CAUTION
● Use Commercial power supply to operate the wrench.
● Follow the instructions below when using generator.
■ Use 50-60Hz (AC) sinusoidal power supply without high harmonic wave.
Power supply including high harmonic wave may cause malfunction or

Power requires almost 2kW (2kVA) per one month.
■ The operating voltage must remain /-10% of the rated voltage at
all times.
■ Do not use an inverter generator.
(Inverter generator: The engine rpm will speed up and slow down automatically due to
the wattage being pulled from the generator.)

■ Welder generators may cause malfunction or breakage of the control base
installed in the wrench.
■ Some welder generators may produce electrical noise that may cause the
