1. Nailing: Hold the fixed elastic sheet of the nail pusher, pull out the nail pusher, put the sealed nail into the slot seat with the nail tip down, slowly push in the nail pusher and buckle the fixed elastic sheet into the slot seat. The direction of pushing the nail block should be the same as the nail.
2. Clamping nails: adjust the clamping tightness and adjust the nut. The clamping nails are looser clockwise and tighter counterclockwise. Tighten the adjusting nut after the tightness is moderate.
