To load the drum magazine, one must:
1.Remove the cover:
a) holding the magazine in the left hand, press the magazine latch knob upward
from the bottom with the middle finger, and with the thumb of the right hand
rotate the cover latch approximately 90 degrees;
b) holding the magazine in the left hand, as shown in figure 56 , remove the
cover with the right hand.
2.Tighten the magazine spring (Figure 57): take the magazine in the left hand,
and with the fingers of the right hand, grasp the dogs of the drum and tighten
the spring by rotating the drum counter-clockwise. You should hear eight audible
clicks during this process.
When tightening the spring:
a) do not release the drum until you have heard the clicks;
b) ensure that during the drum's first rotation, the follower slides through the
internal course of the volute chambers, and the chambers themselves remain
immobile (if this caution is not observed, the cartridges from the inner chamber
will not be delivered).
3.Load cartridges into the magazine. Take the magazine in the left hand, tilt
it slightly, and load 71 cartridges along the entire length of the inner and outer
courses of the chambers.
4.Release the drum. Taking the magazine in the left hand, with the right hand
slightly rotate the drum counter-clockwise. Pressing with the middle finger of the
left hand on the magazine latch knob, release the drum, putting the cartridges under
pressure of the spring.
If any cartridges have dislodged upward, push them back down level.
5.Install the magazine cover. Press the magazine latch knob upward to stop
and secure the cover with the latch.
Notes:
1. Magazines are fitted to submachine guns. Therefore, one must check the serial number
on the cover and body of the magazine with the serial number on the submachine gun.
2.If, after tightening the spring, the need arises to release it, hold the drum in the
right hand and release the spring gradually, one-fourth of a turn at a time.
If the spring is released all at once, the limiter gate of the volute chamber
[this is a gate near the mouth of the magazine that allows the follower to pass from the
inner course to the outer course] might be struck and broken or bent.
To load the column magazine, one must:
1.Grasp the magazine in the left hand with the mouth upward and the lug to
the left, with several cartridges in the right hand.
2.Holding the next cartridge by the thumb and index finger of the right hand
on the projectile and shoulder of the case, press down on the follower with
the cartridge rim and insert the cartridge under magazine lips with pressure
of the thumb on the case shoulder.
3.Pick up the next cartridge in the same manner, and placing its rim on the
cartridge just inserted into the magazine, insert this cartridge under the
magazine lips.
4.Load 30-35 cartridges into the magazine in the same fashion.
A special tool (Figure 58) can be used to load cartridges into the column
magazine. This tool is fastened to the mouth of the magazine, with its opening
toward the front.
When loading a magazine with this tool, position a cartridge in front of the
plunger, and push the cartridge in the magazine downward by pressing on the
plunger. The free cartridge can then be slid position under the magazine lips.
