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.

-CAUTION-
■ The guard is used in a partly
open position for working close
to edges.
■ The rotating cup wheel presents
a risk of serious injury.
■ Work carefully when the guard
is open and close it again when
you have finished working at
the edge.
-NOTE- More dust may escape from the guard when
working at edges.
Adjusting the guard
1. Switch the tool off.
2. Disconnect the supply cord plug from the socket.
3. Open the clamping lever.
4. Rotate the upper and lower sections of the guard in
opposing directions until they are in a suitable position.
5. Close the clamping lever
-NOTE- The guard engages perceptibly in the closed,
normal position.
-NOTE- If the guard is not held securely when the lever
is closed, tighten the clamping band by turning the adjust-
ing screw in a clockwise direction.
If the guard cannot be moved when the lever is open,
release the clamping band by turning the adjusting screw
in a counter-clockwise direction.
6.2 Side handle
6.2.1 Using and adjusting the side handle
For safety reasons, the side handle must always be used.
It can be adjusted in two axes until in the most favourable
working position:
– Two angled positions for right or left-handed use
– Pivoted forwards / back in increments
1. Switch the tool off.
2. Disconnect the supply cord plug from the socket.
3. Release the side handle by turning the clamping screw
in a counter-clockwise direction.
4. Bring the side handle into the desired position.
5. Tighten the clamping screw by turning it in a clock-
wise direction.
6.3 Diamond cup wheel
● The tool must always be switched off and the supply
cord plug disconnected before manipulating the cup
wheel in any way.
● Press in the spindle lockbutton (only when rotation
has stopped).
● When changing the cup wheel, clean all cup wheel
mounting parts.
● Use only original Hilti diamond cup wheels, clamping
flanges and clamping nuts.
