AIR CYLINDER FILLING
USE ONLY CLEAN, FILTERED AND DRY COMPRESSED AIR!
For filling the compressed AIR CYLINDER use only compressed-air bottle, compressor or mechanical
pump complying with your country’s requirements for use with such devices and limited to 230 bar
operation.
DO NOT ATTEMPT TO EXCEED THE 200 BAR AIR PRESSURE! The AIR CYLINDER can be
damaged irreversibly and thus the gun in whole. For filling the AIR CYLINDER you can find in
package an adapter (Fig.2). In package you can find also three allen keys for adjusting below mentioned
options.
Do NOT USE AIR CYLINDER LONGER THEN 10 YEARS.
Filling the AIR CYLINDER with the air pressure gauge
This type of AIR CYLINDER must be first removed (unscrewed) from the gun.
- Screw the adapter (A) on the valve of the compressed-air bottle.
- Screw the AIR CYLINDER (B) on the adapter (A) attached to the valve of the compressed-air bottle.
- Check that the release screw at the adapter is closed.
- Slowly open the main bottle valve and simultaneously check the value shown by pointer of the
pressure gauge. As soon as it approaches 200 bar (maximum) value, close the valve.
- Check again the value indicated by the pressure gauge.
- Turn the release screw to release the excessive air from the adapter.
- Unscrew cautiously the AIR CYLINDER from the adapter.
- Open the lever to reach the full rear position (Fig.4)
- Screw the AIR CYLINDER in the receiver.
DURING THE MANEUVERING THE REMOVED AIR CYLINDER KEEP IN MIND THAT THE
GUN REMAINS COMPRESSED BY THE AIR IN THE REGULATOR. THE AIR HAS
SUFFICIENT ENERGY FOR THE SHOT. WE RECOMMEND UNLOADING THIS AIR BY DRY
FIRE SHOOTING WITH RIFLE MUZZLE POINTED IN A SAFE DIRECTION.

Note: FILLING TO A HIGHER PRESSURE WILL NOT INCREASE POWER and may actually
hinder operation, filling to lower pressures will not reduce power, only the number of shots. If the rifle
is continually fired when the pressure in the compressed-air AIR CYLINDER is below refill pressure
(less than 60 bar), the remaining air will eventually escape through the barrel spontaneously. This is not
harmful to the rifle but can cause surprise to yourself or bystanders.
Note: The rifle must be unloaded when replacing the AIR CYLINDER.
