Using the Lenox LXAH9912PBM arbor is a breeze. First, make sure the collar is in the locked position. To change the saw or the pilot bit, use the two - step Snap - Back® release. Start by unlocking the hole saw in step one, then unlock the pilot bit in step two. This can all be done without an Allen key. When drilling, you can operate it with one hand as the collar snaps back and stays in place. Just remember, this arbor is only compatible with Lenox Pilot Drills and all threaded hole saws within the diameter range listed on the packaging. For maintenance, after each use, clean the arbor with a dry cloth to remove any debris. Store it in a dry place to prevent rusting. Avoid using excessive force when changing bits to keep the anti - jam collar in good condition.
