Packing the stove.
Turn off the stove and allow it to cool properly. Disconnect the gas can-
ister. It is normal for a small amount of gas to fizz out when you un-
screw the gas canister. Fold down the head of the burner by pushing
down the metal ring between the fuel control valve and the burner head.
WARNING! Never transport or store the stove with the gas canister
connected.
MAINTENANCE
We recommend that when the stove has not been used for a while, you
check the O-ring where the stove connects to the gas canister. If the O-
ring is not in place, or is worn or damaged, leakage may result. Replace
the O-ring by teasing it out with a tool such as the blunt end of a sewing
needle. Never use a sharp or pointed object that can damage the seal
surfaces. Fit the new O-ring with care to avoid damaging it.
ABOUT THE GAS
Optimus Crux is designed for use with a gas
canister containing a 70/30 mix of butane and
propane with a threaded valve per the EN417
standard (shown on gas canister). As a rough
guide, 300 grams of gas should last one person
one week.
IN COLD WEATHER
The butane/propane mix is adversely affected by the cold. The gas mix
becomes less efficient even at 0 degrees Celsius. The butane ceases to
vaporize and the stove runs solely on propane. If the propane runs out,
you can only use the rest of the container at temperatures above
freezing. One tip is to keep the gas canister warm inside your jacket or
in your sleeping bag at night. You can also place the holder in
lukewarm water. The canister must never be exposed to temperatures
above 50 °C (122 °F). Never shake the canister when
the stove is in use as you risk big flames shooting up.
