Tighten all of the screws on the nail gun. Loose screws can cause air leaks, which cause the gun to lose driving power and functionality.
Lubricate the nail gun using Ryobi's provided nail gun lubricant. Lubricant will help the nail gun operate smoothly, quickly and without jams. If you don't own or cannot locate the provided lubricant, most home improvement stores sell replacement nail gun lubricant.
Install new fasteners. Improperly sized or overused fasteners will cause your nail gun to jam. Jams may cause injury or further mechanical problems in your Ryobi gun.
