Practical advice
Rough grinding
u Always use the protective guard for grinding (7) when
cutting work with bonded cutting discs, there is an in-
creased risk of being exposed to sparks, particles and
disc fragments if the disc breaks.
When carrying out abrasive cutting, use a moderate feed
that is suited to the material being machined. Do not exert
pressure on the cutting disc and do not tilt or swing the
power tool.
Do not attempt to reduce the speed of a cutting disc coming
to a stop by applying pressure from the side.

cutting (8) or the protective guard for grinding (7)
with a fitted cover for cutting (11) can impact the
workpiece and lead to a loss of control.
The best rough grinding results are achieved with a set angle
of 30° to 40°. Move the power tool back and forth with mod-
erate pressure. This will ensure that the workpiece does not
become too hot or discolour and that grooves are not
formed.

ures than conventional grinding discs.
