The adjustable coil magazine holds 250–400 nails, allowing the tool to accommodate different compatible coil configurations while reducing reload frequency during production work.
The listed tool-free depth control allows operators to adjust fastener drive depth for different siding, sheathing and wood fastening applications.
The adjustable exhaust can be positioned to direct discharge air away from the operator and work surface.
The integrated rafter hook provides a convenient way to hang the tool when it is not being used.
The CN55 uses an aluminum body and a heavy-duty driver configuration for professional fastening work. The listed tool weight is 2.88kg.
The current product information lists a firing capability of up to 10 nails per second for high-volume fastening applications.
CN55 is specified for 15° flat wire collated coil nails from 1¼" to 2¼" (32–57mm) in length and .083"–.099" (2.1–2.5mm) in shank diameter.
Compatible shank configurations include smooth, ring and screw shank. Always confirm the complete nail dimensions, head size, collation and finish before loading the tool.
The KYA CN55 specification is not identical to every similarly named coil nailer. For example, the current MAX CN55 specification lists a narrower .083"–.092" shank range, so fasteners and replacement parts should be matched to the exact tool model rather than assumed interchangeable.
Fiber cement siding – suitable exterior wall fastening
Fencing – wood and compatible composite assemblies
Decking – compatible deck, subfloor and joist fastening
Sheathing – plywood and OSB
Pallet and crate – industrial wood packaging and assembly
| Symptom | Possible Cause | Suggested Check |
|---|---|---|
| Air leak at cap | Loose or worn O-ring | Inspect and replace the head valve O-ring if required. |
| Weak drive | Low air pressure or worn piston | Check operating pressure and inspect the piston O-ring. |
| Nail jam | Bent driver or incorrect fasteners | Inspect the driver and use the specified 15° .083"–.099" coil nails. |
| Tool does not fire | Trigger obstruction or insufficient air pressure | Inspect the trigger and confirm air pressure is within 70–120 PSI. |
