7 Kickback and Other Reactive Forces
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
0458-716-8621-C
standards) may increase kickback forces as well as the
propensity for kickback and increase the risk of kickback
injury.
– Please ask your authorized STIHL servicing dealer
to properly match your chain saw with the
appropriate bar and saw chain combination to
reduce the risk of kickback injury.
￭ Reduced kickback bars and low kickback saw chains do
not prevent kickback, but they are designed to reduce the
risk of kickback injury.
– STIHL recommends green-labeled bars and green-
labeled saw chains for all chain saws and all users.
￭ Even if your saw is equipped with Quickstop, a reduced
kickback bar and/or low kickback saw chain, this does not
eliminate the risk of injury from kickback.
– Observe all safety precautions discussed in this
manual to avoid kickback situations.
a. Low Kickback Saw Chain
Some types of saw chain have specially designed
components to reduce the propensity for kickback and the
force of kickback if it occurs. STIHL has developed low
kickback saw chain for your chain saw.
A "low kickback saw chain" is a saw chain that has met the
kickback performance requirements of ANSI/OPEI B175.1
(for Canada: CSA Z62.3) when tested according to the
provisions specified in ANSI/OPEI B175.1 (for Canada:
CSA Z62.3).
WARNING
￭ Some low kickback saw chains have not been tested with
all chain saw and bar combinations. There are potential
chain saw and bar combinations with which low kickback
saw chains can be used which have not been specifically
certified to comply with the 45° computer-derived kickback
angle of the chain saw standards.
– STIHL recommends green-labeled bars and green-
labeled saw chains for all chain saws and all users.
– Please see your STIHL Bar and Chain Information
leaflet for the appropriate bar/saw chain
combination.
