How to use
Set the Optimus Crux on stable, level ground clear of flammable material. Attach a compatible gas cartridge according to the cartridge manufacturer’s instructions until the connection is secure. Unfold the pot supports and ignite the burner using a lighter or built-in igniter if available, then adjust flame output to the required heat. Position cookware centrally on the supports and monitor while cooking. After use, turn off the gas at the cartridge, allow the stove to cool, fold the supports and stow the stove in its bag or a dry compartment.
Usage recommendations
Use the stove with appropriate cookware sized to the single burner and avoid oversized pots that may reduce stability. Check cartridge and stove connections for leaks before ignition, follow local regulations for fuel use outdoors, and carry spare cartridges if planning extended trips.
