Questions & Answers for Ridgid R4120

How to change the Blade?
Rick for model number R4120 asked on 2023-10-25
Hi Rick, Thank you for your question. To change the blade, start by removing the blade guard, then press the blade locking pin and turn the blade until it can no longer move. Use an Allen wrench to remove the blade bolt and then the flange. Place the new blade in and then replace the flange and bolt. Lower the guard mounting hardware and tighten the screw back into place. We hope this helps!
