If you do not have access to a test manifold to statically set the delivery pressure from your Vigilante™

you may follow the following steps to establish the proper working pressure for your marker. While this

procedure was designed with the Autococker in mind, Steps 2 through 6 apply directly to all other markers that

utilize a second stage regulator.

STEP 1 -

Back the hammer spring adjustment nut out to the minimum setting.

STEP 2 -

Connect your Vigilante™ system to your marker.

STEP 3 -

Turn the delivery pressure on your Vigilante™ down to the "no flow" point. This is achieved

by turning the adjustment nut counter clockwise until the last 3 to 4 threads remain threaded.

STEP 4 -

Connect your pressure source and slowly apply gas to your system.

STEP 5 -

Utilizing a 3/16 hex key, slowly increase your delivery pressure by turning the adjustment nut

clockwise. Cycle your marker and continue to adjust the delivery pressure until you have just

enough pressure to operate the cocking mechanism properly and the marker sounds like it

will propel a ball.

Autococker owners please skip to STEP 7.

STEP 6 -

While shooting over a chronograph, adjust the delivery pressure in 1/4 turn increments until

the desired velocity is attained.

STEP 7 -

For Autocockers, while shooting over the chronograph adjust your delivery pressure until you

can maintain a consistent string in the low 200 fps range. At this point further adjustment will

result in either no increase in velocity or a marked decrease. Once you have reached this

stage you have found the balance between the hammer spring and the chamber pressure in

your marker.

STEP 8 -

After having achieved this balance, utilize your 3/16 hex to adjust the hammer spring tension

on your Autococker to produce the desired velocity.

This tuning procedure illustrates the importance of having a balanced set of springs in your marker.

The gas pressure in the valve chamber represents stored energy just like the coiled springs in the exhaust

valve and hammer portions of your marker. If your hammer spring is too strong for the chamber pressure

applied, excessively long valve cycles will occur resulting in poor gas efficiency. On the other hand, if it too

weak, the exhaust valve will not open fully resulting in low velocity. Having both elements of spring rate and

chamber pressure in balance is critical to the consistent performance of your marker.
