Another cause of nail gun malfunction is air leaks, causing the tool to only blow air without properly driving nails into the wood. While many air leaks can be resolved independently, more significant issues may necessitate the assistance of an expert nail gun repair facility.
An air leak in a nail gun can result from several factors, including:
Excessive trigger activation can cause it to loosen and allow air to escape, while worn O-rings, typically made of rubber, can fail to cover the exhaust opening, resulting in air supply leakage.
Type of Air Leaks
Air Leaks Through the Exhaust Vent
Air leakage in exhaust openings or back exhaust channels is often caused by worn components, allowing air supply to go through. O-rings, made of rubber or synthetic materials, are designed to seal surrounding the valve and prevent air leakage, ensuring proper operation.
To address this issue, it’s recommended to obtain a manufacturer-provided replacement kit, ensuring compatibility with your nail gun model for a correct and effective for replacing the O-ring.
Air Leaks Through the Trigger
Trigger valve pressure issues often result from wear caused by repeated trigger pulls. To resolve this, acquire a replacement valve according to the manufacturer’s instructions. This issue is distinct from sensations experienced during nail firing.
If it appears that nothing is working, a faulty valve may be the root cause, and replacing it could address the problem with the valve not cycling properly.
How To Fix
- Adjust the nail gun’s air pressure according to the user manual.
- Disassemble the nail gun to inspect the compressor for any damage.
