2. To optimize the velocity, make sure the rear velocity adjustment

is backed all the way out. Adjust the Inline Regulator (refer to

Regulator Adjustment) until the marker is shooting at 250 feet per

second over a chronograph.

3. To fine-tune the marker velocity follow the direction on page 9

(refer to Velocity Adjustment)

ADVANCE ADJUSTMENT:

The ZeRO System is a revolutionary combination of the Feather

Striker and a redesign of the Valve Engine. The ZeRO System is

designed to reduce Mechanical Recoil to a minimum by balancing

the output pressure of the Inline Regulator with the timing of the

ZeRO System.

NOTE: The instructions below are for fine-tuning of the ZeRO

System. Do not attempt unless you have a thorough

understanding of the ZeRO System operation.

1. Insert the 3 mm allen wrench into the ZeRO Adjustment Screw

(Z001).

2. Turning Clockwise will tighten the ZeRO Spring to decrease valve

timing. Refer to Step 2 and 3 from above to fine-tune velocity.

NOTE: Decrease valve timing will increase air efficiency but it

will cause an increase in mechanical recoil.

3. Turning Counter-Clockwise will loosen the ZeRO to increase

valve timing. Refer to Step 2 and 3 from above to fine-tune

velocity.

NOTE: Increase valve timing will decrease air efficiency but it

will cause a decrease in mechanical recoil.
