# Fitting the abrasive tools (see figure A)

- Only use open-ended spanners that are suitable and undamaged (see "Technical Data").

- Only use brand accessories for grinding from the dealer for the power tool which are approved for a minimum speed of 16,000 min–1, which have a maximum diameter of 50 mm and are held by a backing pad, which also has a maximum diameter of 50 mm and which has a straight shank with a diameter of 6 mm, 1/4" or 8 mm.

- Clean the grinding spindle (9) and all the parts to be fitted.
- To release the collet (16), push the spindle lock (8) forwards.
- Loosen the clamping nut (10) by placing an open-ended spanner (14) on the spanner flat and turning it anticlockwise.
- Insert the straight shank of the backing pad (11) all the way into the collet (16).
- Firmly clamp the backing pad (11) by turning the clamping nut (10) clockwise with the open-ended spanner (14).
- Fit the disc (12) on the backing pad (11).
- Then push the spindle lock (8) back again.

The grinding tools must run completely concentrically. Do not continue to use damaged grinding tools that are out of balance. If the grinding tools are out of balance, they should be replaced.

- Do not, under any circumstances, tighten the collet with the clamping nut until a grinding tool has been fitted. The collet may otherwise become damaged.

- Only use backing pads with an appropriate shank diameter. A backing pad with a shank diameter which does not correspond to the tool holder of the power tool (see "Technical Data") cannot be held properly and will damage the collet chuck.

- The application tool must be clamped at least 10 mm. The inner shank dimension L0 can be used to calculate the maximum permitted speed of the application tool from the specifications provided by the manufacturer of the application tool. It must not be less than the maximum speed of the power tool.
