ADVANCE ADJUSTMENT:
The ZeRO System is a revolutionary combination of the Feather
Striker and a redesigning of the Valve Engine. The ZeRO System is
designed to reduce Mechanical Recoil to a minimum by balancing
the output pressure of the lnline Regulator with the timing of the
ZeRO System.
NOTE: The instructions below are for ne-tuning of the
ZeRO System. Do not attempt unless you have a thorough
understanding of the ZeRO System operation.
1. Insert the 3mm allen wrench into the ZeRO Adjustment Screw (Z031).
2. Turning Clockwise will tighten the ZeRO Spring to decrease valve
timing. Refer to Step 2 and 3 from above to ne-ture velocity.
NOTE: Decrease valve timing will increase air efciency
but it will cause an increase in mechanical recoil.
3. Turning Counter-Clockwise will lossen the ZeRO to increase
valve timing. Refer to Step 2 and 3 from above to ne-turn velocity.
NOTE: Increase valve timing will decrease air efciency
but it will cause a decrease in mechanical recoil.
ASSEMBLY AND CLEANING
WARNING: Never remove the internals of the marker while
the air tank is attached with the marker. Always remove
all paintballs, loader and air tank before disassembling
the marker.
CLEANING AND DISASSEMBLE REAR INTERNALS
1. Lift upward on the Top Cocking Knob at the rear of Delrin Bolt.
This will let the Delrin Bolt (P041) slide out from the rear of the
receiver.
2. Turn the End Cap (A051) counterclockwise. This will let the End
Cap (A051) and the marker’s internals to slide out from the
rear of the receiver. Remember to place the marker in the
de-cock position and place light pressure behind the End Cap
during the removal of the End Cap, this way will prevent the
internals to spring out.
3. Slide the Feather Striker (P021) out of the rear of the receiver.
4. Once all the internal parts are removed, use a squeegee to clean
the inside of the receiver and use a towel to clean the dirt or
paint of Delrin bolt. Apply some paintball gun oil on the Striker
O-Ring regularly.
REASSEMBLE REAR INTERNALS
1. Insert the Feather Striker (P021) thru the rear of the receiver
with the O-Ring facing towards the front of the marker and
with the hole on the Feather Striker facing upright. While
inserting the Feather Striker, apply pressure behind the Feather
Striker and at the same time pull the Trigger to let Feather
Striker enter the rear chamber of the receiver.
2. Insert the Feather Bumper (P024) thru the receiver and insert
the Feather Spring (P022) thru the Feather Bumper.
3. Insert the End Cap (A017) with the Velocity Adjuster (P023)
thru the Feather Bumper and Feather Spring.
4. Turn the End Cap (A051) colckwise to tighten it and hold the
internals in place.
5. Insert the Bolt Assembly (P041) thru the rear of the receiver.
Press downward on the Top Cocking Knob (At the rear of Bolt
Assembly) to connect and enter the hole of Feather Striker to
fasten with the Feather Striker. Use a small tool such as allen
wrench to align the hole of the Feather Striker.
