摘要
A safety system for a chainsaw has a brake lever (14) mounted in front of the support grip (13) to activate the safety brake (11) if the operator's hand slips off the grip towards the saw blade, or if the brake lever strikes an obstruction. The brake release linkage (12) has an initial reaction force, to trip the brake, and a second, larger reaction force to hold the brake lever and prevent is jamming onto the fingers on the handgrip.
