▪ The machine may be delivered with the wheel
mounted at the factory. Ensure that the wheel
is mounted properly and fixed reliably prior to
the initial and any following operation.
▪ Make sure the power supply voltage corre
-
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 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.
SWITCHING ON - SWITCHING Off
Switching on: Push the back end of the ON/OFF
switch 7 down and then forward in the direction
of the arrow until its front end will sag, thus fix
-
ing itself.
Switching off: press the back, lifted end of switch
7 and release it to return in its initial position.
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:
Area of application
Regulator position
1. Plastics grinding with plastic disk
A - C
and abrasive cloth (paper)
2. Wood grinding and removing
B - D
lacquer and dye coatings
3. Metal grinding with plastic disk and
C - f
abrasive cloth (paper)
4. Dust removing with cup brush
D - f
5. Rough cleaning, metal or stone cutting

6. Polishing with plastic disk and
A - B
polishing jacket
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;
- Non-self starting safety (NVR) after re-
storing the mains supply. To resume operation
release the ON/OFF switch and then press it
again.
Models M 1200CES HD and M 1400CES HD
feature full-wave tachoconstant electronics for:
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and control and main-
taining constant rpm upon overloading;
- Brief overload protection (upon jamming
the wheel). To resume operation release the
ON/OFF switch and then press it again;
- Overload protection (adaptable current
protection). To protect the machine motor from
inadmissible overheating the power is reduced
without functionality being lost;
- Non-self starting safety (NVR) after re-
storing the mains supply. To resume operation
release the ON/OFF switch and then press it
again.
Model M 1400CES HD plus features full-wave
tachoconstant electronics for:
- Soft start and restriction of the starting cur-
rent;
- Speed pre-selection and control and main-
taining constant rpm upon overloading;
- Brief overload protection (upon jamming
