There are three different ways to adjust the Emag/Xmag trigger, pull weight, pull length, and how soon the pull is recognized. The Emag/Xmag trigger is magnetic so with no mircoswitch, there is almost no limit to how heavy or light you can make your pull. With the three adjustment points together, you can truly get the pull you desire from a marker.
To adjust the trigger, you must first remove the trigger frame and battery from the rest of the marker. After degassing, there is three screws that need to be removed, the valve field strip screw, the front frame screw, and the sear axle pin(on the left side of the rail for Emag / left side of Body for Xmag). you can remove all three screws using a 1/8 allen wrench.
To test your pull, hook up the battery and turn on the frame. Slightly lift the back of the sear with your finger and pull. The pic shows the marker in mechanical mode but to test your trigger for reliability you will need it in electric mode. (Use this method if your firmware does not have a trigger test feature.)
The first step is to get a pull weight that you are happy with. To adjust the weight, remove the magnets from the frame so you can determine your starting point. If you want a heavier pull, simply add more magnets(AGD uses earth magnets) or remove any shims that may be in use. If you want a lighter pull, either remove magnets until there is only one left, and/or use something not metallic(o'ring, paper, etc.) as a shim to increase the distance between the magnet in the frame and the magnet in the top of the trigger. On the Xmag, the magnets are located under the ace board, simply unscrew the board to get in there. (this adjustment is only for electric mode)
The easiest way to remove a magnet from the frame is to put the marker in mechanical mode, pull the trigger back and use an allen wrench to attract the magnet from the frame.
The next step is to adjust the pull length. Make sure the selector switch lever is in the E(6 o'clock) position. Using a 1/16 allen wrench inserted in the top of the selector switch, turn clockwise to shorten pull length and counter-clockwise to increase it. The set screw can be adjusted so the trigger has enough play to hit the selector switch or not move at all. When shortening the trigger pull, constantly test with every adjustment that the pull is still registered. To make sure you have a reliable pull, push the trigger to the right side and pull while pushing to the right. Do the same pushing the trigger to the left side.(this adjustment is only for electric mode)
The last adjustment is the firing point(where in the stroke the trigger is recognized by the H.E.S.) The H.E.S.(Hall Effect Sensor) looks for a magnetic field(the magnet in back of the trigger). In order for the H.E.S. to know when the trigger is being pulled and not being pulled, the trigger magnet must be close enough for the H.E.S. to sense it when the trigger is pulled but also far enough for the H.E.S. to not sense it when the trigger is not being pulled. For a reliable pull, you want the magnet to be sensed anywhere from the middle to just before the end of the stroke. Insert the same 1/16 allen wrench in front of the trigger. Clockwise moves the magnet closer to the H.E.S.. Counter-clockwise moves the magnet further away. Remember to do the push to the side and pull test. (this adjustment effects both electric mode and hybrid mode.)
If the trigger pull is not registering properly or the board will not boot up properly
If the trigger magnet is too close to the H.E.S. when the trigger is NOT being pulled, the L.E.D. will either not show anything when you turn off and on the battery, or there will be a bunch of characters that dont make sense.
solution - back the magnet out until the board boots up normally
If the trigger magnet is too far from the H.E.S. when the trigger IS being pulled, you will either not register a trigger pull, or it will only register a pull while pulling the trigger straight back or only to one side. Remember, a reliable pull needs to be registered while pushing the trigger from both sides.
solution - If no pull is being registered or a pull is only registered when pulling the trigger straight back and/or from one side only there may be different ways to solve this. Either the magnet is too far back, the trigger pull has been adjusted to be too short, or a combination of the both. If you want to keep that pull length, try moving the magnet closer to the H.E.S. Remember the board may not boot up properly if the magnet is too close. Also remember to keep the firing point between the middle to just before the end of the stroke. You may have to give a little more play in the pull length to get a reliable pull.
