substantially increase the risk of
personal injury or death from reactive
forces, thrown segments or loss of
control. If a diamond cutting wheel
begins or ceases to wobble within the
cut, 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 immediately. Although such a
wheel may temporarily cease to wobble,
e.g., if run without load, it will always be
prone to wobble again. A wheel that
wobbles is extremely dangerous.
WARNING
Some non-STIHL branded diamond
cutting wheels are manufactured with
abrasive material on their sides. Do not
use such wheels, since the abrasive
material increases frictional forces and
will lead to substantially increased
reactive forces in a pinch or side loading
situation.
WARNING
Never use chipped abrasive cutting
wheels, wheels with missing or
damaged segments, or circular saw
blades, carbide-tipped blades, rescue
blades or wood-cutting or toothed
blades of any nature on a cut-off
machine. The use of such wheels or
blades will greatly increase the risk of
loss of control and severe personal
injury or death from reactive forces,
since the chipped or damaged section of
an abrasive cutting wheel or the teeth of
a saw blade may catch in the material
18
being cut and generate substantially
greater reactive forces, including
rotational kickback.
Cut-off machines are designed for use
with abrasive cutting wheels in good
condition only. Machines designed for
use with wood-cutting or other toothed
blades use different types of guarding
systems that provide the protection
necessary for those types of blades.
Machines, such as a cut-off machine,
that are designed for use with abrasive
cutting wheels require a different
guarding system, which is not designed
to provide protection against all dangers
presented by circular saw blades,
carbide-tipped blades, rescue blades or
wood-cutting or toothed blades of any
nature.
WARNING
To reduce the risk of injury from loss of
control from reactive forces, including
kickback, when cutting:
1. Hold the cut-off machine firmly with
both hands, left hand on the front
handle, right hand on the rear
handle.
2. Maintain good balance and footing
at all times. Never cut while
standing on a ladder or other
unsecure platform.
3. Position the cut-off machine in such
a way that your body is clear of the
cutting attachment and outside the
plane of the cutting attachment.
That means the operator must avoid
standing in direct line with the wheel
(see illustration). Never bend over
the cutting attachment or position
your head and upper body forward
of the front handle, especially when
the guard is pulled back exposing
the top of the wheel. Always
maintain at least a 45° angle
between the top of an exposed
wheel and the operator's head,
neck and body. Ensure sufficient
freedom of movement, especially in
trenches. Make sure there is
sufficient space for the user and the
fall of the severed portion of the
workpiece.
4. STIHL recommends using only
STIHL branded abrasive cutting
wheels properly rated for the
material to be cut.
5. Never use circular saw blades,
carbide-tipped blades or toothed
blades of any nature. Their use
increases the risk of injury from
blade contact, thrown tips and
reactive forces, including kickback.
