How to Repair Makita Framing Nailers

Makita framing nailers take a lot of abuse, but are designed by manufacturers accordingly. They are tough guns constructed to survive outdoors in harsh working environments, and fabricated to withstand the rigors of repetitive and rapid nailing. Additionally, these nailers function at a higher PSI than smaller guns because of the larger size of the framing nails. This higher pressure can lead to seal problems that necessitate repairs.
