Protective guard for grinding
Always use the protective guard for grinding
r
(7) when grinding.
Protective guard for cutting
Always use the protective guard for cutting (10)
r
when cutting with bonded abrasives.
Provide sufficient dust extraction when cutting
r
stone.
Fitting the Protective Guard (see figure B)
Insert the protective guard for cutting (10) onto the protective
guard for grinding (7) until this engages firmly.
Adjusting the Protective Guard (see figure B)
Turn the protective guard to the required position and ensure
the protective guard is engaged. No tool is required for this.
Fitting the abrasive tools
Remove the battery from the power tool before
r
carrying out work on the power tool (e.g. main-
tenance, changing tool, etc.). The battery should
also be removed for transport and storage.
There is risk of injury from unintentionally pressing the on/
off switch.
Do not touch grinding and cutting discs until
r
they have cooled down. The discs can become very
hot while working.
Clean the grinding spindle (8) and all parts to be mounted.
To tighten or loosen the abrasive tools, push the spindle lock
button (2) forwards and simultaneously turn the grinding tool
to fix the grinding spindle in place.
Do not press the spindle lock button while the
r
grinding spindle is moving. The power tool may be-
come damaged if you do this.
Grinding/cutting disc
Pay attention to the dimensions of the abrasive tools. The dia-
meter of the hole must match that of the mounting flange. Do
not use an adapter or reducer.
When using diamond cutting discs, make sure that the direc-
tion of rotation arrow on the diamond cutting disc corresponds
to the direction of rotation of the machine (see direction of ro-
tation arrow on the housing).
See the graphics page for fitting instructions.
To remove the grinding/cutting disc, push the spindle
lock button (2) forwards while simultaneously turning on the
grinding/cutting disc (12) in order to fix the grinding
spindle (8) in place (see figure C1).
Use a hex key (13) to remove the clamping bolt with
washer (11) and take off the grinding/cutting disc (12)
(see figure C2).
22
To attach the grinding/cutting disc, screw in the clamp-
ing bolt with washer (11). Tighten the bolt using the hex
key (13) until the washer of the bolt is flush with the grinding/
cutting disc (12) (see figure C3).
Then push the spindle lock button (2) back again
(see figure C4).
After fitting the abrasive tool, check that the ab-
r
rasive tool is fitted correctly and can turn freely
before switching on the power tool. Make sure
that the abrasive tool does not brush against
the protective guard or other parts.
Approved Grinding Tools
You can use all the abrasive tools mentioned in these operat-
ing instructions.
-1
The permissible speed [min ] or the circumferential speed [m/
s] of the abrasive tools used must at least match the values
given in the table.
It is therefore important to observe the permissible rota-
tional/circumferential speed on the label of the abras-
ive 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 re-
actions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carcino-
genic, especially in connection with wood-treatment additives
(chromate, wood preservative). Materials containing asbestos
may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
