Cutting Blade; Sharpening; The Setting Must Be Approx. 0.7 Mm - Hakki Pilke OH 27 Instructions For Assembly, Operation And Maintenance

- Keep the blade sharp because:
- a sharp blade will cut the tree quicker and with less power;
- a badly blunted blade becomes warm and may lose its pre-stressing, and
thus sharpening it will require a lot more work;
- less cracking between the teeth is formed in a sharp blade.
- Use for example a 6" v-cut barette file for sharpening.
- Keep the original:
tooth form with a
transverse pitch of
max. 5
If the blade has lost its pre-stressing, take it to a professional with expertise in
pre-stressing blades.
