Product Description
?This is an authentic Husqvarna part which is supplied by the original equipment manufacturer for use with chainsaws. The throttle lockout must be depressed in order to trigger the equipment. It is used as a safety device to prevent accidental activation of the chainsaw. If the part is missing or is damaged, this will provide an identical replacement for the original component that was installed on a new unit. One durable plastic throttle lockout is included. Note, a screwdriver will be needed to perform this repair.
