Introduction
If your Ridgid R175RNE nailer is firing nails off target, or not at all, you may need to replace its driving blade. Follow this guide to learn how to do so.
The driving blade is what fires the nails in the nailer, and is situated inside the driving cylinder.
As noted in Step 2, be sure to remember which way the plastic collar on the driving cylinder is placed. It is not snug, and can fall off.
