Taken from the factory's own service and troubleshooting guidance.
Pneumatic nailers and staplers (brad, finish, concrete, coil, framing, flooring, pin, palm, fencing, upholstery and insulation tools), cordless 20V nail guns, air and cordless compressors, air tools, hoses and fittings, and nails — 198 models in the current catalogue.
DAJ for professional pneumatic nailers, and FREEMAN, created through the company's US branch, for compressors, cordless nail guns and air tools. The NUMAX brand was also created there.
In the Mechanical & Electrical Park of Wenling Industrial City, Taizhou, Zhejiang, China — where the company moved in 2005. Its integrated production base covers 50,000 m².
Each model lists its working pressure, for example AF30 60–115 psi (4–8 bar), XAGD 50/9040/T50 60–110 psi and ST64/T50 70–115 psi. If a tool operates sluggishly, make sure the compressor is set between 60 and 100 PSI.
Keep it clean and lubricated: add 2–3 drops of lubricant into the air connector, use only manufacturer-identified accessories and lubricants, and have service done by qualified repair personnel.
Typical causes are a worn driver channel, a broken or worn piston, bent or wrong fasteners, or a dirty or loose magazine. Disconnect the air hose and remove remaining fasteners before clearing a jam.
The ISO 9001 system was introduced in 2000–2002. Honors include National High-tech Enterprise, a Torch Plan Project Certificate, a Zhejiang provincial High-tech Enterprise R&D Center and the 2021 Wenling Municipal Government Quality Award.
