English
Kickback occurs if, for example, the abrasive cut‐
ting wheel
– gets jammed – primarily in its upper quarter, or
– is abruptly braked through friction contact with
a solid object
QuickStop abrasive cutting wheel brake
When the abrasive cutting wheel brake is
engaged, the abrasive cutting wheel will come to
a standstill in a split second –
see chapter "abrasive cutting wheel Brake" in
this User Manual.
To reduce the risk of kickback
– Work cautiously and avoid situations which
could cause kickback.
– Hold the cut-off machine firmly with both
hands and maintain a secure grip
– If possible, avoid using the upper quarter of
the abrasive cutting wheel for cutting. Use
extreme caution when guiding the abrasive
cutting wheel into a cut, do not twist or push
into the cut
– Avoid any wedge effect - the severed part
must not brake the abrasive cutting wheel
– Always be aware that the object to be cut may
move and other factors may cause the cut to
close and jam the abrasive cutting wheel.
– The object to be cut must be secured and sup‐
ported so that the kerf remains open during
and after cutting

2 Safety Precautions and Working Techniques
– Objects to be cut must therefore be fully sup‐
ported and must be secured against rolling
away, slipping off or vibrations
– Support an uncovered pipe stable and solid, if
necessary, use wedges – always bear in mind
a proper support and ground – material may
crumble away,
– Always work with water and wet cutting when
using diamond abrasive wheels
2.11.1 Pull away from
The cut-off machine pulls forward, away from the
user, when the abrasive wheel touches the
object to be cut from above.
2.12 Working – cutting off
The abrasive cutting wheel must be
guided straight in the cut, without tilt‐
ing. Never exert lateral pressure on
the abrasive cutting wheel.
Do not use for lateral grinding or
scrubbing.
