4 Working Techniques

– Always work with water and wet cutting when
using diamond abrasive cutting wheels
– Depending on the version, resin abrasive cut‐
ting wheels are suitable only for dry cutting or
only for wet cutting. Always use wet cutting
with composite resin abrasive cutting wheels
that are suitable only for wet cutting
3.2 Pulling away
The cut-off machine pulls forward, away from the
user, when the abrasive cutting wheel touches
the object to be cut from above.
4 Working Techniques
4.1 Cutting
Work calmly and carefully – in daylight conditions
and only when visibility is good. Do not endanger
others – stay alert at all times.
The abrasive wheel must be guided
straight in the cut, without wedging.
Never exert lateral pressure on the
abrasive wheel.
Do not use for lateral grinding or
scrubbing.
Do not stand in line with the abrasive wheel.
Ensure sufficient freedom of movement, espe‐
cially in construction trenches there must be suf‐
ficient space for the user and for the part being
cut to fall.

Do not lean too far forwards and never bend over
the abrasive wheel.
Don not work while standing on a ladder – not at
unstable places – not over your shoulder height –
not with one hand only – risk of accident!
The cut-off machine may only be used for cut‐
ting. It must not be used as a lever or shovel.
Do not press down on the cut-off machine
Always decide the cutting direction before posi‐
tioning the cut-off machine. Do not change the
cutting direction. Avoid knocks and bumps with
the cut-off machine while in the cut – do not drop
the machine into the cut – danger of breakage!
Diamond abrasive wheels: If cutting performance
begins to deteriorate, check the sharpness of the
diamond abrasive wheel, resharpen as needed.
To do this, briefly cut through abrasive material,
e. g., sandstone, aerated concrete or asphalt.
At the end of the cut, the cut-off machine is no
longer supported by the abrasive wheel in the
cut. The user has to absorb the weight force –
risk of loss of control!
When cutting steel: glowing metal
particles may cause fires!
Keep water and sludge away from alive electrical
cables – risk of electric shock!
Drag the abrasive wheel into the workpiece – do
not push it into the material. Do not correct
severing cuts with the cut-off machine. Do not re-
cut – remove left webs or breaking edges (for
example, with a hammer).
When applying diamond-coated abrasive wheels,
take a wet cut.
Depending on the version, resin abrasive wheels
are only suitable for dry cutting or only for wet
cutting.
When using abrasive wheels made from syn‐
thetic resin, which are suited for wet cuts only,
take such wet cuts only.
When using abrasive wheels made from syn‐
thetic resin, which are suited for dry cuts only,
take such dry cuts only. If however composite
resin abrasive wheels of this type become wet,
their cutting performance is reduced and they
become dull. If composite resin abrasive wheels
of this type become wet while working (e. g., due
to puddles or water in pipes), do not increase the
cutting pressure, but continue working with the
