How do I handle many custom frame sizes?
The built-in system stores 100+ profile presets. Set nail spacing and placement freely, then recall setups with one touch for fast changeovers.
Will air pressure stay stable during long runs?
A standard 30 L air tank ensures steady supply and consistent driving, reducing jams and broken nails.
What if miter joints show gaps?
Patented auto-leveling corner compression aligns right angles with zero error for tight, gap-free joints.
