Fill the torch with any standard butane refill canister before using. Ensure the flame is out before refilling. Insert the refill tip into the filter valve. A pumping action works best and filling will take about 10 seconds. To light:
Turn the control valve counter-clockwise per instructions on the pen until a small amount of fuel can be heard escaping. Ignite the fuel and adjust the control valve to the desired intensity.
To clean the blow torch slip off the burner and release a few shots of butane directly in the orifice to clear it of unwanted particles.
