Sister Margaret Ann says she had to use Google to find out how to start the saw because she'd forgotten how.
The nun, who is principal of Archbishop Coleman F. Carroll High School in Miami, says several people have sent her videos on how to use a chainsaw correctly after watching her online.
Sister Margaret Ann laughed off the attention, saying her students are enjoying watching her on social media. Some have even asked for her autograph.
She also said she was glad the video gave the public a different view of nuns.
