9 Compressed air cylinder
The LP400 air pistol is equipped with a screw-on/screw-off compressed air cylin-
der which is approved for compressed air up to 200 bar. This cylinder can be
unscrewed, filled or changed at any time. Caution: the compressed air cylinder
and pressure reducer should be assembled and disassembled only by authorized
specialists. Only original Walther compressed air cylinders are to be used.
Filling the compressed air cylinder
Warning: max. permissible pressure 200 bar
Cylinders of 300 bar are commercially available. These have the same connecting
thread as cylinders with a permissible pressure of 200 bar. When using cylinders
of 300 bar, a pressure reduction valve set to 200 bar must be used when filling.
When refilling, use only oil- and water-free compressed air with a maximum
pressure of 200 bar (DIN EN 12021 – breathing air). Never expose filled pressure
cylinders to a temperature above 50° C. Do not make alterations to the com-
pressed air cylinder or its valves. The provisions of the TRG (technical regulations
relating to pressurized gas) for filling compressed air cylinders must be complied
with. Observe applicable national statutory regulations for refilling. Do not refill
cylinders which are leaky or otherwise unsafe. Empty them in a safe manner.
Screw the supplied adapter onto the refill cylinder or compressor and tighten it.
Unscrew the compressed air cylinder from the weapon and then screw it onto
the adapter of the refill cylinder. Slowly open the valve of the refill cylinder and
close it again after about 1 minute. Screw off the filled compressed air cylinder
and firmly screw it onto the weapon by hand until it stops.
Compressed air cylinders must never be used or stored above maximum pres-
sure.
