1. To begin reassembly of the Nerve, reinsert the lower assembly from the rear, valve end first. Push
slowly until the valve locator screw hole in the body and the valve location channel in the lower
assembly line completely up. If the valve location channel is not 100% lined up, adjust it left to
right so that it is, preventing binding or misalignment. Insert the valve locator screw and tighten
down with a 5/32" Allen wrench. NOTE: BE ABSOLUTELY SURE THAT THE HOLE IN THE VALVE
BODY POINTS UP WHEN INSTALLING IN THE MARKER BODY.
2. Reinsert Vision eye strip through the hole located below the detent threaded hole. Replace the
Vision eye cover and screw with a .050" Allen wrench. When threading in screw, be certain to
only thread in far enough to hold the eye in place-do not tighten all the way down. Replace Vision
side ball detent.
3. Plug the Vision eye into the upper circuit board, silver teeth side facing towards the marker body.
4. Feed the wiring harness through the top of the grip frame, then pull the harness straight through
and into the battery area of the grip frame so that all slack is pulled into this area. Replace both
grip frame screws, the front with a 1/8" Allen wrench first, then the rear with a 5/32" Allen
wrench.
5. Insert the wiring harness into the plug on the lower circuit board, making sure all wires are tucked
in cleanly. Replace grip and grip screws.
6. Place valve spring over the end of the cupseal.Then take the cupseal and insert shaft first through
the front of the marker, into the firing piston, located in the dead center of the valve body.
7. Place LPR body into the front of the marker body. Provide light pressure on the LPR body as you
thread it in to the marker body with a 3/8" Allen wrench. Replace LPR spring and cap, making
sure the cap is threaded on, but fits loosely. You will adjust it for pressure later.
8. Make sure the bolt is sitting in the bolt carriage with the pin in the small corner of the bolt slot.
(You should be able to hold the carriage and bolt vertically by the carriage and not have the bolt
fall out).
9. Replace the barrel, gas up the marker, and slowly turn the LPR cap in as you cycle the marker
until the marker fires a shot reliably. Chronograph your Nerve, increasing LPR pressure steadily
until you reach velocity. NOTE: YOU MUST CYCLE YOUR MARKER 5-10 SHOTS BETWEEN LPR
ADJUSTMENTS TO REACH THE NEW PRESSURE/VELOCITY SETTING.
REASSEMBLY
To reset the Nerve’s velocity to its original factory settings:
1. Set Dwell to 30 beeps from the bottom.
2. Set vertical regulator pressure to 200-280 psi (with an average of 230psi), dependent on paint
and barrel size.
3. Increase LPR pressure by first unscrewing the LPR cap to the zero pressure point, then begin
tightening the cap in until the marker begins to fire. Continue to tighten LPR cap until preferred
velocity is reached.
