Alignment of the Blade
When positioning the new blade on the arbor, make sure the teeth are facing in the right direction. For most circular saws, the teeth should point down, towards the base plate, as this is the direction of feed.
Securing the Arbor Nut
Once the blade is securely in place, you can reattach the arbor nut. Tighten it by turning it clockwise, ensuring it’s snug but not overly tight, as this might damage the blade.
Step 6: Final Checks and Reassembly
Release the Blade Lock
After securing the blade, press the blade lock button or lever again to release it.
Check Blade Security
Gently wiggle the blade with your hand to ensure it is securely locked in place. There should be no loose play.
Step 7: Test the Circular Saw
