sponds to the value indicated on the name
plate with technical data of the tool.
▪ Always check the position of ON/OFF switch.
The power tool must be connected and dis-
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 operating 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.

ADjUSTING THE ROTATION SPEED
(M 750E HD, M 850E HD, M 1050E HD,
M 1200E PLUS HD, M 1200CES HD,
M 1400CES HD, M 1400CES PlUS HD)
Continuous operation at low rpm is not recom-
mended for the following machines: М 750Е HD,
M 850E HD, М 1050Е HD.
The rotation speed can be varied smoothly by
turning electronic regulator 8, placed on the
rear of the grinder. In the table below the rec-
ommended regulator positions for the different
areas of applications are specified:

Models M 850E HD, M 1050E HD, M 1200E HD
are equipped with full-wave electronics for
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and control.
Model M 1200E plus HD is equipped with full-
wave electronics for:
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and control.
- Brief overload protection (upon jamming
the wheel). To resume operation release the
ON/OFF switch and then press it again;

again.
Models M 1200CES HD and M 1400CES HD
feature full-wave tachoconstant electronics for:
- Soft start and restriction of the starting cur-
rent;
