Safety Note

Gas is a dangerous fuel if basic safety precautions are not followed.
The filling of gas tanks should NOT take place in an enclosed space, always refill in the open air. Low pressure gas should be used i.e. Butane or a Butane/Propane mix.

Each tank carries a test certificate stating the test pressure and the butane/propane mix ratio. 70/30.
The filling of the tank is accomplished in the same way that a cigarette lighter is filled, using a Bix gas refill adapter.

IMPORTANT! ONLY 70 % butane 30% propane mix or 100 % butane gas shoud be used.
