your wheel to 3/8”. When you have done this, you’re to clean your table top of all debris. Once completed, you’re to set the height comparator gage in front of the finishing head and slowly move it so that the two bearings are cradling both sides of the wheel. Now lock the magnet in place. Once locked into place loosen the bezel clamp and begin turning the face of the bezel until you have reached the zero (0) indicator. Retighten the bezel clamp. Now that the gage is calibrated, you need to adjust your skate holder. Lock the gage to the table top where it is clear of everything. With your skate in its holder, you’re to touch the heel of your blade to the gage’s bearings. Adjust the holder until your bezel reads zero (0). Do the same of the toe of your skate. Once both sides of your skate reads zero (0), your skate holder has been centered and you are ready to sharpen.
