The words from belt apply to cartridge box as well as belt. In loading from the magazine care should be taken to push the bolt fully forward and turn the handle down before drawing the bolt back, as otherwise the extractor will not catch the cartridge in the chamber, and jamming will occur with the cartridge following. To fire from the magazine, the command MAGAZINE FIRE may be given at any time. The cut-off is turned up and an increased rate of fire is executed. After the magazine is exhausted the cut-off is turned down and the firing continued, loading from the belt. Magazine fire is employed only when, in the opinion of the platoon leader or company commander, the maximum rate of fire becomes necessary. UNLOAD. All take the position of load, turn the cut-off up, if not already there, turn the safety lock to the left, and alternately open and close the chamber until all the cartridges are ejected. After the last cartridge is ejected the chamber is closed and the trigger pulled. The cartridges are then picked up, cleaned, and returned to the box or belt, and the piece brought to the order. CLIP FIRE. Turn the cut-off up: fire at will (reloading from the magazine) until the cartridges in the piece are exhausted; turn the cut-off down; fill magazine; reload and take the position of suspend firing. CEASE FIRING. Firing stops; pieces not already there are brought to the position of load, the cut-off turned down if firing from magazine, the cartridge is drawn or the empty shell is ejected, the trigger is pulled, sights are laid down, and the piece is brought to the order. Cease firing is used for long pauses to prepare for changes of position or to steady the men.
