Attention!
Polishing against the direction of rotation of the po-
lishing wheels can damage the polishing wheels and
thus cause injuries.
Replacing the grinding disc / polishing wheel
(Fig. 5+6)
m WARNING!
- The grinding disc (12) or polishing wheel (2) used
must never be larger than the prescribed diam-
eter.
- Change the grinding disc (12) or polishing wheel
(2) if the outer diameter is less than 50 mm.
• Using a Phillips screwdriver, rotate out the fixing
screw (39) of the side protective covers (40). Remove
the protective covers (40) on both sides (Fig. 6).
• If you wish to change the polishing wheel (2), remove
the locking pin (38a) of the flexible shaft attachment
(38). Then pull the flexible shaft attachment (38) off
the shaft (34).
• Unscrew the union nut (37) from the shaft (34) us-
ing a 17 mm spanner. Hold the grinding disc (12) or
polishing wheel (2) with one hand to build up coun-
ter-pressure.
• Remove the tension washer (36) and grinding (12) or
polishing wheel (2).
• Place the new grinding disc (12) or polishing wheel
(2) on the shaft (34).
• Push the tension washer (36) back onto the shaft
(34).
• Screw the union nut (37) back onto the shaft (34).
• Retighten the union nut (37) firmly. Hold the grinding
disc (12) or polishing wheel (2) that has just been
fitted with one hand to build up the appropriate coun-
ter-pressure.
m WARNING!
- Never operate the grinding disc (12) or polishing
wheel (2) without the protective covers (40).
m Attention!
- Do not tighten the union nut (37) too much, other-
wise the grinding disc (12) could break.
• Refit the protective cover (40) and securely fix it by
tightening the fixing screws (39).
Fitting the flexible shaft (Fig. 1)
• Screw the flexible shaft (5) onto the connection
thread (4) of the device. The inner axis of the flexible
shaft must be pushed into the square recess on the
connection thread (4). Turn the locking nut (3) an-
ti-clockwise to tighten.

Insert tool into the flexible shaft (Fig. 1)
• To lock the spindle, push the black sleeve (6) on the
flexible shaft (5) completely back. Make sure that
the collet holder (7) can be released anti-clockwise.
Hold the black sleeve (6) in this position.
• Use the combination spanner (23) to loosen the
collet holder (7) on the flexible shaft (5).
• Insert the tool and screw the collet holder (7) back
in place.

11. Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains connection as well as the ex-
tension cable used must also comply with these reg-
ulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Pressure points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fixed or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables of the same designation.
The printing of the type designation on the connection
cable is mandatory.
