Fitting diamond cutting discs

To change tools, the upper protective guard (17) must be swivelled all the way out. Place the power tool on a solid surface.
Open the power tool by pressing the release button (20). Open the upper protective guard (17) using the buckle (1).

  • Before carrying out any work on the power tool (e.g. maintenance, tool change etc.), remove the battery from the power tool. There is risk of injury from unintentionally pressing the on/off switch.

Press the spindle lock button (10) to lock the grinding spindle.

  • Do not press the spindle lock button while the grinding spindle is moving. The power tool may become damaged if you do this.
  • When using the clamping nut (27): Loosen the clamping nut with a two-pin spanner (28).
  • When using the quick-clamping nut with bar (25): Fold up the bar and turn the quick-clamping nut (25) firmly anticlockwise. Use a two-hole spanner to loosen a tight quick-clamping nut.
  • When using the quick-clamping nut (26): Turn the knurled ring anticlockwise. Use a two-hole spanner to loosen a tight quick-clamping nut.

Remove the spacer discs (24) and the mounting flange (22). Clean the grinding spindle (21) and all the parts to be fitted.

The groove width is determined by the number of spacer discs (24) between the two diamond cutting discs (23) and the thickness of the diamond cutting discs.

The groove width is calculated as follows:
Groove width = thickness of the spacer discs + thickness of the diamond cutting discs.

The permissible groove width can be found in the “Technical Data” section see Technical Data.

You may use the power tool with one or two diamond cutting discs.

Place the mounting flange (22) on the grinding spindle (21). The mounting flange must sit with its drive collar positioned correctly on the grinding spindle.

Place the diamond cutting disc (23) and the spacer discs (24) on the mounting flange (22).

  • All of the supplied spacer discs must always be fitted, irrespective of the groove width required. Otherwise, the diamond cutting disc (23) could come loose during operation and cause injury.

Number of spacer discs required:
4 discs of 6 mm thickness
3 discs of 4 mm thickness

At least one spacer disc (24) must be fitted between two diamond cutting discs (23).

Note: Only diamond cutting discs may be used. The use of bonded reinforced cutting discs is not permitted!

When fitting the diamond cutting discs, make sure that the direction of rotation arrows on the diamond cutting discs and the direction of rotation of the power tool (see direction of rotation arrow (29) on the upper protective guard) match.

Press the spindle lock button (10) to lock the grinding spindle.

  • When using the clamping nut (27): Screw on the clamping nut and tighten it with the two-pin spanner (28).
  • When using the quick-clamping nut with bar (25): 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.
  • When using the quick-clamping nut (26): Unscrew the quick-clamping nut and turn the cutting disc firmly clockwise.

Lock the upper protective guard (17) with the buckle (1). Then swivel the upper protective guard inwards until the release mechanism (20) audibly clicks into place.

When working with two diamond cutting discs (23), always replace them in pairs.

See the graphics page for the order of assembly.

There are three markings to indicate the positions of the diamond cutting discs (13).

  • Internal marking: Indicates the position of the internal diamond cutting disc (23) if no spacer disc (24) is inserted between the mounting flange (22) and this diamond cutting disc.
  • Centre marking: Indicates the geometric centre between the internal and external diamond cutting disc.
  • External marking: Shows the position of the external diamond cutting disc (23) if this diamond cutting disc is placed on the very outside, i.e. no more spacer discs (24) are inserted beyond this.
