Electric carpet nail guns and electric staplers rely on internal springs for firing power and rebound. The GO-210-4 conical spring is a core component of the drive mechanism; spring fatigue significantly degrades equipment performance

After several years of high-frequency use, metal fatigue causes spring force to decrease. Typical malfunctions include: weak nail gun firing, staples not fully driven in, frequent nail jamming, and inability to reset properly

Spring aging not only affects work efficiency but also increases the motor load. Replacing the spring restores the nail gun's original firing power and extends the lifespan of the motor and drive mechanism

The conical design is a core advantage of this product. The spring has different diameters at both ends, resulting in a gradual increase in spring force during compression, rather than a sudden burst. This makes the firing action more controllable and reduces impact on the internal structure of the equipment

During installation, open the nail gun housing and locate the spring mounting position below the drive post or firing lever. Remove the old spring and install the new spring in the same direction, ensuring both ends are properly seated. Note that the spring should not be installed backwards
