a. Low Kickback Saw Chain
Some types of chain have specially designed
components to reduce the propensity for kick‐
back and the force of kickback if it occurs. STIHL
has developed low kickback chain for your chain
saw.
A "low kickback chain" is a chain that has met
the kickback performance requirements of
CSA Z62.3 when tested according to the provi‐
sions specified in CSA Z62.3.
WARNING
■ Some low kickback chains have not been tes‐
ted with all chain saw and bar combinations.
There are potential saw, bar and low kickback
chain combinations which have not been spe‐
cifically certified to comply with the 45° com‐
puter-derived kickback angle of the chain saw
standards.
► STIHL recommends green-labeled bars and
green-labeled chains for all chain saws and
all users.
► Please see your STIHL Bar and Chain
Information leaflet for the appropriate bar
and chain combinations for your saw.
► If you are unsure which bar and chain com‐
bination to select, ask your authorized
STIHL servicing dealer to properly match
your chain saw with the appropriate bar and
chain combination to reduce the risk of kick‐
back injury.
■ A blunt or incorrectly sharpened chain may
reduce or negate the effectiveness of design
features intended to reduce kickback energy
and the propensity for kickback. Improper low‐
ering or sharpening of the depth gauges or
changing the shape of the cutters may
increase the risk and the energy of kickback.
► Always cut with a properly sharpened
chain.
► Read and follow the instructions on sharp‐
ening a chain,
■ Any chain saw mounted with a bow guide is
potentially very dangerous. The risk of kick‐
back is increased with a bow guide because of
the increased kickback contact area and
because the design of bow guides places the
upper portion of the bar closer to the opera‐
tor's body. Using a low kickback chain will not
significantly reduce the risk of kickback injury
when used on a bow guide.
► Never mount a bow guide on any STIHL
chain saw.
b. Reduced Kickback Bars

24.4.
6 Kickback and Other Reactive Forces
STIHL green-labeled reduced kickback bars are
designed to reduce the risk of kickback injury
when used with STIHL green-labeled low kick‐
back chains.
WARNING
■ When used with other, more aggressive
chains, green‑labeled reduced kickback bars
may be less effective in reducing kickback.
► STIHL recommends green-labeled bars and
green-labeled chains for all chain saws and
all users.
■ For proper balance and to comply with the
chain saw standards:
► Use only bar lengths listed in this manual,

6.2.4 To Avoid Kickback
The best protection from personal injury that may
result from kickback is to avoid kickback situa‐
tions:
1) Hold the chain saw firmly and with both
hands and maintain a secure grip, with your
right hand on the rear handle and left hand
on the front handle. Maintain a secure grip
with thumbs and fingers encircling the chain
saw handles. Don't let go.
2) Make sure the area in which you are cutting
is free from obstructions.
3) Be aware of the location of the guide bar
nose at all times. Never let the nose of the
guide bar unintentionally contact any object.
Do not cut limbs with the nose of the guide
bar. Be especially careful near wire fences
and when cutting small, tough limbs, small
size brush and saplings which may easily
catch the saw chain.
4) Do not overreach.
5) Do not cut above shoulder height.
6) Begin cutting and continue at full speed.
7) Cut only one log at a time.
8) Use extreme caution when re-entering a pre‐
vious cut.
9) Do not attempt to plunge cut if you are not
experienced with this cutting technique.
10) Be alert for shifting of the log or other forces
that may cause the cut to close and pinch
the saw chain.
11) Maintain saw chain properly. Cut with a cor‐
rectly sharpened, properly tensioned saw
chain at all times.
