need to unscrew the compressed air cylinder when you have finished shooting. If
you do not expect to use the weapon for a period of more than two to three
weeks, you should remove the compressed air cylinder so that the system is no
longer under pressure. This prolongs the life of the seals. We accept no respon-
sibility for any damages arising from alteration of parts, use of parts other than
original Walther parts or failure to follow the operating instructions.
Service life of compressed air cylinders made of aluminum:
Past experience and further testing using the latest technology available indicate
that the manufacturer-specific service life of aluminum compressed air cylinders
should be limited to 10 years. This ensures a maximum degree of safety for users
and third parties.
Out of concern for users and third parties, we cannot recommend prolonging
the service life of aluminum cylinders through “reconditioning” or “inspection”
that involves pressure tests but does not include investigation of their internal
structure (especially microstructure). In view of the many years of stress on the
material (including especially possible damage, alteration and improper use),
such tests cannot give a 100% guarantee that aluminum cylinders are safe to
use for an extended period.
For this reason, compressed air cylinders made of aluminum must not be used if
they are more than 10 years old (according to the manufacturing date shown on
the cylinders). Empty them in a safe manner.
Additional important information on the use of compressed air cylinders
• If you transport a compressed air cylinder by airplane or send it by mail, it must
be empty.
• Check the pressure level indicator of a compressed air cylinder only when your
air gun is unloaded and decocked. The pressure level indicator has an accuracy
of ±10%. Temperature variations can also affect the level shown.
