1. Only empty fuel tank in a well
ventilated area and away from
ignition sources. Remember
butane is heavier than air.
2. Depress the filler valve at the
back of the tank with a small
bladed screwdriver and let the
butane gas escape through
the small orifice opening. It
takes approximately one
minute for the butane to
escape from the tank.
Be careful that the butane
does not hit against your fin-
gers or hands. This could
cause frostbite of the skin.
3.One method is to poke a small
bladed screwdriver through a
piece of paper and then care-
fully depress the filler valve.
The escaping gas will hit the
paper and not your hand.
4. Never turn gas lever to “ON”
and allow gas to evacuate
through the ejector/tip. Doing
this will clog the ejector and
lead to premature failure.
5. Never try to unscrew
the filler valve as it is
adhesively bonded to the
tank. Breaking of this bond
will destroy the unit, caus-
ing the tank to leak.
