Question about Dewalt D51825 Heavy Duty 31 Degree Clipped Head Framing Nailer
Problem you describe is typical of stuck driver or firing valve. Easy to check; remove head and make sure piston moves down cylinder (upon removing head, piston should be at top). Your gun utilizes sliding cylinder instead of moving valve in head. When you pull the trigger the cylinder moves down allowing air pressure to drive piston down. Orings swell overtime which prevents the cylinder from moving/firing. If cylinder does not move down/up, may be time for rebuild kit. Parts are available at dewalt service center or can be ordered from www.toolpartsdirect.com. Good luck
