<p>A chainsaw (100) including a tool body (202), a power unit housed within the tool body (202) and configured to operate at least in part in response to actuation of a trigger (136), a working assembly (122) powered responsive to operation of the power unit via a clutch, a clutch cover (220) that is removable from the tool body (202) to enable access to the clutch, and a brake assembly configured to slow the working assembly (122) responsive to release of the trigger (136). The brake assembly includes a first brake member (200) arranged in the tool body (202), and a second brake member (210) arranged in the clutch cover (220). The second brake member (210) is biased toward engagement with the first brake member (200) to slow the working assembly (122) when the trigger (136) is not actuated. The second brake member (210) is operably coupled to the trigger (136) via a first force transmitting member (160) disposed in the tool body (202) and a second force transmitting member (240) disposed in the clutch cover (220). The first and second force transmitting members (260, 240) are operably coupled to each other via a cover release operator (250) such that the cover release operator (250) includes a cover detachment position in which the first and second force transmitting members (260, 240) are enabled to be uncoupled for removal of the clutch cover (220) from the tool body (202).</p> |
