CLEANING and LUBRICATING CAUTION: Do not use acids, water and chlorinated solvents. WARNING: Oil and grease that obstruct the bore, even partially, are very dangerous when firing and may cause barrel rupture and serious injury to the shooter and bystanders. Never spray or apply oil to cartridges. Use lubricants properly. You are responsible for the proper care and maintenance of your firearm. MAGAZINE • Make sure the magazine is cleaned thoroughly and that the follower slides easily downward if pressed. • If necessary, lightly oil the walls of the magazine box with Beretta oil or another good grade gun oil. Run a dry, lint-free cotton patch through the box. Do not leave lubricant inside the magazine box. • Due to various bullet lubricants used on some brands of ammunition, the inside of the magazine (especially the inside front radius) should be cleaned every 250 to 500 rounds. BARREL • Spray a 22 caliber bore brush with Beretta oil or another good grade gun oil. Insert the brush into the barrel from the chamber and scrub the chamber and bore thoroughly. If necessary, first clean the bore with a gun solvent. 31
