English
In the event of changes in cutting
behavior (e. g., increased vibration,
reduced cutting performance), stop work
and eliminate the causes of the
changes.
Reactive forces
The most frequently occurring reactive
forces are kickback and pull-in.
Dangers of kickback
Kickback can result in fatal injuries.
Kickback occurs when the cut-off
machine is suddenly thrown up and back
in an uncontrolled arc towards the
operator.
Kickback occurs if, for example, the
abrasive wheel
gets jammed – primarily in its upper
–
quarter, or
is abruptly braked through friction
–
contact with a solid object
Reducing the risk of kickback
Work cautiously and methodically
–
Hold the cut-off machine firmly with
–
both hands and maintain a secure
grip

Do not use the upper quarter of the
–
abrasive wheel for cutting. Use
extreme caution when entering the
abrasive wheel in a cut, do not twist
or push into the cut
Avoid wedge effect, the severed
–
part must not brake the abrasive
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 wheel.
The object to be cut must be
–
secured and supported so that the
kerf remains open during and after
cutting
Objects to be cut must therefore be
–
fully supported 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
Depending on the version, resin
–
abrasive wheels are only suitable
for dry cutting or only for wet cutting.
Always use wet cutting with
composite resin abrasive wheels
that are suitable only for wet cutting
Pulling away
The cut-off machine pulls forwards,
away from the user, when the abrasive
wheel touches the object to be cut from
above.
