STIHL Quickstop and Quickstop Plus are braking features found on STIHL chainsaws that allow the chain brake to be activated manually or by sufficient kickback force.
Quickstop is a common feature found on all STIHL chainsaw models. Quickstop is part of the front hand guard, which protects the operator’s hand from the chain and debris. When pushed forward, the chain brake activates, stopping the chain in a split second.
STIHL Quickstop Plus is an additional braking feature found on select STIHL chainsaw models. This features allows the chain brake to be manually activated from the rear handle. Whenever the operator releases the rear handle, the chain brake engages. Chainsaws with Quickstop Plus are indicated by the letter “Q” in the model name.
