12.3 Maintaining the Chain Brake

WARNING
An improperly maintained chain brake may increase the time
needed to stop the saw chain after activation, or it may not
activate or stop the chain at all, @ 6.2. The chain brake is
subject to wear, depending on the amount of usage,
conditions under which the saw is used and other factors.
Excessive wear will reduce the effectiveness of the chain
brake and can render it inoperable.
► Your chain saw should be returned to your authorized
STIHL servicing dealer for periodic inspection and
servicing of the brake system according to the following
schedule:
– Heavy Usage: every 3 months
– Part-Time Usage: every 6 months
– Occasional Usage: every 12 months
