Troubleshooting Causes And Remedies

If your firearm is properly used and maintained, malfunctions will rarely occur. However, if such a situation does occur please observe the following instructions.

CAUTION - if a malfunction occurs, the possibility of an unintentional discharge is substantially increased. For this reason, when clearing malfunctions, observe the Safety Instructions already mentioned above. Keep the rifle pointed in a safe direction, do not turn the rifle against your body or anyone else's. Do not place your hands in front of the barrel!

Malfunction

Possible Cause

Remedy

A round has not been fed into the chamber.

Magazine is not fully inserted or is damaged. The rifle or cartridges are fouled (dirty).

Insert magazine properly or change magazine. Clean the rifle and cartridges and wipe them dry or as the case may be slightly lubricate.

Firing Pin hole fouled (dirty) or improper lubrication agent used during low temperatures conditions.

Follow the Safety Instructions according to point 19. Disassemble and clean the firing pin or use low temperature lubricant.

A shot sounds "weak".

The primer has been activated but no powder load was inside the cartridge case.

Unload the rifle and check that the bullet is not lodged in the barrel. Any subsequent shot could cause damage to the barrel!

The spent case has not been ejected.

Cartridge chamber, extractor or ammunition dirty or unsuitable lubricant in low temperature environment.

Clean and wipe the rifle dry or eventually lubricate lightly with a suitable agent. Use clean and new ammunition.

If you cannot clear away any malfunction in the manner described above, entrust the rifle to a competent gunsmith for inspection and repair.
