Mounting the Protective Devices
 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.
Note: After breakage of the grinding disc during operation or
damage to the holding fixtures on the protection guard/power
tool, the machine must promptly be sent to an after-sales ser-
vice agent for maintenance. For addresses, see section "Af-
ter-sales Service and Application Service".
Protection Guard for Grinding
Place the protection guard 12 on
the power tool's holding fixture
until the protection guard's cod-
ing lugs line up with the holding
fixture. When doing so, press and
hold the unlocking lever 1.
Press the protection guard 12 on-
to the spindle collar until the
shoulder of the protection guard
is seated against the flange of the
machine, and turn the protection
guard until it can clearly be heard
to engage.
Adjust the position of the protec-
tion guard 12 to the requirements of the work process. For
this, press the release lever 1 upward and turn the protection
guard 12 to the required position.
 Always adjust the protection guard 12 in such a manner
that all 3 red cams of release lever 1 engage into the
corresponding notches of the protection guard 12.
 Adjust the protection guard 12 in such a manner that
sparking is prevented in the direction of the operator.
 The protection guard 12 may be turned only upon actu-
ation of the release lever 1! Otherwise the power tool
may not continue to be used under any circumstances
and must be taken to an after-sales service agent.

Capacity
tection guard for cutting 17.
> 80 – 100 %
 Provide for sufficient dust extraction when cutting
> 60 – ≤ 80 %
stone.
> 40 – ≤ 60 %
The protection guard for cutting 17 is mounted in the same
> 20 – ≤ 40 %
manner as the protection guard for grinding 12.
> 0 – ≤ 20 %
Cutting Guide with Dust Extraction Protection Guard

grinding 12.
Auxiliary Handle
 Operate your machine only with the auxiliary handle
10.
Screw the auxiliary handle 10 on the right or left of the ma-
chine head depending on the working method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle reduces the vibra-
tions, making operation more comfortable 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 20 or with
the cup brush/wheel brush/flap disc, always mount the
hand guard 19.
The hand guard 19 is fastened with the auxiliary handle 10.
Mounting the Grinding Tools
 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.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Clean the grinder spindle 11 and all parts to be mounted.
For clamping and loosening the grinding tools, lock the grind-
er spindle with the spindle lock button 3.
 Actuate the spindle lock button only when the grinder
spindle is at a standstill. Otherwise, the machine may be-
come 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 reducers or adapters.
