3.4 Temperature-dependent motor protection
The temperature-dependent motor protection system monitors current input and motor temperature and
thus prevents the power tool overheating.
If the motor is overloaded through application of excessive working pressure, the power tool's performance
drops noticeably or it may stall completely.
If the power tool stalls or slows significantly due to overloading, release the pressure applied to the tool and
then allow it to run under no load for approx. 30 seconds.

When grinding with straight grinding discs and cutting with cutting discs in metalworking applications,
use the standard guard with front cover.
