Overall, it’s good news. You can use a lawn mower and other power tools with a pacemaker, but not chainsaws:
Can I use a chainsaw?
Chainsaws are hard to operate at a safe distance from your chest pacemaker. They should be avoided altogether.
Hard to argue with the factual assertion. The user would either: (1) have to rip the pacemaker out of his chest and leave it in the house; (2) set the chainsaw up in the backyard, start it, and run like hell; or (3) tap in to Rubber Man’s secret.
