# Fitting the Abrasive Tools

- Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

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

Clean the grinding spindle (22) and all the parts to be fitted.

Lock the grinding spindle with the spindle lock button (2) 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

- To secure a grinding/cutting disc, use the clamping nut (18) or the quick-clamping nut with bar (19).

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.

Use the quick-clamping nut (19) to secure the grinding/cutting disc without the need for additional tools.

- The quick-clamping nut (19) may be used only for grinding or cutting discs.

- Only use quick-clamping nuts (19) that are in good working order and not damaged.

- When screwing on, make sure that the printed side of the quick-clamping nut (19) is not facing the grinding disc.

Press the spindle lock button (2) to lock the grinding spindle. To tighten the quick-clamping nut (19), fold up the bar and turn the quick-clamping nut firmly clockwise. Then fold down the bar to secure the quick-clamping nut. It is not sufficient to tighten the disc along the edge.

Quick-clamping nuts (19) that are properly secured and not damaged can be removed by hand. To do this, fold up the bar and turn the quick-clamping nut firmly anticlockwise. If the quick-clamping nut is stuck, do not attempt to loosen it with a tool – always use a two-pin spanner.

After fitting the hub flange and the grinding/cutting disc, the free thread length of the grinding spindle must be at least 4 mm.

Ensure that the abrasive tool is firmly seated, so that it does not twist away from the spindle in the runout of the power tool.

A plastic part (O-ring) is fitted around the centring collar in the hub flange (14). If the O-ring is missing or damaged, the hub flange (14) must be replaced before operation can resume.

- 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.

Assembly with Clamping Nut (18)

(UniversalGrind 18V-75)

Pay attention to the dimensions of the grinding tools. The mounting hole diameter must fit the mounting flange without play. Do not use reducers or adapters.

When using diamond cutting discs, pay attention that the direction-of-rotation arrow on the diamond cutting disc and the direction of rotation of the machine (see direction-of-rotation arrow on the machine head) agree.

See graphics page for the mounting sequence.

To fasten the grinding/cutting disc, screw on the clamping nut (18) and tighten with the two-hole spanner.

- 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.
