Is it necessary to adjust the air pressure when changing nails with a steel nail gun?

Steel nail gun uses air pressure to change nails. When changing nails, the air pressure of the nail gun should be reduced to zero, so as to avoid accidental firing of nails by the nail gun and personal injury. There may still be air pressure on the nail gun before the nail is replaced. If the air pressure is not released, nails may be accidentally fired when replacing nails, thus endangering personal safety. Therefore, before replacing nails, the air pressure on the nail gun must be reduced to zero to ensure safety. In addition, the air pressure of the nail gun also needs to be adjusted to a suitable value to ensure the normal use of the nail gun. Too high or too low air pressure will affect the use effect and life of nail gun. If the air pressure is too high, it will not only increase the speed and strength of nail shooting, but also accelerate the wear of nail shooting gun and reduce its life. If the air pressure is too low, the speed and strength of nail shooting will be weakened, and the ideal nail depth cannot be achieved. Therefore, after replacing the nail, it is necessary to readjust the air pressure to a proper value to ensure the normal use effect and life of the nail gun.
