MAINTENANCE

FIXINGS

REGULARLY CHECK THE TIGHTNESS OF ALL FIXINGS. HOWEVER DO NOT BE TEMPTED TO OVER TIGHTEN AS SOME PARTS ARE MADE FROM ALUMINIUM AND STRIPPED THREADS MAY RESULT. STRIPPED THREADS ARE NOT COVERED BY THE MANUFACTURERS WARRANTY.

BARREL

FOR ULTIMATE ACCURACY, CLEAN AND RE-LUBE THE BARREL FREQUENTLY. IT IS DIFFICULT TO ADVISE HOW OFTEN IS BEST FOR EVERY CIRCUMSTANCE, BUT EVERY 250 SHOTS IS NOT TOO OFTEN IF THE DESIRE IS TO KEEP THE BARREL IN THE BEST POSSIBLE CONDITION.

THE CORRECT MATERIALS ARE VERY IMPORTANT. AIR ARMS ONLY USES PRODUCTS MADE BY NAPIER LISTED BELOW IS THE NAPIER PRODUCT AND A MORE GENERALLY AVAILABLE ALTERNATIVE   IF POSSIBLE USE NAPIER FOR THE BEST RESULTS.

CLEANER:  'NAPIER GUN CLEANER', ALTERNATIVELY WHITE SPIRIT

OIL :  'NAPIER GUN OIL¹, ALTERNATIVELY '3 IN 1' OIL.

PULL-THROUGH PAD :  'NAPIER RIFLE CLEAN', ALTERNATIVELY SOFT COTTON CLOTH. PULL-THROUGH LINE : 201b FISHING LINE

AS A RULE CLEANERS AND OILS INTENDED FOR SHOTGUNS AND SMALL/FULLBORE WEAPONS ARE NOT SUITABLE.

1                CUT A PIECE OF LINE THREE TIMES THE LENGTH OF YOUR BARREL, FOLD IN HALF AND TIE ENDS
TOGETHER. REMOVE SILENCER IF FITTED. OPEN LOADING BOLT

2                FEED UN-KNOTTED END DOWN BARREL FROM THE MUZZLE END UNTIL FOLDED END PROTRUDES

ABOUT 50mm.

3          CUT A 100mm LENGTH OF 'RIFLE CLEAN¹ OR lOOxSOmm PIECE OF CLOTH AND PASS IT BETWEEN THE

PROTRUDING LOOP. SPRAY THE PAD WITH 'GUN CLEANER¹ OR WHITE SPIRIT, TURN THE RIFLE UPSIDE DOWN AND PULL THE LINE BACK THROUGH THE BARREL SLOWLY.

4                REPEAT STEPS 2&3 UNTIL THE PAD IS CLEAN.

5                REPEAT STEPS 2&3 ONCE MORE WITHOUT ANY CLEANER ON THE PAD TO DRY THE BARREL.

6                REPEAT STEPS 2&3 ONCE MORE WITH THE PAD SPRAYED WITH 'GUN OIL' OR 3 IN 1 OIL.

IMPORTANT : THE REASON FOR TURNING THE RIFLE UPSIDE DOWN IS TO PREVENT EXCESS CLEANER/OIL FROM PASSING DOWN THE TRANSFER PORT INTO THE FIRING VALVE CHAMBER.

LUBRICATION

LUBRICATION OF THE INTERNAL MECHANISM IS NOT COVERED IN THIS HANDBOOK. THIS IS BEST PERFORMED BY A COMPETENT GUNSMITH OR THE FACTORY AND IN ANY CASE SHOULD NOT BE

REQUIRED UNTIL THE ANNUAL SERVICE.

 

APPLY A SMALL DAB OF GREASE ON THE LOADING BOLT AND WORK-IN BY MOVING THE BOLT FORWARDS AND BACKWARDS WIPE OFF EXCESSIVE GREASE. PREFERRED GREASE IS 'NAPIER G95 GUN GREASE'

ON RETURN FROM EVERY SHOOTING SESSION, WIPE ALL OVER THE EXTERIOR WITH AN OILY RAG TO PRESERVE THE SURFACE FINISH DURING STORAGE.
