Lesson steps

Marker will not turn on

Check battery charge and orientation, battery contacts, the board connector, and any tournament lock or safe mode before suspecting the board.

Marker will not fire

Confirm it is gassed, safety off, eyes reading a ball or eyes bypassed, trigger activation point set, and the bolt is installed correctly.

Air leaking from the marker

Isolate the leak: down the barrel usually means a bolt or valve seal; from the grip usually means the solenoid or hose; at the tank means the tank o-ring. Degas before touching anything.

Chopping paint

Usually a slow loader, dirty or misaligned eyes, worn detents, or brittle paint. Clean the eyes and replace detents first.

Inconsistent velocity

Check tank output, regulator creep, low battery, bore mismatch, and wet or swollen paint. Chrono over a string of shots, not one.

Loader not feeding

Check loader batteries, drive cone or paddles, feedneck clamp tightness, and the loader lid seating.

Eyes not detecting paint

Wipe the lenses, check the eye wires for pinches, and verify eye covers are seated. Only bypass eyes as a temporary field measure.

Stop immediately if the tank, regulator, or high-pressure system appears damaged

Cracks, dents in composite wrap, a spinning regulator, hissing at the burst disc, or an expired hydro date all mean stop, degas, and retire the item to a professional.

Safety warning

Stop immediately if the tank, regulator, or any high-pressure component looks damaged. Degas, remove the air source, and have a qualified airsmith handle it — do not attempt a field repair.
