Australia's former world Number one posted a photo to Instagram of himself lying in a hospital bed with his left arm heavily bandaged.
Norman, 59, issued a warning alongside the photo and suggested he had come close to severing one of his hands.
"Working with a chainsaw ALWAYS be respectful of the unexpected. I was one lucky man today. Damaged, but not down & out. Still have left hand," Norman tweeted.
Norman last week posted a photo of himself working with a chainsaw to cut back a small tree at what appears to be one of his seaside properties.

Norman inspired many current day Australian professionals to play golf, including world No.2 Adam Scott.
Scott paid tribute to the two-time major winner after becoming the first Australian to capture the Masters at Augusta last year.
"Part of this is for him (Norman) because he's given me so much time and inspiration and belief," Scott said at the time.
Norman's mishap invoked memories of a near-fatal accident to fellow Australian and former British Open and Augusta Masters runner-up Jack Newton.
He lost his right arm and eye and sustained severe abdominal injuries.
Newton spent several days in a coma and eight weeks in intensive care before a prolonged rehabilitation from his injuries to return to public life as a television and radio golf commentator.
