# Fitting the Abrasive Tools

- Pull the plug out of the socket before carrying out any work on the power tool.

- Do not touch grinding and cutting discs until they have cooled down. The discs can become very hot while working.

Clean the grinding spindle (17) and all the parts to be fitted.

Lock the grinding spindle with the spindle lock button (1) before clamping and releasing the abrasive tools.

- Do not press the spindle lock button while the grinding spindle is moving. The power tool may become damaged 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, make sure that the direction of rotation arrow on the diamond cutting disc corresponds to the direction of rotation of the machine (see direction of rotation arrow on the housing).

See the graphics page for fitting instructions.

Note: When assembling bonded grinding or cutting discs using the supplied mounting flange (9) and the clamping nut (13) or quick-clamping nut (14), the use of intermediate layers is not necessary.

To secure the grinding/cutting disc, place the mounting flange with O-ring (9) on the grinding spindle (17) and screw on the clamping nut (13). Ensure the alignment of the clamping nut (13) depending on the grinding/cutting disc used (see figures in the front part of the operating manual), and tighten them with the two-pin spanner see Quick-clamping nut .

- After fitting the abrasive tool, check that the abrasive tool is fitted correctly and can turn freely before switching on the power tool. Make sure that the abrasive tool does not brush against the protective guard or other parts.

A plastic part (O-ring) is fitted around the centring collar in the mounting flange (9). If the O-ring is missing or damaged, the mounting flange (9) must be replaced before operation can resume.
