CHARGING OR USING YOUR AIRGUN
To access the tuner, the action of your air gun must be fully open. At that point two
windows on the left side of the frame will align, allowing access to the tuner.
The force of the striker can be adjusted so that there is just enough force to open
the valve, eliminating excess wear and recoil. This also has shown accuracy
improvements. Except for the lightest pellets, once the valve is cracked open, the
valve will self regulate to the weight of the projectile used. This is partially due to
the fact that heavier pellets have more contact to the bore and move slower out of
the bore.The resulting pressure on the valve, holds it open longer. Very light-weight
pellets are the exception as they may not hold the valve open long enough to achieve
maximum velocities. Starting at a lower tank pressure (i.e. 2700 p.s.i.) may help to
achieve maximum accuracy with these light pellets.
To increase tuner tension rotate it downwards, to decrease tension rotate it upwards.
Increasing tension can help achieve higher velocities for light-weight pellets.
Note: Position marks are only to help the shooter nd and repeat settings when the
rie is tuned for a specic projectile.
