Reducing the Risk of Kickback Injury
Warning!
To reduce the risk of kickback injury,
avoid cutting with the upper quadrant of
the wheel where possible. Be especially
cautious for a pinching or binding of the
wheel in this area, which can cause
severe reactive forces in a rotational
kickback motion.
Be alert to potential movement of the
workpiece or anything else that could
cause the cut to close and pinch the
wheel. In order to reduce the risk of
TS 700, TS 800
pinching, support the workpiece in such
a way that the cut remains open during
the cutting process and when the cut is
finished (see illustration.) Never make a
cut that results in a binding of the wheel.
If you cannot properly support the
workpiece, do not use a cutting-off
machine to make the cut; select another
tool or cutting technique that is not
subject to kickback.
Warning!
Be particularly alert when cutting a
workpiece such as a pipe with a belled
end or a pipe in a trench that, if not prop-
erly supported, can sag upon
completion of the cut, creating a pinch
not where you are actually cutting but,
rather, at or near the top of the work-
piece. If the pinch is in the upper
quadrant of the abrasive wheel, kick-
back can result.
Warning!
Use wet-cutting whenever feasible,
since the water can act as a lubricant in
a pinch situation and thus reduce the
likelihood of reactive forces occurring
and the energy of any such forces that
do occur, making it easier to maintain
control of the machine.
Warning!
Use only cutting attachments author-
ized by STIHL. Use of non-STIHL-
authorized wheels may be extremely
dangerous. Many substandard diamond
wheels, for instance, are available in the
market. If they are not manufactured
with the proper quality steel in their core,
if they are not properly tensioned, or if
other design or manufacturing defects
exist, they may, e.g., begin to wobble
during use. If a diamond wheel begins
or ceases to wobble within the kerf, the
change in the behavior of the wheel may
cause a severe binding that can lead to
loss of control and / or kickback. If the
wheel you are using begins to wobble or
has ever wobbled, discard it immedi-
ately. Although such a wheel may
temporarily cease to wobble, e.g., if run
without load, it will always be prone to
wobble again under certain conditions.
Some other unauthorized diamond
wheels are manufactured with abrasive
material on their sides. Do not use such
wheels, since the abrasive material may
lead to increased reactive forces in a
pinch situation.
