GENERAL MAINTENANCE AND LUBRICATION
Regularly check the tightness of all fixings. However do NOT be tempted to over tighten as some parts are made from aluminum and stripped threads may result. Stripped threads are not covered by the manufacturer�s warranty
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 o1l: 'Napier Gun Oil', alternatively '3 in 1' oil.
Pull-through pad: 'Napier Rifle Clean', alternatively soft cotton cloth.
Pull-through line: 20lb fishing line
As a rule cleaners and oils intended for shotguns and small/fullbore weapons are not suitable.
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.
Feed un-knotted end down barrel from the muzzle end until folded end protrudes about 50mm.
Cut a 100mm length of 'rifle clean' or 100x50mm piece of cloth and pass it between the protruding loop spray the pad with 'gun cleaner' or white spirit, turn the rifle upside down and pull the line back through the barrel slowly.
Repeat steps 2&3 until the pad is clean.
Repeat steps 2&3 once more without any cleaner on the pad to dry the barrel.
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 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.
Note! Only use clean, filtered and dry compressed air, preferably from a diving shop.
Over pressurisation will damage the cylinder beyond repair.
1����� Remove end cap by turning anticlockwise.
2����� If the cylinder is empty, cock the mechanism as described before.
3����� Check that the bleed valve is closed. Turn clockwise to close.
4����� Pull the release ring back on the female connector and push it onto the male connector fitted to the rifle.
5����� Slowly open the main valve (anticlockwise) and observe the pressure gauge.
When the correct filling pressure is observed, (see below) close the main valve (clockwise). Be very careful not allow the pressure in both cylinders to equalise if the decanting cylinder has more pressure that the rifle cylinder.
Note!, at least 50 bar (725psi) is required in the cylinder before the firing valve fully seals. Air may escape from the barrel until this pressure is reached
6����� Open bleed valve (anticlockwise) to release the air from the connecting hose.
7����� Pull back the release ring on the female connector and remove from male connector.
8����� Replace end cap, do not over-tighten
The S400 has a pressure indicator mounted under the stock fore end. This provides a visual check on the amount of remaining air in the cylinder. There are two types of gauge that my be fitted. One has colour graduations the other has numeric. In both cases the graduations indicate 0 to 250 bar.� Do not fill to the required pressure by watching this indicator. The needle reaction speed has been slowed to prevent damage whilst filling and takes time to synchronise to the actual pressure in the cylinder. in the interests of safety the rifle cylinder has a blow-out device that operates at approximately 250bar. Once operated (indicated by deformation of the cylinder end) the cylinder is beyond further use and must be replaced.
4.5mm/.177 cal������� 190 bar
5.5mm/.22 cal��������� 190 bar
Filling to higher pressures will not increase power and may prevent operation completely or cause cylinder damage.
Filling to lower pressures will not reduce power only the number of shots.
