It is possible that certain conditions may affect a CO2 cylinder, which can impact its proper performance. These conditions include
the usage, maintenance and storage at temperatures that are higher or lower than normal outdoor temperatures (59°F/15°C to
69.8°F/21°C). Another condition may be when the gun is fired rapidly.

1. High temperatures can increase pressure in the CO2 cylinder and also within the gun, leading to higher than standard operating

pressure. This excess pressure could cause the gun to malfunction or be permanently damaged. Maximum storage or operation
temperature should never exceed 122°F (50°C). This temperature can be reached if you leave the gun under direct sunlight on
a bright day. Thus, to ensure proper gun operation, do not expose it to high temperatures or direct sunlight for long periods of
time. Otherwise, the CO2 cylinder could overheat and explode, which may could damage the airgun and cause injuries or death
to people around it.

2. Fast consecutive shooting may produce a decrease of temperature in the gun, as well as the CO2 cylinder. This could result

in lower projectile velocities and may even lower gas pressure enough so that the pistol will not fire. This condition can be
especially apparent when shooting in cold weather and can be avoided by allowing more time between shots. This permits the
gas to increase in temperature and pressure and produce normal velocities.

3. During rapid fire, the muzzle velocity of each shot will diminish. This can affect shooting accuracy and you will get fewer shots

per CO2 cylinder.

4. Care should be exercised to insure that the gun is not shot with a CO2 Cylinder that is low in pressure. Here are some indicators

of insufficient pressure:

A) The sound of the shot is not as loud as when the cylinder is full.
B) The projectile hits the target, but in a lower position than it would with a full CO2 cylinder (That is, the shooting speed

has dropped).
