1. Allow unit to cool and put protective cap
on for storage.
2. If your unit is not going to be used for
awhile, store in the following manner.
Store in proper location avoiding elevated
temperatures and away from children.
3. Leave tank approximately 1/2 full so
lubrication of fuel pickup filter stays wet.
4. Set flow control valve at setting X.
How to Empty Tank of Butane Gas if Needed
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 fingers
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 carefully
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.
