You can work near the overload (when the red lamp flashes), but do not let the
motor temperature increase more than 85°C (185°F). This can lead to damage of the
motor windings. After each hour of work under full load, stop the motor for 10
–
15 minutes. Do not try to decrease the motor temperature by working without load.
The motor will then get hotter than when working with load.
After the work is finished, press the STOP button to stop the motor. Then, set the
power switch to ‘O’. Use petroleum ether to clean oil from the workpiece.
Clean the machine with a cotton cloth and no chemical agents.
