- Fastener Path Inspection: Regularly inspect the fastener path for any obstructions or damage.
- Air Filter: Check and clean the air filter on your compressor regularly to ensure clean air supply to the tool.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool not firing or weak firing | Low air pressure; Insufficient air volume; Fastener jam; Worn O-rings. | Check air compressor pressure (ensure 70-90 PSI); Use a larger air hose; Clear any fastener jams; Lubricate tool or replace O-rings if necessary. |
| Fasteners not fully driven | Low air pressure; Incorrect striking force; Wrong fastener length for material. | Increase air pressure; Ensure a firm, direct strike with the mallet; Verify fastener length is appropriate for flooring thickness. |
| Fastener jams frequently | Incorrect fasteners; Damaged fasteners; Debris in magazine; Worn driver blade. | Use only specified fasteners; Inspect fasteners for damage before loading; Clean magazine and nosepiece; Contact service for driver blade replacement. |
