For the past ten years the HSE has had concerns over the safety of the use of top-handled chainsaws. These chainsaws are of a fundamentally different design to conventional chainsaws in that the rear handle is positioned on the top of the machine. This allows the chainsaw to be used one-handed. It is the expressed opinion of the HSE that this design ignores one of the fundamental design aspects of conventional chainsaws, namely that they should be held with both hands when being operated. One-handed use can result in the operator having less control over the chainsaw. In one-handed use the saw may skate, bounce or kick back on contact with the material being cut, or may come into contact with the operator's free hand/arm if used incorrectly.
