OK guys!

I'll have to do something on this, maybe this week-end.
Anyway, it goes like this:
-First, get the upper handguard out by pinching its retaining tabs and pivoting it upwards and out.
-Release the magazine and put it aside.
-Take a live 7,62x39 round and insert its point into the hole in the bayonet's base; push on it while sliding the barrel retainer forward out of its grooves.
-Grasp the barrel near the front sight and pivot it upwards and to the rear to take the barreled action out of the stock.
-Clean the inside of the stock near the piston inletting.
-Now, put the magazine back in and arm the action. It will stay open.
-Grasp the U-shaped channel connecting piece betwen the annular piston and the sprung secondary actuating part, pull it to the rear while disengaging its front edge from the circumferencial groove in the piston and lift it out. This makes cleaning the piston zone easier.
Get the magazine out again and close the action.
-Push on the action cover until it reaches the cutouts in the slide races then CAUTIOUSLY lift it by the rear and let the springs push it out to the rear, over the action's end. Careful: the springs may kink if not controlled.
-Push the safety in, then pull the rear part of the triggerguard to the rear (it takes some effort) and disengage it from its locating nubs; pivot the triggerguard downward and to the front of the action. The entire trigger-hammer block can now be slid out of its lugs. Do NOT take it apart any further! Clean with crudcutting spray then dry lube (also, put a dab of lithium grease on the hooking surfaces and on the contact surface of the hammer).
Put the barrel/action assembly upside down, slowly slide the carrier/bolt assy to the rear and slightly pivot it out when it reaches the slide cutouts.
Now, disassembling the bolt is another chapter; I'll tell you in more detailed terms when I finally shoot the pics.
Don't go away, more to come!
PP.
