Operation

Starting operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V, and
power tools marked with 127 V can also be
operated with 115 V.
Hold power tool by insulated gripping sur-
faces 16 and auxiliary handle 4 only. The
accessory may contact hidden wiring or its
own cord. Accessory contacting a "live" wire
may make exposed metal parts of the power
tool "live" and shock the operator.
When operating the machine with power from
mobile generators that do not have sufficient
reserve capacity or are not equipped with suit-
able voltage control with starting current ampli-
fication, loss of performance or untypical
behavior can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.
