Do I need to do anything special to operate the nailers in cold temperatures?

The nailers will perform better in temperatures above 32 degrees Fahrenheit. If you plan on using the nailers below 32F they should be warmed up before use (such as placing them in the cab of a truck while driving to work). Fuel cells can be warmed by placing them in an inside coat pocket. Never place the tool or fuel in the vicinity of a fire or an open heating element.
