Introduction
If your Ridgid R175RNE nailer is not driving the nails all the way through whatever it is you're nailing, then either the nailer cylinder or driving blade O-rings may be worn out. Use this guide to replace your driving blade O-rings.
The driving blade O-rings are what allows the driving blade to glide back and forth inside the driving cylinder.
Be warned that the driving blade and cylinder will likely be greasy, so wear gloves if you want to keep your hands clean.
