Using your Simpson stove control knob is a breeze. Just find the corresponding control on your stove and firmly push the knob onto the shaft. Make sure the flat side of the shaft aligns with the flat part of the knob hole and that the pointer is facing the right direction. When using the stove, turn the knob gently to adjust the heat settings for your hotplates, grill, or oven. As for maintenance, keep the knob clean by wiping it with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the finish. If you notice any issues like the knob becoming loose or hard to turn, check to see if it's properly seated on the shaft. If problems persist, don't hesitate to contact us. And remember, this knob comes with a full guarantee, so you can use it worry - free.
