Please note Low strength Loctite should be used on the thread from piston to head.

1. A long 3mm Allen key is used to adjust the Accu-Port.
2. From new the port will be adjusted to the closed /off position which will not allow any air through.
3. Releasing the Allen key will release air and allow tuning of the volume.
4. Best performance is most likely to be within the range of 3-5 full turns from the off position.
5. Once tuned and set, a low strength Loctite should be used on the adjuster thread to ensure it doesn’t self adjust when firing.
