▪ Always check the position of ON/OFF switch.
The power tool must be connected to the
power supply socket only when this switch is
in OFF position. If the plug is connected to
a receptacle while the power switch is in the
ON position, the power tool will start operat-
ing immediately, which could cause a serious
accident.
▪ Make sure that the cord and the plug are in
order. If the replacement of the supply cord is
necessary, this has to be done by the manu-
facturer or his agent in order to avoid a safety
hazard.
WARNING: Always switch off and un-
plug the power tool prior to any adjustment,
servicing or maintenance.
▪ Make sure the grinding wheel diameter and
thickness do not exceed the values specified
on the name plate. The peripheral speed in-
dicated on the wheel must not be less than
80 m/s. The wheels must be stored according
the recommendations of the manufacturer.
▪ In case the work area is remote from the pow-
er source, use as short as practicable exten-
sion cord with proper cross-section.
▪ Check that the auxiliary handle is properly
mounted and reliably tightened.
