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 assembling instructions.
To fasten the grinding/cutting disc, screw on the clamping
nut (10) and tighten with the combination wrench (4).
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.
Flap disc
Always fit the hand guard (14) when working with the
u
flap disc.
Rubber sanding pad
Always fit the hand guard (14) when working with the

Always fit the hand guard (14) 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

Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
