Remove rearsight. remove two front stock screws and the screw in front of trigger guard and remove action from stock. Undo cocking arm lock screw and pivot screw and remove cocking arm.Undo locking screw and barrel pivot screw and remove barrel. Small screw on left of breech block if you want to remove plunger and spring.Tap out trigger pivot pin and remove trigger and trigger spring (more in minute). Tap out sear pin and remove sear. The trigger bit you pull on goes into the bit that endgages on the sear and has a small pin securing it. These often wangle and I remove the pin and solder the two bits of the trigger together (making sure pin hole lines up)> you could try araldite but make sure pin holes line up ang you grease the pin or use paper clip till glue dries. On the left of the cylinder is a small 4ba grub screw. You need to remove this before trying to undo trigger block--The heads are often broken and you may have to try to tap it round with a small punch or grip it with long nose pliers. I had to drill one out and then retapped hole to 3ba. (screws and taps available from chronos etc and come in handy). Unscrew trigger block. There is not as much pressure as on a lot of guns. Keep pressure on until its undone and slowly release. GO TO PART 2
