Identifying the Issue

Before starting any repair, it’s essential to diagnose the problem with your Makita nail gun. Common issues may include:

Basic Troubleshooting

1. Jammed Nails: If nails are jammed, open the magazine and remove the jammed nails. Ensure the nails you use are of the correct size and quality.
