To reduce the risk of injury from blade contact, circular saw blades may be used on FS brushcutters that have a limitstop, a bicycle handle and double shoulder harness and not on FS brushcutters with a "J" handle or loop handle.

To reduce the risk of eye injury always wear proper eye protection. Always use the appropriate deflector for the type of cutting attachment, as explained in your instruction manual.

Reviews

FS 91 R is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great Brushcutter! So I purchased this for a new property in foreclosure, lots and lots of brush to clear, and blackberry bushes. The 1's are the new models of the 0's, meaning 91 is the new 90 so on so forth. I was considering the 91, 111, 131. I went with the 91 because wanted to buy a chainsaw too. SO happy with the 91! no shortage of power. All I have done is attach the 4 edge blade on it and it cuts right thru all the brush and bushes.
