Compare the mains voltage and frequency with the details on the
model plate.
Connect the device only to a safe power supply via FI-circuit
breaker (IA = 30 mA).
The device may only be connected to power outlets with a ground
contact (PE – protective earth).
The mains plug serves as a safe disconnecting device from the
power supply network and must be freely accessible at all times.
Do not start the device if it has a damaged mains cable.
Check the mains cable regularly for signs of damage.
We disclaim all liability for damage caused by incorrect line
voltages!
Unit parts may develop high surface temperatures. A hot surface
means it has a temperature of 60 °C / 140 °F or more.
Let the device cool down to an uncritical safe temperature.
Use safety gloves.
