Do not touch grinding and cutting discs until they have
u
cooled down. The discs can become very hot while work-
ing.
Clean the grinding spindle (7) and all the parts to be fitted.
Lock the grinding spindle with the spindle lock button (1)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grind-
u
ing spindle is moving. The power tool may become dam-
aged if you do this.
Grinding/cutting disc
Pay attention to the dimensions of the abrasive tools. The
diameter of the hole must match that of the mounting flange.
Do not use an adapter or reducer.
When using diamond cutting discs, ensure that the arrow in-
dicating the direction of rotation on the diamond cutting disc
matches the direction of rotation of the power tool (see the
direction of rotation arrow on the machine head).
See the graphics page for fitting instructions.
To fasten the grinding/cutting disc, screw on the clamping
nut (12) and tighten it with the combination wrench(5)/(6);
see the "Quick-clamping nut" section.
After fitting the abrasive tool, check that the abrasive
u
tool is fitted correctly and can turn freely before
switching on the power tool. Make sure that the abras-
ive tool does not brush against the protective guard or
other parts.
Mounting flange for grinding spindle M 14:
A plastic part (O-ring) is fitted around the cent-
ring collar in the mounting flange (10). If the
O-ring is missing or damaged, the mounting
flange (10) must be replaced before operation
can resume.
Mounting flange for grinding spindle M 10: The mounting
flange can be used on either side.
Flap disc
Always fit the hand guard (17) when working with the
u
flap disc.
Rubber sanding pad
Always fit the hand guard (17) when working with the
u

Screw on the round nut (20) and tighten it with the combina-
tion wrench (5)/(6).

Always fit the hand guard (17) when working with the
u
cup brush or disc brush.
See the graphics page for fitting instructions.
The cup brush/disc brush must be screwed onto the grinding
spindle until it rests firmly against the grinding spindle flange
at the end of the grinding spindle thread. Tighten the cup
brush/disc brush with an open-ended spanner.

u
grinding or cutting discs.
Only use quick-clamping nuts (13) that are in good work-
ing order and not damaged.
When screwing on, make sure that the printed side of the
quick-clamping nut (13) is not facing the grinding disc;
the arrow must be pointing towards the index mark (23).

plications, e.g. for left-
handed tool users.
Completely unscrew the
four screws. Rotate the ma-
chine head carefully,
