2.2 Hall Bur Guard Assembly Instructions
WARNINGS:
1. Do not operate the drill without the appropriate bur guard.
Always use a bur of the proper length. The tip of the bur
guard should cover the safe line on the bur, if applicable.
Without the stabilization that the proper guard provides,
the bur can break and be propelled with great force.
2. To reduce the risk of injury, prior to surgery, spin the bur
guard on a bur. If the bur guard spins freely, the bearing is
still good. Otherwise, the bur guard must be sent for repair
immediately. DO NOT USE.
