Manual

b. Position II (Rib of gas valve in slanting position)

When cycling or ejection problems are encountered due to heavy

fouling or icing-up, the gas valve is to be turned clockwise as far as the

stop. In this position, a larger gas quantity acts on the gas piston.

The adjustment of the gas valve is effected manually, and, in case of a

hot or heavily fouled weapon, by means of a cartridge or auxiliary aid.

Firing with the gas valve in position II is an exception. As soon as the

weapon works, the gas valve must be turned back to position I,

otherwise the recoil is intensified and the weapon is unnecessarily

stressed.
