I have an LK 550 where I replaced the insert. Now I can´t get out enough heat from it, can I do something about it?

You can increase the maximum temperature. You can do this as follows:  Turn the knob counterclockwise to (+). Loosen the screw and put the knob to one side. Then turn the knob in the "air" clockwise towards (–). This adjustment can be made incrementally, with a ¼ turn corresponding to approx. 7°C. Replace the knob and feel for when it grips the cog. Fasten the screw and then turn the knob to max (+). Maximum calibration to increase the temperature is a ½ turn
