| Fasteners not firing | Empty magazine, jammed fasteners, pusher rod not fully engaged, incorrect fastener type. | Check fastener supply. Unload and clear any jams (see below). Ensure pusher rod is locked. Verify correct fastener type and size. |
| Fasteners not fully penetrating | Low power setting, hard material, worn driver blade, insufficient pressure on tool. | Switch to 'High' power setting. Apply more firm pressure to the tool. Ensure fasteners are appropriate for material. If issue persists, contact support. |
| Fasteners jamming frequently | Incorrect fastener size/type, bent fasteners, debris in magazine, worn parts. | Unload fasteners and clear jam. Use only genuine Arrow fasteners. Inspect fasteners for damage. Clean magazine channel. |
| Tool feels stiff or difficult to operate | Lack of use, internal debris, spring issue. | Operate the tool a few times without fasteners. Clean the tool. If problem persists, contact customer support. |
Clearing a Jam:
- ALWAYS point the tool away from yourself and others.
- Unload all fasteners from the magazine.
- Carefully inspect the firing channel and magazine for any bent or stuck fasteners.
- Use pliers or a small screwdriver to gently remove any jammed fasteners. Do not force them.
