Stuga recommends this blade be changed after 1-2 weeks of cutting - symptoms to determine if the blade needs changing:

  • Awful cutting sound / smell
  • Profile dragging (sizes too short)
  • Brown burnt swarf
  • Smoke coming out of profile end while cutting

...The 500mm blade is sharp and can be awkward to manouver out of the saw, please be careful

Use protective handwear

Step 4 - Remove Fastening

Once the bolt is loose; remove the bolt, washer and plate.

...Remember which order they are in, as this is the order they must go back on.

Now carefully remove the blade, with this blade being 500mm it will be tight. Ensure you take note of which way the blade spins.

...The blade cutting direction at the top is towards the rear of the machine

Fit the new blade ensuring the teeth are facing the same way it was removed
