Cup Brush/Disc Brush
For operations with the cup brush/wheel brush, always
mount the hand guard 18.
See graphics page for the mounting sequence.
The cup brush/disc brush must be able to be screwed onto
the grinder spindle until it rests firmly against the grinder
spindle flange at the end of the grinder spindle threads. Tight-
en the cup brush/disc brush with an open-end spanner.
Quick-clamping Nut
For convenient changing of grinding tools without the use of
additional tools, you can use the quick-clamping nut
14
in-
stead of the clamping nut
13
.
The quick-clamping nut 14 may be used only for grind-
ing or cutting discs.
Use only a flawless, undamaged quick-clamping nut 14.
When screwing on, pay attention that the side of the
quick-clamping nut 14 with printing does not face the
grinding disc; the arrow must point to the index mark
28.
Lock the grinder spindle with
the spindle lock button
2
. To
tighten the quick-clamping
nut, firmly turn the grinding
disc in clockwise direction.
A properly attached, undam-
aged quick-clamping nut can
be loosened by hand when
turning the knurled ring in an-
ticlockwise direction.
Never loosen a tight quick-
clamping nut with pliers.
Always use the two-pin
spanner.
Insert the two-pin
spanner as shown in the illus-
tration.
Approved Grinding Tools
All grinding tools mentioned in these operating instructions
can be used.
The permissible speed [min
-1
] or the circumferential speed
[m/s] of the grinding tools used must at least match the values
given in the table.
Therefore, observe the permissible
rotational/circumferen-
tial speed
on the label of the grinding tool.
Rotating the Machine Head
Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
The machine head can be
rotated with respect to
the machine housing in
90° steps. In this man-
ner, the On/Off switch
can be brought into a
more convenient position
for special working situa-
tions, e.g. for left-handed
persons.
Completely unscrew the
four screws. Rotate the
machine head carefully,
without removing it from the hous-
ing,
to the new position. Screw in and tighten the four screws
again.
Dust/Chip Extraction
Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace.
Dust can
easily ignite.
