E-Remove the barrel (24)

F-Chimneys of the barrel must be dismantled regularly and oiled at reassembly not necessarily with each shooting session but at least monthly if one pulls often.
This is to avoid an oxidation of the pitch of the chimneys which would definitely block the chimneys, that nevertheless it will be necessary to change these ones being used with the repeated blows.
The chimneys are only dismantled with the appropriate key, Of this one, do not try other tools that could only deteriorate them.

G- Sometimes it is necessary to disassemble the drum to remove the powder residue. Unscrew and remove the axle of the loading lever (32) Remove the drum from its housing. If necessary, unscrew the axis of the drum for cleaning and oiling.

With the mechanism completely removed, thoroughly clean each piece to be removed from any black powder residue. Oil each piece when reassembling.

It is not necessary or even advised not to touch the barrel shaft which has been fixed and adjusted by the manufacturer, do not disassemble the handlebars, do not touch the axles (4) (6) (30), the pins (14 and 41) and all other small parts (5, 29, 35, 36, 39)
Dismantling finished all the parts are present it is enough to clean everything with the water and soap to remove all the residues of black powder without forgetting of of all oil to the reassembly

Reassembly:
Proceed in reverse order. There is no difficulty if you follow the reverse order except for the hammer spring which is very easy to go up if you observe the following method well.
In order to engage the spring of the hammer under the hammer roller, the hammer spring screw (20) must be unscrewed in part before the under-guard (21) is put in place, the 2 rear sub-guard screws And the hammer spring underneath the roller and firmly tighten the hammer spring screw (20) which has the effect of bending the spring. This is an exemplary simplicity, although it could be difficult if the hammer spring were screwed completely before putting the guard back in place.
When replacing the barrel, do not forget to put the hammer in the half-cocked position, to lower the cam to stop the complete insertion of the barrel on its axis.
As can be seen from the photographs with the years, the deposit of the residues of powder to well marked the brass at the level of the in custody, proof if it is necessary that the weapon must be cleaned regularly, which the former owner of The weapon had undoubtedly neglected.
PS; I could have used a new weapon to make more beautiful pictures of this demonstration but the pedagogical part would not have been conclusive because some people could have believed that it was useless to disassemble all this for the maintenance, believing that The black powder only dirty the barrel and the barrel, proof here that the powder fouls everywhere.
