Blades
BLADE
WARNINGS:
- If a blade is damaged (cracked etc), replace both blades.
- Keep blades in sets that are the same width. This will ensure proper drum balance
- Ensure that blades are kept in good condition and correct clearance (0.6-0.8mm) is maintained.
- Ensure that all bolts securing the blades are firmly tightened – check them regularly.
- Always handle blades with protective gloves on.
- Maximum allowable grinding of each side of the blade is 2.5mm.
- Do not use blades that are under 50mm in width.
When working on the blades, the job may be made easier by accessing the blade drum shaft in
order to rotate the blade drum as required. Do this as follows:
1. Remove the 2 bolts (A) securing the blade shaft access cover (B) and remove the cover – this
allows access to the blade shaft so you can rotate the blades
2. Using a suitable spanner (C) on the end of the blade shaft, rotate the shaft as required. The
machine uses 2 blades (D) and 1 anvil plate (E) that is bolted to the machine body.
