1.you will noticed there is a locking plate on the right side of the interior wall.
2. use a plastic pen so you dont damage the locking plate , push down on the front of lock to disengage the trigger and sear axis pins.
3. push out the axis pins from left to right. the change lever do not come out for maintenance.
4. the sear should fall out but the trigger you need to hold the trigger from underneath , move up alittle and till it forward and from the top with the other hand also moves it forward so the sear disconnect clears the change lever . trigger spring should also drop out but the sear main spring do not.
5. reassembling is exactly the reverse , however its a little tricky putting the trigger spring back , what i do is once the trigger is in place , i use a needle nose plier to place the trigger spring in the slot and then put the axis pin in before installing the sear.
6. push the back end of the locking plate down to lock in the pins, should you forget , dont worry , it will prevent you from sliding the carrier in.
