MAINTENANCE INSTRUCTIONS
Firearm Disassembly
Lift the fore-end latch (Fig. 4) while pushing the fore-end slightly towards the barrel.
Remove the fore-end away from the barrels (Fig. 5).
Hold the receiver with one hand and the barrels with the other hand. Unlock the breech
mechanism by pressing the top lever. Rotate the barrels around the hinge pin by approximately
45° in order to slide the barrels out of the hinge pin (Fig. 6).
Firearm Assembly
Rotate the top lever to the open position until the latch snaps in. In case the firing
mechanism is released, the protruding firing pins are pulled down. Place the barrels inside the
receiver and slip them onto the hinge pin, rotate the barrels to close the firearm, while the latch
releases the top lever whose subsequent motion will lock the barrels (Fig. 7). It is not possible
to place the barrel inside the receiver without having the top lever arrested in the open position.
Fit the fore-end onto the front surface of the receiver and pivot it on the receiver guiding
surfaces, finally pushing it towards the barrels (Fig. 8). If the firing mechanism is released it is
necessary to release the cocking levers at the same time by opening the top lever.
Once the fore-end has been placed inside the receiver, the latch snaps down under the
fore-end hook. Push the latch finally to closed position. To verify the correct assembly, break
the barrels and close them again.
