If a safety guard is supplied with the hand tool, it is
imperative that the safety guard be used.

elect speed
Select a speed from the table and set this for the grinding
tool at the setting wheel.
Level 1: 11000min-1
Level 2: 13000min-1
Level 3: 16000min-1
During operation never exceed the speed which
has been matched to the grinding tool specifica-
tions!

The switch must be at the OFF position, i.e. the «0» is
visible. To switch ON the tool, press the switch. The «1»
becomes visible.
Before turning on the machine, make sure to re-
move wrenches and adjusting tools. Before start-
ing the machine, hold the hand tool against turn-
ing!

Temperature range during operation: 0 to +50°C
Relative air humidity: 90% at +30°C, 65% at +50°C
To avoid strong looping movements and beaming
of the flexible shafts, the working pressure must
be reduced.

emperAture
dependent oVerloAd protection
For protection against overheating, when a critical tem-
perature is reached the electronic safety feature switches
into the cool-down mode. The machine then continues to
run at a speed of approx: 11000min
constant speed control is deactivated. After a cool-down
time of approx. 10 - 20 s the machine is again ready for
operation. Turn the machine off and back on again to acti-
vate the electronic constant speed control. With the tool at
operating temperature the temperature-dependent over-
load protection reacts correspondingly earlier.
