# Changing the sanding sheet

Remove dirt and dust from the sanding plate (3), e.g. with a brush, before attaching a new sanding sheet.

To ensure optimum dust extraction, make sure that the punched holes in the sanding sheet are aligned with the drilled holes in the sanding plate.

## Sanding sheets without hook-and-loop backing (see figures B–D)

❶ | Unlock both sanding-sheet clamps (4) and swivel them downwards.
❷ | Insert the sanding sheet (6) under the rear clamping bracket (2). Ensure that the sanding sheet (6) is not too short and that it is correctly clamped. Swivel the sanding-sheet clamp (4) back into the starting position and lock it in place.
❸ | Position the sanding paper so that it fits tightly around the sanding plate (3). Clamp the front part of the sanding sheet under the front clamping bracket (7). Ensure that the sanding sheet (6) is not too short and that it is correctly clamped. Swivel the sanding-sheet clamp (4) back into the starting position and lock it in place.

Unperforated sanding sheets, e.g. from rolls or bulk stock sold by the metre, can be perforated using the punch (17) for the purpose of dust extraction. To do this, fit the sanding sheet on the power tool and push the tool down onto the punch (see figure F).

To remove the sanding sheet (6), unlock both sanding-sheet clamps (4) and pull the sanding sheet out of its bracket.

## Selecting a sanding sheet

Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:

| Grit
--- | ---
For processing all wood and wood-based materials | 40–180
For pre-sanding, e.g. of rough and uneven beams and boards | Coarse | 40
For surface sanding and levelling of slight irregularities | Medium | 80, 120
For finish-sanding and fine sanding of hardwoods | Fine | 180
For processing paint and lacquer layers or primers such as fillers and bodyfillers | 40–180
For sanding down paint | Coarse | 40
For sanding undercoats | Medium | 80, 120
For final sanding of primers prior to painting | Fine | 180

For any finishing work, such as polishing (metal and stone in particular), use fleece/polishing felt.

Different types of fleece and polishing felts should be used depending on the surface finish required on the workpiece.
