Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Nail gun does not fire. | No air pressure; no nails in magazine; safety mechanism not engaged; jammed fastener. | Check air supply and pressure; load nails; ensure contact trip is fully depressed; clear jam (disconnect air first). |
| Nails not driven to full depth. | Low air pressure; depth adjustment set too shallow; incorrect nail size. | Increase air pressure; adjust depth setting; ensure correct nail length and gauge. |
| Nail gun jams frequently. | Incorrect nails; worn driver blade; debris in magazine; insufficient lubrication. | Use recommended nails; inspect/replace driver blade; clean magazine; lubricate tool. |
| Air leaks from tool. | Loose fittings; worn O-rings/seals. | Tighten connections; replace worn seals. |
