Mounting the Protective Devices
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing 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 service agent for
maintenance.
Protection Guard for Cutting
For cutting with bonded abrasives, always use
the protection guard for cutting 10.
Provide for sufficient dust extraction when
cutting stone.
Mounting the blade guard (see figure B)
The protection guard for cutting 10 is mounted on-
to the protection guard for grinding 7 until it engag-
es.
Adjusting the Protection Guard
Turn the protection guard to the desired position
until it engages. No tool is required for this.
Mounting the Grinding Tools
(see figure B)
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as dur-
ing 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 8 and all parts to be
mounted.
For tightening or loosening the grinding tools, push
the spindle lock button 2 forwards and simultane-

ously turn the grinding tool to fix the grinder spin-
dle.
Actuate the spindle lock button only when the
grinder spindle is at a standstill. Otherwise, the
machine may become damaged.
Grinding/Cutting Disc
Capacity
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.
When using diamond cutting discs, pay attention
Reserve
that the direction-of-rotation arrow on the diamond
cutting disc and the direction of rotation of the ma-
chine (see direction-of-rotation arrow on the hous-
ing) agree.
See graphics page for the mounting sequence.
Attach the grinding tool using the bolt 11. Tighten
the bolt using the hex key 13 until the washer of the
bolt is flush with the grinding tool.
After mounting the grinding tool and before
switching on, check that the grinding tool is
correctly mounted and that it can turn freely.
Make sure that the grinding tool does not
graze against the protection guard or other
parts.
Approved Grinding Tools
The permissible speed [min
tial speed [m/s] of the grinding tools used must at
least match the values given in the table.
Therefore, observe the permissible rotational/cir-
cumferential speed on the label of the grinding
tool.
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 reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dust, such as oak or beech dust, is con-
sidered carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
