# Changing the HSS Planer Blades

- Take care when changing the planer blade. Do not pick up the planer blade by the cutting edges. You may be injured by the sharp cutting edges.

##

- To replace the planer blades, turn the blade head (16) until the clamping jaw (15) is parallel with the planer base plate (11).
- Unscrew the three fastening screws (14) with the T-handle socket spanner (13) and remove the clamping jaw (15).
- Push the retaining clip (19) together with the planer blade (18) out of the blade head (16) and/or the guide groove (17).
- Turn the blade head 180° and remove the second planer blade.

Note: Before changing or resharpening the planer blades, remove the retaining clip (19) by undoing the fastening screw (20).

##

Worn or blunt HSS planer blades can be resharpened using the sharpening aid (21) (accessory) and a commercially available grinding stone.

Place both planer blades in the sharpening aid and clamp them firmly with the wing bolt. Make sure that both planer blades are pushed in fully.

Move the planer blades placed in the sharpening aid steadily across the grinding stone, applying light pressure.

Note: The planer blades must not be resharpened by more than 6 mm (i.e. to a minimum width of 23 mm). Both planer blades must be replaced when they reach this size.

##

Before (re)inserting new or resharpened planer blades, clean the blade head (16) and, if necessary, the planer blade (18) and the retaining clip (19). Clean heavily gummed planer blades with spirits or petroleum.

Note: New and resharpened planer blades must always be set to the correct height before fitting.

The setting gauge (22) (accessory) is used to adjust the height of the planer blades. Place the planer blade (18) and the retaining clip (19) on the setting gauge. Make sure that the blade retainer (19) engages in the groove intended for this purpose. Press the planer blade (18) against the guide and fix the retaining clip (19) in this position with the fastening screw (20). This will automatically adjust the correct height.

The planer blade must be fitted and aligned with the centre of the planer base plate (11). Then tighten the three fastening screws (14) with the T-handle socket spanner (13). Ensure that the tightening sequence (①②③) on the clamping jaw (15) is followed correctly.

Note: Check that the fastening screws (14) are firmly tightened before start-up. Turn the blade head (16) by hand and ensure that the planer blades are not brushing against anything.
