Working safely with cut-off machines

Operating Instructions
1.
Do not exceed the maximum
operating speed marked on the
wheel.
2.
Do not use a wheel that has been
dropped.
3.
Test each new wheel immediately
after installation for approximately
one minute at maximum speed
without cutting, making sure to keep
bystanders away.
4.
Do not cut any material for which the
abrasive wheel is not authorized.
5.
Do not grind on the side of the
abrasive wheel.
6.
Do not twist, thrust, knock or drop
the machine. This can cause
damage to the wheel.
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.
Always stop the engine and be sure the
wheel has stopped rotating before
setting down the cut-off machine.
If a cut-off machine cart is used, sweep
debris from the path of the wheels, as
debris under one of the cart’s wheels
may cause flexing of the abrasive wheel.
This could result in high frictional forces
and thus greatly reduce the engine
Warning!
To reduce the risk of injury from fire, do
not cut into any pipe, drum or other con-
tainer without first ensuring that it does
not contain a volatile or flammable
substance.
Warning!
When cutting into existing walls, floors
or similar structures, be alert for hidden
hazards such as electrical cables, water
and gas pipes and flammable sub-
stances. Make sure that power, water
and gas have been shut off and pipes
drained before starting to cut.
Warning!
The wheel guard is adjustable. It is
extremely important that the wheel
guard is in place and set to suit the type
of work and your stance. The guard
should always be adjusted so that the
user is not endangered by particles of
the material being cut, sparks or pieces
of damaged wheels either directly or by
ricochet. Failure to follow this instruction
could result in serious or fatal injury.
Warning!
Your cut-off machine is equipped with a
wheel guard limit stop that restricts the
opening of the wheel guard. To reduce
the risk of injury from wheel contact and
/ or reactive forces and to avoid damag-
ing the guarding system, never attempt
to pull the adjusting lever past the limit
stop.
Warning!
Always check the wheel before use and
after unintentionally striking any object;
frequently check it during use when it is
stopped. Look for cracks and make sure
that it is undamaged and in good condi-
tion and that no pieces have broken off.
See sections on "Abrasive Wheels" and
"Reactive Forces" in this manual. Check
the wheel guard for cracks. If you dis-
cover any breaks or cracks, fit a new
guard before further use.
Warning!
It is essential to determine the exact
direction of the cut before applying the
abrasive wheel to the work. Wheels are
constructed for
radial
pressure only.
Lateral
pressure must be avoided. Hold
the cut-off machine steady. To reduce
the risk of serious or fatal injury, do not
change the direction of the cut during
the cut as this may produce a high tor-
sional load on the abrasive wheel and
may cause it to break or shatter.
Warning!
Do not use abrasive wheels for rough
grinding. Large bending stresses occur
during such work, which may cause
abrasive wheels to shatter or break and
result in serious or fatal injury.
Warning!

tered abrasive wheels:
