Using the 5mm Allen wrench correctly guarantees a smooth and safe blade change on your DeWalt circular saw, preventing damage to the screw and keeping your tool in good working condition.
Remove the Washer to Access the Blade
Once you’ve loosened the screw using the Allen wrench, carefully pull off the washer from the spindle. The washer sits between the blade and the screw, so removing it gives you access to the blade.
Handle it gently to avoid dropping or damaging it as you proceed.
Loosen Screw First
How do you gain access to the blade on your DeWalt circular saw? First, you need to loosen the screw that holds the washer and blade in place. Use the 5mm Allen wrench to turn the screw clockwise until it’s fully loosened. Don’t rush this step—make sure the screw is completely loose before moving on.
Once loosened, carefully remove the washer from the spindle. Keep track of this washer because you’ll need to reinstall it correctly when you put the blade back on. Loosening the screw fully lets you remove or replace the blade without damage or difficulty. Taking your time here ensures a smooth blade change and keeps your saw in good working order.
Use Allen Wrench
After loosening the screw with the 5mm Allen wrench, you’ll need to remove the washer to access the blade. Use the wrench to turn the screw clockwise until it’s fully unscrewed from the spindle. Once the screw is out, carefully pull the washer off the spindle. Make certain the washer is completely removed so you can reach the blade and spindle area without obstruction.
Handle the washer gently to avoid dropping or damaging it during this step. Keep the washer in a safe spot where it won’t get lost or dirty, as you’ll need it later when reassembling the new blade. Taking these precautions ensures a smooth blade change and helps maintain your saw’s performance.
Remove Washer Carefully
Though the screw is loosened, you’ll need to pull the washer away from the spindle gently to avoid any damage. Handle the washer with care to prevent bending or scratching it, which could affect its fit later. Keep track of the washer to avoid losing it during blade replacement. When reinstalling, remember the beveled edge must face outward for safety and proper fit. Removing the washer correctly gives you clear access to the blade, making your job easier and safer.
