Cutterless Chain for Service
 For any chain saw, to properly tune the carb or verify running 
RPM at idle and wide open throttle a bar and chain should be 
installed
 Cutterless chains are available to provide a safe way for the 
service technician to do this without fear of the chain coming 
into contact with anything

All Current Models of STIHL Chain Saws are Equipped with 
the STIHL Quickstop® Chain Braking System
The chain is stopped and locked when the hand guard is 
pushed toward the guide bar nose by the left hand – or when 
the brake is activated by enough inertia in certain kickback 
situations
