Use only a premium grade butane fuel.  Refuel your MPL in a well-ventilated area away from open flame or source of heat/sparks.

Hold the MPL so that the filling valve is facing up. (The filling valve is located in the center of the black knob at the bottom of the MPL). Place the butane fuel can nozzle into filling valve and depress the can several times with a firm, even pressure.  Be sure the butane can nozzle is seated correctly in the filling valve. If butane leaks, try re-seating the nozzle. 

Butane fuel is not only highly flammable, it is very cold when it escapes into the air during filling so be careful.  Wait at least 2 minutes after refueling before using your MPL; this allows the fuel and seals to stabilize and any vapors to dissipate.  Igniting prior to 2 minutes may cause a fire or damage the internal seals and result in a malfunction.
