2.11 Using a generator or transformer
This power tool may be powered by a generator or transformer when the following conditions are fulfilled: The unit
must provide a power output in watts of at least twice the value printed on the type identification plate on the power
tool. The operating voltage must remain within +5% and -15% of the rated voltage at all times, frequency must be in
the 50 – 60 Hz range and never above 65 Hz, and the unit must be equipped with automatic voltage regulation and
starting boost.
Never operate other power tools or appliances from the generator or transformer at the same time. Switching other
power tools or appliances on and off may cause undervoltage and / or overvoltage peaks, resulting in damage to the
power tool.
