Rough-grinding
t^okfkd>
Never use cutting-off wheels for rough-
grinding.
– Angle of wheel 20–40° for best cutting
performance.
– Applying moderate pressure, move
the angle grinder backwards and forwards.
As a result, the workpiece will not become
too hot and there will be no discoloration;
nor will there be any grooves.
Cut-off grinding
– A special cutting guard must be used
for cut-off grinding.
– Do not press, tilt or oscillate the power tool.
– Angle grinder must always operate in the
counter direction. Otherwise, there is a risk
of the angle grinder jumping uncontrollably
out of the groove.
– Adjust the feed to the material which is to
be work: the harder the material, the slower
the feed.

Maintenance and care
t^okfkd>
Before carrying out any work on the angle
grinder, always pull out the mains plug.
Cleaning
t^okfkd>
If metals are ground or cut over a prolonged
period, conductive dust may become
deposited inside the housing. Impairment of
the protective insulation! Operate the power
tool via a residual-current-operated circuit-
breaker (tripping current 30 mA).
Regularly clean the power tool and ventilation
slots. Frequency of cleaning is dependent
on the material and duration of use.
Regularly blow out the housing interior and
motor with dry compressed air.
Carbon brushes
The angle grinder features cut-off carbon
brushes.
When the wear limit of the cut-off carbon
brushes is reached, the angle grinder switches
off automatically.

When the power tool is being used, the carbon
brushes can be seen sparking through the rear
air inlet apertures.
If the carbon brushes spark excessively, switch
