7.Now rotate the bearing guide shafts until the bearings are approximately 1⁄64'' from the blade. Hold the shafts in place with a screw driver and tighten the bearing guide lock nuts. The guide bearing, when adjusted cor- rectly, should have a slight drag against the blade. If the guide bearings pinch the blade, it will damage the bearing guides and blade.
8.Slide the rear support bearing until it is approximately 1⁄32'' from the blade and tight- en.
The bearing guide shaft lock nuts should only be as loose as necessary to allow the shafts to rotate. If they are too loose it will be very difficult, if not impossible, to adjust the guides accurately.
