power on the machine again.
Operating near the overload (with the red lamp flashing) is allowed; however,
never allow the motor temperature to exceed 85°C (185°F) because this can lead to
damage of the motor windings. After every hour of operating under full load, stop the
motor for 10
–15 minutes. Never cool the motor by running without load because it will
become heated even faster than when working with load.
After the work is finished, stop the motor using the STOP button and set the
power switch to the position ‘O’. Use petroleum ether to clean oil from the workpiece.
