Quick-clamping Nut
For convenient changing of grinding tools with-
out the use of additional tools, you can use the
quick-clamping nut 12 instead of the clamping
nut 11.
f The quick-clamping nut 12 may be used only
for grinding or cutting discs.
Use only a flawless, undamaged quick-clamping
nut 12.
When screwing on, pay attention that the side
of the quick-clamping nut 12 with printing does
not face the grinding disc; the arrow must point
to the index mark 22.
Lock the grinder spin-
dle with the spindle
lock button 1. To tight-
en the quick-clamping
nut, firmly turn the
grinding disc in clock-
wise direction.
A properly attached, un-
damaged quick-clamp-
ing nut can be loosened
by hand when turning
the knurled ring in anti-
clockwise direction.
Never loosen a tight
quick-clamping nut
with pliers. Always use
the two-pin spanner.
Insert the two-pin span-
ner as shown in the illustration.
Approved Grinding Tools
All grinding tools mentioned in these operating
instructions can be used.
The permissible speed [min
-1
] or the circumfer-
ential speed [m/s] of the grinding tools used
must at least match the values given in the table.
Therefore, observe the permissible rotation-
al/circumferential speed on the label of the
grinding tool.
Rotating the Machine Head
f Before any work on the machine itself, pull
the mains plug.
The machine head
can be rotated with
respect to the ma-
chine housing in 90°
steps. In this man-
ner, the On/Off
switch can be
brought into a more
convenient position
for special working
situations, e.g. for
left-handed per-
sons.
Completely unscrew the four screws. Rotate the
machine head carefully, without removing it
from the housing, to the new position. Screw in
and tighten the four screws again.
Dust/Chip Extraction
f Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
