7 Kickback and Other Reactive Forces
Quickstop chain brake will reduce this protection and also
disable the chain brake, increasing the risk of kickback
injury.
– Never operate your chain saw without a properly
functioning front hand guard.
– Never attempt to remove, modify or disable the front
hand guard or any other component of the chain
brake.
￭ No Quickstop or other chain brake device prevents
kickback. These devices are designed to reduce the risk
of injury, if activated, in certain kickback situations. To
reduce the risk of severe personal injury or death from
kickback:
– Always follow the instructions in this manual and
follow good working technique. For example,
position your body clear of the cutting attachment
whenever the motor is running. Stand to the left of
the cut while bucking, outside of the cutting plane,
see chapter "Holding and Controlling the Chain
Saw", @ 6.5.2.
– Maintain as much distance as possible, and never
less than 45 degrees, between the bar and your
body to ensure that the Quickstop has sufficient time
to activate and stop the saw chain before reaching
any part of your body.
– Follow the other precautions provided in chapter
@ 8.
￭ An improperly maintained chain brake may increase the
time needed to stop the saw chain after activation, or may
not activate at all. For the Quickstop to reduce the risk of
kickback injury, it must be properly maintained and in
good working order.
– Read and follow the instructions on engaging and
disengaging the chain brake, @ 16.1, and
maintaining and repairing it, @ 16.3.
2. Low Kickback Saw Chain and Reduced Kickback Bars
STIHL offers a variety of guide bars and saw chains. STIHL
reduced kickback bars and low kickback saw chains are
designed to reduce the risk of kickback injury. Other saw
chains are designed to achieve higher cutting performance
0458-716-8621-D
or sharpening ease, but are more prone to kickback and may
kick back with more energy, making it more difficult to
control the chain saw.
STIHL has developed a color code system to help you
identify the STIHL reduced kickback bars and low kickback
saw chains.
– Cutting attachments with green labels on the packaging
are designed to reduce the risk of kickback injury.
– Matching green-marked or labeled chain saws with green-
labeled bars and green-labeled saw chains provides
compliance with the computed kickback angle
requirements of the chain saw standards when the
products are in their original condition.
– Products with yellow labels are for users with
extraordinary cutting needs, having experience and
specialized training for dealing with kickback.
STIHL recommends the use of its green-labeled reduced
kickback bars, green-labeled low kickback saw chains and a
chain saw equipped with a STIHL Quickstop chain brake for
both experienced and inexperienced chain saw users.
STIHL recommends green-labeled bars and chains for all
chain saws. See your "STIHL Bar and Chain Information"
leaflet for details.
New bar and chain combinations may be developed after
publication of this literature, which will, in combination with
certain electric chain saws, comply with the chain saw
standards as well.
WARNING
￭ Use of bar and saw chain combinations not listed in the
STIHL Bar and Chain Information leaflet (or other
combinations that do not comply with the chain saw
