Auxiliary Handle
For all work with the machine, the auxiliary
handle must be mounted.
Screw the auxiliary handle 4 into the head of the
machine according to the working method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle re-
duces the vibrations, making operation more
comfortable and secure.
Do not make any alterations to the aux-
iliary handle.
Do not continue to use an auxiliary handle if it is
damaged.
Hand Guard
For work with the rubber sanding plate 19 or with
the cup brush 22/disc brush/flap disc, the hand
guard 18 (accessory) is to be mounted.
The hand guard 18 is fastened with the auxiliary
handle 4.
Mounting the Grinding Tools
Before any work on the machine itself, pull the
mains plug.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
It is recommended to use the quick-clamping
nut 11. When using the clamping nut 16 in-
creased effort to loosen the clamping nut must be
taken into account.
Clean the grinder spindle and all parts to be
mounted. For clamping and loosening the grind-
ing tools, lock the grinder spindle 6 with the spin-
dle lock button 2.
Actuate the spindle lock button 2 only when
the grinder spindle is at a standstill!
Quick Clamping Nut
When using the quick-clamping nut 11, grinding
tools can be mounted without additional tools.
Use only a flawless, undamaged quick-clamp-
ing nut 11.

Grinding/Cutting Disc
Pay attention to the dimensions of the grind-
ing disc. The mounting hole diameter must fit
the mounting flange 5 without play. Do not
use reducers or adapters.
When using a diamond cutting disc, take care
that the direction-of-rotation arrow on the dia-
mond cutting disc and the direction of rotation of
the machine (direction-of-rotation arrow on the
machine head) agree.
For mounting, see the illustration page.
Position the grinding/cutting disc onto the mount-
ing flange 5. Ensure that the grinding tool is
seated centred and without play on the mounting
flange.
Screw on the quick-clamping nut 11 and tighten
the grinding disc.
After mounting the grinding tool and be-
fore switching on, check that the grind-
ing tool is correctly mounted and that it
can turn freely.

Lock the grinder
spindle with the spin-
dle lock button 2.
Tighten the quick-
clamping nut by
firmly turning the
grinding disc in clock-
wise direction.
A properly attached,
undamaged quick-
clamping 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 spanner as
shown in the illustra-
tion.
