30 | Helios Gene Gun System
a. For right handed users (see Figure 16):
Engage the safety interlock switch by pushing in with the thumb. Push the firing trigger with the index
finger to discharge the cartridge.
b. For left handed users:
Engage the safety interlock switch by pushing it in with the lower part of the index finger.
Push the firing trigger with the index finger to discharge the cartridge.
5. Removing the cartridge holder from the Helios Gene Gun is accomplished as follows:
a. Move the cylinder lock on the gene gun forward and to the right so it is latched and the barrel pin
does not protrude behind the barrel (Figure 12).
b. Unlatch the push bar by pulling it outward.
c. Pull back and hold the cylinder advance lever to retract the inner barrel sleeve into the gun barrel
(Figure 13).
d. Pull the cartridge holder up and out of the gene gun. The gun will turn-off after 3 min.
Notes: (1) The firing trigger is functional only while the safety interlock switch is pushed in. The safety
interlock switch activates the trigger button for 30 sec; if the gene gun is not fired within the 30 sec period,
the safety interlock switch must be released, then pressed again to reactivate it. (2) After firing the gun,
there is a 5 sec delay before the gun may be fired again. (3) Advance the cartridge holder by squeezing the
cylinder advance lever between each shot.
Loading Cartridges into the Helios Gene Gun
Each cartridge holder has slots for 12 cartridges. Each slot is numbered along the edge of the cartridge
holder, as seen when loading. The numbers correspond to the firing order when the cartridge holder is
properly positioned in the gene gun. The cartridge holder should be loaded with cartridges beginning with
position 1, then clockwise through position 12 (see Figure 17). Note, however, that the cartridge that is in
firing position is at the bottom of the cartridge holder when it is inserted in the gene gun. Therefore, the
cartridge in firing position will not be visible to the user but will be indicated by the number at the top of
cartridge holder and visible along the cartridge rim.
