Why is my Hitachi NV 45AB2 Nail Gun not driving nails properly?
If your Hitachi Nail Gun operates, but no nail is driven, you can try the following: Clear any jams. Clean and lubricate the nailer. Ensure you are using only recommended nails.
What to do if my Hitachi NV 45AB2 is skipping nails?
If your Hitachi Nail Gun is skipping nails or has an intermittent feed, ensure that you are using only recommended nails. Clean and lubricate the tool, using Hitachi pneumatic tool lubricant. Adjust the nail holder to the proper position. If the piston O-ring is cut or heavily worn, contact Hitachi for replacement.
What to do if Hitachi Nail Gun nails jam?
To prevent nails from jamming in your Hitachi Nail Gun, ensure you are using the specified nails. Remove any abnormal nails, such as those with heads that are too large or too small, or those with abnormal collating wires, and reload the nailer with proper nails. Also, remove any foreign matter from the feed piston chamber. If the nail feeding is incomplete, replace the abnormal part.
Why is my Hitachi Nail Gun not driving nails completely?
If your Hitachi Nail Gun is not driving nails completely, so the heads cannot be made flush with the workpiece, first, set the adjuster to the optimum position. If this doesn't solve the issue, adjust the air pressure to between 4.9 and 8.3 bar (5-8.5 kgf/cm2, 70-120 psi). If the workpiece is too hard, the nailer cannot be used because the material is beyond its applicable range. Also, replace any abnormal parts such as a worn driver blade, a worn or damaged piston O-ring, a cylinder with an abnormal inside surface, or a worn or damaged cylinder O-ring. Apply grease if there is a shortage of oil on both inside and outside surfaces of the cylinder, or if the exhaust valve is abnormal or short of oil.
What to do if my Hitachi Nail Gun is driving nails too deep?
If your Hitachi Nail Gun is driving nails too deep, reduce the air pressure, adjusting it within the range of 70 – 120 psi (4.9 – 8.3 bar 5 – 8.5 kgf/cm2). You may also need to readjust the tool.
Why are nails jamming and bending in my Hitachi NV 45AB2?
If nails are jamming or the driven nail is bent when using your Hitachi Nail Gun, make sure you are using only recommended nails. Also, if the driver blade is worn, contact Hitachi for a replacement.
What to do if Hitachi NV 45AB2 Nail Gun doesn't drive fully at faster nailing speeds?
If your Hitachi Nail Gun drives properly during normal operation but does not drive fully at faster nailing speeds, use a larger air hose.
Why does my Hitachi Nail Gun drive nails bent?
If nails are being driven bent by your Hitachi Nail Gun, it may be because the nails are not completely fed into the injection port, or unspecified nails are being used. Also, a worn driver blade could be the cause, so replace the part. If the workpiece is too hard, the nailer cannot be used because the material is beyond its applicable range.
What to do if my Hitachi NV 45AB2 has a weak drive and is slow to cycle?
If your Hitachi Nail Gun exhibits a weak drive or cycles slowly, try the following: Increase the air pressure, but do not exceed 120 psi (8.3 bar 8.5 kgf/cm2). Readjust the tool. Use Hitachi pneumatic tool lubricant. If the driver blade is worn, contact Hitachi for a replacement. Also, check if the piston O-ring is worn or damaged.
