06 | OPERATING INSTRUCTIONS ASSEMBLY Make sure there are no shells in the chamber. 1. Remove all dirt and excess oil from gun, especially from the breech area, also barrel interior and ends. 2. Remove the forearm by pushing the forehand iron catch upwards, this allows the nose of the forearm to release. With your other hand and at the same time you are pushing the iron catch release upwards, separate the forearm from the barrel (Photo 1). 3. Lightly oil the already cleaned contact points.
07 | OPERATING INSTRUCTIONS LOADING AND OPERATING YOUR SHOTGUN 1. Slide the safety, located on the tang of the receiver, toward the butt of the gun into the “safe” position (Photo 4). 2. Break the action open. 3. Check the barrels for any obstruction, including dirt and excess oil. CAUTION: Obstructions can increase barrel pressure sufficiently so that the barrel can explode when the gun is fired. This may result in serious injury or death to the shooter and others in the vicinity. 4.
08 | OPERATING INSTRUCTIONS DISASSEMBLY USAGE OF CHOKE TUBES 1. Make sure the gun is unloaded and no shells are in the chamber. 2. Close the action. Place the gun butt on your thigh and remove the forearm by pulling the forearm release latch or pressing the forearm release button. While pulling the nose of the forearm away from the barrels, slide the forearm forward until separated from the barrels. The choke is what controls the openness or tightness of the pattern of your shotgun.
09 | MAINTENANCE MAINTENANCE AND CLEANING 1. Make sure the broad, polished finely fitted mating surface of the breech block and receiver is especially clean and lightly oiled with high quality gun oil. Do not use silicone or lanolin (Do not use WD-40). 2. Run an oil patch through the bore with a cleaning rod starting from the breech end. To prevent leading, use a cleaning solvent and brass brush to clean the bore periodically. Follow this cleaning with one or two clean oil patches.
10 | MAINTENANCE STORAGE AND TRANSPORTATION When storing the firearm and ammunition, store in separate locations, store ammo in a cool, dry location. When storing the gun for a prolonged period of time, It is necessary to oil it heavily with an acid-free lubricant. The external parts must be coated with an anti-rust oil or grease to prevent moisture causing the parts to rust and malfunction. Before usage, the shotgun must be cleaned and wiped dry again as discussed previously.
