6. Before use

It is essential that the safety precautions printed in these
operating instructions are read and observed.
■The cup wheel or parts of the
guard may become hot during
use.
■These parts may burn your hands.
■ Wear safety gloves when chang-
ing the cup wheel or adjusting
the guard.
6.1 Guard
-WARNING- The tool may be used only with the guard
fitted.
A damaged or incomplete guard must be replaced imme-
diately.
6.1.1 Adjusting the guard
The extraction hose connector can be brought into the
most favourable position for working by rotating the entire
guard.
Rotating the guard
1. Switch the tool off.
2. Disconnect the supply cord plug from the socket.
3. Open the clamping lever.
4. Rotate the guard.
-NOTE- When the extraction hose connector comes
into contact with the opened lever, the guard can be
rotated further by moving it downwards.
5. Close the clamping lever.
6.1.2 Adjusting the guard to the work surface
1. Switch the tool off.
2. Disconnect the supply cord plug from the socket.
3. Lay the tool down on the cup wheel.
4. Open the clamping lever.
5. Rotate the guard and adjust it to the optimum height.
-NOTE- For optimum dust extraction while grinding,
the lamellar seal should be almost in contact with the
work surface (gap 0 ... 1 mm).
6. Close the clamping lever.
6.1.3 Adjusting the guard for working close to edges
The opening in the lower section of the guard can be
rotated until part of the cup wheel is exposed. This is of
advantage, for example, when grinding close to a wall.
