STIHL has issued a recall to repair certain STIHL TS 410 and TS 420 cut-off machines that were manufactured between January 2021 and April 2021.

STIHL has learned that a limited number of TS 410 and TS 420 cut-off machines (see noted serial number range, below) were assembled with the flywheel-to-crankshaft connection overtightened. Overtightening of this connection may damage the flywheel, which could cause the flywheel to fail and break apart while the engine is running.

A failure during the operation of the machine would pose a projectile hazard to the user and to bystanders. A damaged flywheel is not apparent from a visual inspection.

Affected serial number range: 189442634 - 190001700

If you own a STIHL TS 410 or TS 420 cut-off machine in the given serial number range, please discontinue using the machine immediately and contact your local STIHL dealer for a free repair.

If you have any questions, please do not hesitate to contact your local STIHL dealer or contact STIHL Incorporated at: 800-233-4729.
