SPECIAL FACTORS RELATED TO CO
2
2.9
Sometimes the performance of a CO
2
-powered air gun is adversely
affected by special factors. An example is when the airgun is used,
kept or stored at temperatures well above or below the normal outdoor
temperatures (15-21° C; 59-70° F).
High temperatures can create a pressure in the 88 g CO
2
cylinder and
the airgun itself which considerably exceeds the normal operating
pressure. Such overpressure can prevent the release of a shot and
cause permanent damage. This airgun should not be stored or used at
temperatures above 50° C (122° F).
Do not use the airgun with an 88 g CO
2
cylinder that has already
lost a lot of pressure.
Signs
of insufficient pressure in a cylinder include the following:
A) The chain magazine does not advance (there is no shot).
B) The shot is not as loud as with a full cylinder.
C) The projectiles hit the target lower than they do when the cylinder is
full (i.e., they have a lower velocity).
!
CAUTION:
Shooting with insufficient pressure can cause
a pellet to lodge in the barrel. See the
instructions on feed jams.
