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
the wheel). To resume operation release the
ON/OFF switch and then press it again;
- Continuous overload protection (the ther-
mal protection switches the machine off to pro-
tect the motor from inadmissible overheating).
Upon actuating the thermal protection the ma-
chine becomes disabled. Тo 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.

WHEEL GUARD
WARNING: The wheel guard 2.1 for
grinding wheel or the wheel guard 2.2 for
cutting wheel (for grinding wheel 4.1 or cut-
ting wheel 4.2 accordingly) must always be
mounted on the machine!
Its position can be different and depends on
which side the auxiliary handle is placed, as well
as when the machine is mounted on a stand.
GRINDING WHEEL REPLACEMENT
Secure spindle 1 by depressing the spindle lock
button 9 provided on the gear case.
WARNING: Never press button 9
while the spindle is still rotating!
(With this button depressed turn the spindle till
its pronounced going deeper). ). Unscrew the
xing ange 5 by a lock nut wrench. Place the
new wheel on thesupport ange 3 with the in-
scriptions facing up, and screw down ange 5
facing its at side towards the wheel, using the
lock nut wrench. Use blotters if the wheel has
been delivered with them. After replacing the
wheel operate the machine with the new wheel
in no load mode for one minute. Vibrating or
otherwise improperly rotating wheels must be
replaced immediately and discarded.
Cup brushes 10 are screwed directly on spindle
1 by means of an open-end spanner. (Check if
the brush thread length is sufcient to accept the
spindle thread.)
Grinding and polishing with abrasive sanding
disks is accomplished by means of plastic rub-
ber backing disk (pad) 11, under which sanding
disks and polishing jackets 12 are mounted.
Place plastic backing pad 11 on the support
ange 3 and secure it with lock nut 13, delivered
with the tool. In case the exible backing pad
is equipped with a ange, the pad is screwed
directly onto the spindle by a wrench without
using the xing ange 5. The pad with ange
may be a resin lled sponge, foam polyurethane
sponge with plastic insert for the nut with hook-
and-loop fastening to the sandpaper or the bon-
net. After replacing the pad perform a trial run
for one minute at no load. Vibrating or otherwise
improperly rotating pads must be replaced im-
mediately.
MOUNTING THE WHEEL GUARD
Before performing the following operations,
switch the machine off and withdraw the plug
from the socket.
Mounting the wheel guard (fig. 1)
- Rotate the black plastic ring (Fig. 2a), so
that the crevice S of the ring coincides with the
groove for the tooth of the xing lever L.
- Place the wheel guard in non-operating
position (Fig.2a) so that the four teeth coin-
cide with the four grooves in the bearing seat
(Fig.2b).
- Press the fastening lever L (g.3) to re-
lease it.
