Step 5: Install the New Circular Saw Blade
Position your new circular saw blade in the correct direction. Most saw blades have arrows indicating the rotation direction; ensure this aligns with the design of your saw. Slide the blade onto the spindle, making sure it fits snugly.
Tip:
When installing, double-check that the blade teeth are positioned correctly. This is crucial for effective cutting.
Step 6: Secure the Blade Bolt
Replace the blade bolt and tighten it using your wrench. Ensure it is firmly secured but take care not to overtighten, as this could damage the blade or the saw’s spindle.
Step 7: Double-Check Everything
Before reattaching the battery and starting the saw, take a moment to inspect your installation again. Check if the blade is seated correctly, the bolt is tightened, and there are no loose components.
Step 8: Perform a Test Cut
Once everything is secured, reattach the battery. Choose a scrap piece of wood to perform a test cut. This initial cut will help you confirm that the blade is installed correctly and that your saw functions properly.
Tip:
Always start with a light cut and monitor the performance. If any issues arise, turn off the saw immediately.
