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
42
same pressure – risk of breakage! Use up such
composite resin abrasive wheels immediately.
5 Sample Applications
5.1 Water attachment
– Water attachment on the cut-off machine for
all types of water supplies
– Pressurized water tank 10 l for binding dust
Use clean water for binding dust.
5.2 Water must always be used for
wet cutting when working with
diamond abrasive cutting
wheels
5.2.1 Extend service life and increase cut‐
ting speed
Always ensure a supply of water to the abrasive
cutting wheel.
5.2.2 Binding dust
The abrasive cutting wheel must be supplied with
at least 0.6 liters of water per minute.
5.3 Use composite resin abrasive
cutting wheels with or without
water – depending on version
Depending on the version, resin abrasive cutting
wheels are suitable only for dry cutting or only for
wet cutting.
5.3.1 Composite resin abrasive cutting
wheels suitable only for dry cutting
During dry cutting, wear a suitable dust mask.
If fumes or smoke are anticipated (e.g., when
cutting composite materials), wear respiratory
protection.
5.3.2 Composite resin abrasive cutting
wheels suitable only for wet cutting
Use abrasive cutting wheel only with
water.
To bind dust, the abrasive cutting wheel must be
supplied with at least 1 liter of water per minute.
To avoid a reduction in cutting performance, the
abrasive cutting wheel must be supplied with not
more than 4 liters of water per minute.
After using the abrasive cutting wheel, the wheel
should be allowed to continue spinning at operat‐
ing speed for approx. 3 to 6 seconds without
