Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduc-
es the vibrations, making operation more com-
fortable and secure.
Do not make any alterations to the auxiliary
handle.
Do not continue to use an auxiliary handle if it
is damaged.
Hand Guard
For operations with the rubber sanding
plate 18 or with the cup brush/wheel brush/
flap disc, always mount the hand guard 17.
The hand guard 17 is fastened with the auxiliary
handle 6.
Mounting the Grinding Tools
Before any work on the machine itself (e. g.
maintenance, 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.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Clean the grinder spindle 7 and all parts to be
mounted.
For clamping and loosening the grinding tools,
lock the grinder spindle with the spindle lock
button 1.
Actuate the spindle lock button only when
the grinder spindle is at a standstill. Other-
wise, the machine may become damaged.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding
tools. The mounting hole diameter must fit the
mounting flange without play. Do not use reduc-
ers or adapters.

When using diamond cutting discs, pay atten-
tion that the direction-of-rotation arrow on the
diamond cutting disc and the direction of rota-
tion of the machine (see direction-of-rotation ar-
row on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc, screw on
the clamping nut 12 and tighten with the two-
pin spanner; see Section "Quick-clamping Nut ".
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn free-
ly. Make sure that the grinding tool does
not graze against the protection guard or
other parts.
An O-ring (plastic part) is in-
serted in the mounting flange
10 around the centring collar. If
the O-ring is missing or is dam-
aged, it must in all cases be re-
placed (article number
1 600 210 039) before the
mounting flange 10 is mounted.
Flap Disc
For operations with the flap disc, always
mount the hand guard 17.
Rubber Sanding Plate
For operations with the rubber sanding
plate 18, always mount the hand guard 17.
See graphics page for the mounting sequence.
Screw on the round nut 20 and tighten with the
two-pin spanner.
Cup Brush/Disc Brush
For operations with the cup brush/wheel
brush, always mount the hand guard 17.
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. Tighten the
cup brush/disc brush with an open-end span-
ner.
