Understanding Your Bostitch Finish Nail Gun

Before diving into repair, let’s get acquainted with the Bostitch finish nail gun’s essential components:

1. Nail Magazine: The magazine stores nails and feeds them into the firing chamber.

2. Trigger: Pulling the trigger activates the firing mechanism.

3. Firing Mechanism: This includes the piston, driver blade, and other components responsible for driving the nail into the workpiece.

4. Air Supply: Most Bostitch finish nail guns are pneumatic, requiring a compressor to supply compressed air for operation.

Now, let’s tackle some common issues and their solutions.

Potential Causes:

• Insufficient Air Pressure: Ensure your compressor is delivering adequate air pressure (usually around 90 PSI).
• Jam in the Magazine: Clear any nail jams from the magazine.
• Worn or Damaged Trigger Valve: Replace the trigger valve if it’s damaged.

Nails Don’t Sink Properly

Potential Causes:

• Incorrect Nail Depth Setting: Adjust the nail depth setting on the gun.
