Inserting and changing the CO2 cartridge

Inserting a CO2 cartridge

Note: Use only 12 g CO2 cartridges! Do not use cartridges containing other gases!
Press the magazine catch down and remove the magazine from the weapon (illustr. 5). Move the magazine shoe (cartridge lock) into the direction "OPEN" and screw the cylinder retaining screw all the way down (illustr. 6). Insert the gas cylinder with its narrow end ahead (illustr. 7), lock the gas cylinder by turning the cylinder retaining screw up and close the magazine shoe into the direction "POWER" (illustr. 8). The C02 cylinder is now pierced and sealed. Insert the magazine until it locks, with the safety of the weapon engaged (illustr. 9).
To make sure the cartridge has been properly pierced, check to make sure that the pistol is unloaded, disengage the safety and shoot in a safe direction. If the pistol will not fire repeat the cartridge loading procedure as described above.
Remove the CO2 cartridge
Engage the safety of the weapon (hammer decocked, see chapter 4). Hold the weapon with one hand on the top side of the grip. Actuate the magazine holder (fig. 5) to remove the magazine. Turn the magazine lever towards "OPEN" and now turn the cylinder retaining screw (fig. 6) all the way down. Allow remaining C02gas to escape. Now the gas cylinder can be removed.

A. Loading the pistol
- Engage the safety of the pistol (hammer decocked, see chapter 4).
- Open the slide by slightly pressing the unlocking lever down, then let it turn back (illustr. 10). Keep the gun in a horizontal position in order to prevent the cylinder magazine from failing out.
- A safety prevents the trigger from being pulled when the weapon is open.
- Remove the pellet cylinder and load the Diabolo pellets head first (see illustration 11) insuring that each is completely inserted.
- In order to prevent malfunctions it is to be made sure that the pellets are seated flush in the chambers of the rotary magazine, or, even better, that they are seated somewhat countersunk in the chambers.
- Insert the magazine (illustr. 12) and close the breech by gripping the front part and push it back until it locks (illustr. 13). The slide release lever must be in a horizontal position.

B. Unloading the pistol
- Put the safety on, (Hammer decocked, see Chap. 2).
- Open the slide by pushing the release lever downward (see illustration 10).
- Remove the pellet cylinder and carefully push the pellets out of the cylinder with the cleaning rod.
- Make sure that there is no pellet in the barrel.
- If there is a pellet in the barrel, push it out with the cleaning rod.
- Never shoot with a used pellet. It could damage cylinder and barrel.

Double Action/ Single Action
The pistol will function in either double-action or single-action mode.
To fire in double action, apply steady pressure to the trigger until the pistol fires.
To fire the gun in "Single Action" means that the internal striker has to be manually cocked prior to firing. Grip the rear part of the slide and pull it back, then release it and allow to move back forward. Then pull the trigger.
For rapid-fire shooting we recommend the double- action mode, for more precise aimed shooting we recommend the single-action mode.
If a pellet fails to be shot after execution of the operation steps mentioned before this could be due to a feed jam.
  • Put the safety ON (hammer decocks, see Chap. 2).
  • Open the slide and remove the pellet cylinder.
  • Check that each pellet is properly inserted in the cylinder.
  • Check the barrel with the cleaning rod to insure that no pellet is lodged in the barrel.
  • Close the breech by gripping the front part of the slide and push it back until it locks (illustr. 13).
  • Aim in a safe direction, turn the safety OFF and shoot the pistol to test the CO2 pressure.
  • If no CO2 pressure is evident, change the CO2 cartridge.
