| Re: Oster small animal A5 clipper question O.K. you need to have them running to snap the blades on correctly. Slide the blade onto the silver tongue on the clippers and with some pressure, snap it down. When the blade has been locked on it will not vibrate off. The black post is called a lever, it goes into the square hole in the blade to move the cutter blade back and forth. Let me know if it works. |
