Chain Brake

The chain brake system on your saw
has two functions:
N Standard STIHL Quickstop chain
brake and
N
STIHL Quickstop Plus chain brake
system
The standard STIHL Quickstop chain
brake utilizes the front hand guard as the
activating mechanism and is designed to
stop the chain within fractions of a
second. The STIHL Quickstop Plus
chain brake system, on the other hand,
is designed to stop chain rotation within
a second of the operator fully releasing
the rear handle.
To reduce the risk of personal injury or
property damage during cutting,
observe the characteristics that make
this saw different from saws not
equipped with a rear-handle-activated
STIHL Quickstop Plus chain brake
system. Before operating the chain saw
for the first time, make sure you are
familiar with how the STIHL Quickstop
Plus chain brake system works.
