Resumen del manual
If a cartridge does not fully chamber, do not ‘pound’ on the slide handle to force the bolt closed. Rather, retract the slide, eject the cartridge and determine the cause of the problem. (See “Bore Obstructions Warning” p. 19) 6. To minimize the probability of an unfired cartridge being jammed should it ‘fall back’ onto the magazine, remove the magazine before retracting the slide. When extracting an unfired cartridge, tip the right side of the rifle towards the ground so that gravity will assist the cartridge to fall clear of the magazine well. Always retract the slide briskly whenever extracting a live cartridge. Take care to see that a cartridge is not forcibly ejected against a surface where the primer might be set off. Alterations to the rifle or use of non-Ruger magazines and accessories may cause malfunctions. See “Alteration Warning” on page 8. If the above procedures do not result in a smooth and reliably functioning firearm, don’t use the gun. The rifle can be returned directly to our Newport, New Hampshire Product Service Department for repair. See the Service and Parts Policy section, page 34, of this manual for packing and shipping information. WARNING –MALFUNCTIONS A cartridge can be “discharged” before it is chambered if its primer receives a sharp blow. If a cartridge hangs up, jams, or binds when being chambered or when being fed from the magazine into the chamber, do not attempt to force it into the chamber by pushing or striking the bolt. Any jam or feeding problem is a signal to immediately stop using the gun until it can be determined what is wrong. Most failures of a cartridge to feed or to chamber are caused by a damaged magazine, improper gun handling, or defective ammunition. Whatever the cause, cartridge jams can result in the potentially dangerous situation of a cartridge discharging before it is chambered. If this occurs, the cartridge case will rupture and its fragments will fly out of the gun with sufficient force to cause injury. Always wear shooting glasses and hearing protectors! Keep face away from chamber! STRIKING RIM OR PRIMER CAN BURST CARTRIDGE 22 WARNING –DISASSEMBLY 13a2Safety.. "ON" 3b4 Always unload a firearm before cleaning, lubrication, disassembly or assembly. UNLOAD BEFORE CLEANING DISASSEMBLY Be Sure Rifle Is Unloaded! Although The Mini Thirty Rifle can be disassembled, reassembled, and cleaned in almost any surrounding, it is preferrable to carry out these procedures on a workbench or table which has a covered top. A piece of shallow nap rug or an old blanket is an ideal covering. Such a covering keeps the rifle from slipping and being scratched. 1. With the rifle pointing in a safe direction, safety “ON”, remove the magazine by pushing catch forward to release magazine, while drawing magazine down and forward (See Fig. 7). Figure 7 Figure 8 2. Pull the slide handle all the way to the rear and release. Make sure safety is “ON” (See Fig. 8). NOTE: Hammer must be cocked and safety must be “ON” to accomplish disassembly and reassembly. Again, be sure chamber is empty! 23 3. Use a 1/4” diameter steel rod, punch, screwdriver shank, or other suitable instrument inserted into the hole in the rear of the trigger guard as a lever to spring open the trigger guard from its latched position (See Fig. 9). Figure 9 WARNING: Do not use a cartridge to unlatch the trigger guard because of the danger of loosening the bullet in the cartridge case (See Warnings in “Ammunition” section, p. 11). Figure 10 4. Fold rear sight down. Invert rifle and remove trigger housing assembly by carefully pulling it upward (See Fig. 10). Be careful not to damage stock when removing or replacing the trigger housing assembly. 5. Remove barrel/receiver assembly from stock by swinging rear end away from action slightly, then pull stock out of engagement with gas block (See Fig. 11). Figure 11 Figure 12a Figure 12b 6. Remove buffer guide rod and recoil spring (See Figs. 12a and 12b). CAUTION: The spring is heavily compressed -– use eye protection and care when disassembling and reassembling to prevent the rod and spring from escaping forcibly and possibly causing injury. NOTE: When removing the buffer guide rod, note positioning of the projection on its end with relation to the buffer cross pin. The long tongue portion of the rod (“a”) must go under the cross pin (“b”) in Figure 12a, at the time of reassembly. 24 7. Remove the buffer cross pin and the buffer bushing if there is any concern they will fall out during remainder of disassembly. Note the position of the flat on the buffer bushing. 8. Pull slide handle to the rear. Align locking projections on slide with disassembly notch on receiver. Remove slide (See Fig. 13). 9. Remove bolt lock cover plate by carefully tapping downward (with a soft-metal punch) at point “a”. (See Fig. 14). With cover plate removed, depress bolt lock plunger, “b”, which will allow ejector/bolt stop, “c”, to be lifted out. (See “Caution” in step 6, p. 24) 10. Pull the bo...
