Fits Husqvarna 340 345 346 350 353 357 359

This throttle trigger lockout kit replaces OEM parts 503854501 and 503854401 on the listed Husqvarna chainsaw models. It restores the safety interlock that prevents accidental throttle engagement. The kit suits owners and technicians servicing these specific two-stroke saws.

Direct OEM replacement parts

The kit includes one throttle trigger and one lockout lever moulded to match the original dimensions. Installation uses the existing mounting points on the chainsaw handle, so no modification is required. The components are made for petrol-powered, single-cylinder engines.

Two-piece kit restores full function

Supplying both trigger and lockout together ensures the mating surfaces wear evenly from the start. This avoids the premature failure that can occur when only one half is replaced. The parts are ready to fit straight from the package.
