Never wear loose fitting clothing or a tie which can be caught to the rotating part.

SAFETY EQUIPMENT Be sure to keep a first aid kit and fire extinguisher han- dy at all times. E. CLEAN WORKING AREA Keep the working area clean before and during work. If any oil or fuel is spilled, it should be cleaned up immedi- ately.
