Why does my DeWalt D51238 Nail Gun lack power?
- VVictor VargasAug 18, 2025
If your DeWalt Nail Gun is lacking power or seems sluggish, several factors could be responsible: * Low air pressure: Check the air supply. * Lack of lubrication: Lubricate the tool using approved pneumatic tool oil. * Damaged or worn O-rings: Replace the gasket/O-rings using the O-ring Repair Kit, Cat # D512381. * Blocked exhaust port: Disconnect the air, remove the exhaust plate from the top of the tool, and clean the port.
