7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out
after the machine is protected against accidental
starting by pulling the mains plug.
7.1 Changing the sawblade
The sawblade has to meet the technical specification.
Choose a suitable sawblade, according to the cutting
operation and according to the material to be cut.
For high rip cuts:
- use a wide sawblade (e.g. 13mm), coarse teethed.
For narrow curved cuts:
- use a narrow sawblade (e.g. 6mm).
Check sawblade for flaws (cracks, broken teeth, bending)
before installation. Do not use faulty sawblades.
The sawblade teeth must point in cutting direction (down)
Always wear suitable gloves when handling sawblades.
The sawblades may only be changed when the mains plug
is pulled!

Remove blade from upper and lower wheels (K,L) and
from between upper and lower blade guides (M,N).
Remove blade through slot (O) in table.
Guide the new blade through table slot (O) leading with
