Press the protection guard 7 onto the spindle
collar until the shoulder of the protection guard
is seated against the flange of the machine, and

ner that sparking is prevented in the direc-
tion of the operator.

erwise the power tool may not continue to
be used under any circumstances and must
be taken to an after-sales service agent.
Note: The encoding keys on the protection
guard 7 ensure that only a protection guard that
fits the machine type can be mounted.
Protection Guard for Cutting
For cutting metal, always work with the pro-
tection guard for cutting 8.
For cutting stone, always work with the cut-
ting guide with dust extraction protection
guard 18.
The protection guard for cutting 8 is mounted in
the same manner as the protection guard for
grinding 7.
Auxiliary Handle
Operate your machine only with the auxilia-
ry handle 5.
Screw the auxiliary handle 5 on the right or left
of the machine head depending on the working
method.
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 14 or with the cup brush/wheel
brush/flap disc, always mount the hand
guard 13.
The hand guard 13 is fastened with the auxiliary
handle 5.
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.
Clean the grinder spindle 6 and all parts to be
mounted.
For clamping and loosening the grinding tools,
lock the grinder spindle with the spindle lock
button 2.
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 11 and tighten with the two-
pin spanner; see Section "Quick-clamping Nut ".
