ricochet. Failure to follow this instruction
could result in serious or fatal injury.
The ideal working speed of the cut-off
machine depends on many factors, e. g.,
the material being cut, the type and
quality of the cutting wheel.
It is essential to determine the direction
of the cut exactly before applying the
abrasive wheel to the work. Wheels are
constructed for
UDGLDO
pressure only.
/DWHUDO
pressure must be avoided.
Check for cracks and make sure that no
pieces have broken off from the wheel
when it is stopped.
Check the wheel guard for cracks. If you
discover any cracks, fit a new guard.

Hold the cut-off machine steady. Do not
change the direction of the cut during
the cut as this may produce a high
torsional load on the abrasive wheel and
may cause it to break or shatter.
To achieve a clean and efficient cut, pull
the abrasive wheel across the work or
move it "to and fro" in the cutting
direction. Do not use force to push the
abrasive wheel into the work.
Insert the wheel into the material only as
deep as necessary to make the cut.
To reduce the amount of dust created,
do not cut all the way through stone and
concrete materials - leave a thin piece
uncut. For most such materials, this
piece can be easily broken afterwards.
Do not cock, jam or wedge the wheel in
the cut.
:DUQLQJ
Do not use abrasive wheels for rough
grinding. Large bending stresses occur
during such work and abrasive wheels
may shatter or break and could cause
serious or fatal injury.
If a cut-off machine cart is used, sweep
debris from the path of the wheels as
such may cause flexing of the abrasive
wheel. This would result in high frictional
forces and thus greatly reduce the
engine power available for the actual
cutting work.
Always use the cart to cut in a straight
line.

When cutting masonry with a water
attachment:
1.
Make certain water does not flow on
wheel that is not running, since the
wheel will absorb water and that will
affect wheel balance.
2.
Shut water off before wheel stops
so that excess water will be
dissipated.
3.
Be certain water is applied to both
sides of wheel, since uneven
distribution can cause "one sided"
wear with possible wheel breakage.
4.
Use these wheels up the same day.
Do not store and reuse a wheel that
has been used with water.

At correct idle speed, wheel should not
turn. For direction to adjust idle speed,
see the appropriate section of your
owner’s manual.
Do not use a cut-off machine with incor-
rect idle speed adjustment. The rotating
wheel may cause injury.
Have your STIHL dealer check your
cut-off machine and make proper
adjustments or repairs.
Never touch a rotating wheel with your
hand or any part of your body.

Reactive forces may occur at any time
the cutting wheel on at cut-off machine
is rotating. If the wheel is slowed or
stopped by frictional contact with any
solid object or by a pinch, reactive forces
may occur instantly and with great force.
