Safety instructions
When the gun is delivered, the cylinder is not screwed in.
Because of legal regulations and safety provisions, we only
deliver empty compressed air cylinders. Please fill the cylinder
before use (see “Filling the cylinder,” p. 25).
Whenever you ship or mail your gun with the cylinder or send
the cylinder separately, by plane, mail, etc., the cylinder must
always be empty, in other words unfilled and unpressurized (see
“Emptying the cylinder,” p. 31).
The maximum permissible filling pressure is 300 bar at 15°C.
The cylinder cannot be filled using a higher pressure or a greater
filling volume! The air must be dry and free from dust and dirt.
Use only oil-free and water-free pressurized air, in other words
diving-quality air (DIN EN 12021)!
Improper use, filling, storage or other handling of a cylinder can
lead to injury, property damage or even death.
Filled cylinders should not be exposed to temperatures above
50°C or below -20°C. During transport (for instance with high
temperatures in a car) and storage, make sure insulation is
provided, e.g. by storing them in a Styrofoam container or a gun
case.
Store cylinders and refill adapters in a safe, dry, oil-free and dust-
free place.
Be sure to protect cylinders from outside forces, such as falls, etc.
Cylinders that are not properly sealed or have been damaged, or
are more than 10 years old, can no longer be used or refilled.
They must be emptied immediately to render them harmless
(see “Emptying the cylinder,” p. 31). They must be replaced im-
mediately and no longer used. The manufacturing date is marked
on the cylinder. Always treat the cylinder with care, and check it
for cracks before every use. If you see cracks or other damage
on your compressed air cylinder, it should be emptied immedia-
tely and returned to us. The surface of the cylinder cannot be
glued or otherwise manipulated. In particular, no engraving or
other abrasive processes should be undertaken, since this can
cause damage to the pressure container and lead to safety risks.
Always keep the connecting threads and vents completely free
from oil and dirt.

An empty cylinder should never be exposed to temperatures
over 70°C or to flame. Excess temperatures can cause damage.
If this occurs, the cylinder must be sent back to us for inspection.
Never try to open a cylinder yourself or to mechanically modify
it in any way. Valves and manometers should only be installed
and removed by the manufacturer. Please note! Only original
DIANA cylinders (max. 300 bar) should be used! Any modi-
fications and/or repairs to cylinders can only be carried out
by the manufacturer, using original replacement parts. If
this is not the case, all liability and warranty claims shall be
rendered null and void.
The cylinder is equipped with a manometer to indicate filling
pressure. Only check the pressure reading when the magazine
has been removed and the gun is unloaded and uncocked. Under
no circumstances should it be checked while you are refilling the
compressed air cylinder (see “Unloading the gun,” p. 30).
Depending on the construction, the manometer operates with
an accuracy of +/- 3%. Temperature changes can also lead to
deviations in the reading.
For safety reasons (shots cannot be discharged without
pressurized air), the cylinder must always be unscrewed and re-
moved when the gun is not being used, when shooting is finished
and/or the gun is being transported. This removes pressure from
the housing and the valves as well as the gaskets and springs.
Always point the gun in a safe direction while removing the
cylinder!
In addition to the above information, the provisions of the
“Technical Rules for Pressurized Gas,” any operational
safety instructions and the legal provisions of the respective
country must be followed when filling the cylinder, inclu-
ding for commercial purposes. The cylinders CANNOT be
used to transport or fill other types of gases.
For compressed gas containers made of steel, we have decided
to limit the useful life to 10 years. In contrast to aluminum con-
tainers for compressed gas, the different material characteristics
of the steel cylinders and the resulting possibility of a repeat
inspection by the manufacturer after 10 years – as long as the
repeat inspection does not reveal any problems – allow their useful
life to be extended by another 10 years. Thus the maximum pos-
sible useful life is a total of 20 years (example: the useful life of
a 16-year-old cylinder would only be extended by another four
years).
The useful life of steel containers made of compressed gas that
are 20 or more years old cannot be extended through a repeat
inspection. After the end of the useful life, the cylinder should
no longer be used and should be safely emptied.
