You should clean vour A-500G whenever ii j becomes excessively dirty — and perform a thorough cleaning at least once a year. The barrel should be cleaned, and the action wiped clean and oiled after every day of shooting. The gas system should require only occasional cleaning. If a malfunction occurs, perform a thorough cleaning, to see if it solves the problem, before seeking the services of a Browning Recommended Service Center, the Browning Service l-acility in Arnold. Missouri, or a competent gunsmith.
Normal maintenance can be accomplished with the barrel still attached to the receiver (oiling and wiping down). More careful cleaning requires removal of only the barrel from the receiver (cleaning the barrel), and the removal of several gas system
components. A complete cleaning requires removal of the breechblock and trigger group.
PERIODIC OILING —
Ordinary good judgment will indicate that the metal parts of the gun should receive a light film of oil after the gun has been exposed to weather or handling. Occasionally, a small drop of oil may be placed on the end of the action bar where it slides along the track in the receiver (See Figure 22). This will help to relieve friction and ensure smooth operation.
Also, lightly lubricate the breechblock, rotary bolt and spring guides. If the gun has been exposed to much dust, dirt, mud or water, the principal working parts including the gas system, should be wiped clean and lubricated with a light film of oil. Browning Oil is recommended.
DO NOT POUR LA RGE QUANTITIES OF OIL INTO THE ACTION. A LARGE EXCESS OFOIL WILL RUN BACK INTO THE WOOD OFTHE STOCK AND CAUSE SOFTENING OFTHEWOOD, WITH CONSEQUENTIAL LOOSENING OFTHE STOCK.
CLEANING THE BARREL —
The correct procedure for cleaning your A-500 shotgun is as follows:
1. BE CERTAIN YOUR SHOTGUNS MAGAZINE, FEEDMECHANISMAND CHAMBER ARE UNLOADED. PLACE THE "SAFETY"IN THE "ON SAFE" POSITION AND LOCK THE BOLT O THE REAR. ALWAYS WEAR PROTECTIVE SAFETYGLASSES DURING ALL DISAS-SEMBL Y AND CLEANING PROCEDURES.
2. Remove the barrel so that it can be cleaned from the breech end (See "Disassembly * on page 18).
3. Using a shotgun cleaning rod with tip and patch large enough for a snug lit in the bore, insert the rod and patch in the breech end of the barrel and run back and forth through the bore several times. Remove and wipe the In vector tube, lube threads and barrel threads, and lightly oil.
leading by looking through bore toward light. Leading will appear as dull longitudinal streaks and is usually more predominant near the muzzle and just forward of the chamber.
5. A normal amount of leading can be expected with today's high velocity loads and improved wads but this is not serious. If or when leading should become heavy, it can be removed with a brass bore brush. Make sure a choke tube is installed. Spray the bore or the bore brush with a good powder solvent, and scrub the bore until leading is removed. To prevent brass bristles from breaking off. the brush should be pushed completely through the bore before being withdrawn.
6. After leading has been removed, the bore should be wiped dry with a clean patch, and then a lightly oiled patch run through it for preservation.
CLEANING THE GAS SYSTEM —
I. Kemove the gas piston, sleeve bar assembly and return spring from the magazine tube. Spray the tube with Browning oil Cor a good quality powder solvent) and wipe clean. Kemove the return spring from the sleeve and wipe clean. Spray the inside of the sleeve and wipe off of any buildup.
2. To clean the gas system, first spray the gas piston with a good powder solvent and brush it thoroughly to remove any deposits (an old toothbrush is ideal for this). Spray into the gap between the inner and outer portions of the piston.
3. Clean the gas regulation valve system (it is located inside the barrel ring guide/gas cylinder) by spraying it with a aerosol Browning Oil or a good powder solvent, and brushing any deposits free (See Fig-lire 23). NEVER use a steel brush on any of the gas coponents.
Pay special attention to the gas pressure vents (two large holes on opposite sides of the barrel ring guide/gas cylinder), and the two gas pons (seen inside the gas cylinder at the top, when viewed from the breech end). Spray again to wash away the loosened deposits and wipe clean. A NONFLAMMABLE sol vent bath can be used to immerse the parts, but i( is not necessary.
