Using this Bosch oven lampholder is easy. First, make sure your oven is turned off and unplugged to avoid any electrical hazards. Then, find the old lampholder in your oven and carefully remove it. Take your new Bosch lampholder and insert it into the 35mm hole in your oven. Connect the power and earth using the 3 x 6.4mm spade terminals. Put the glass cover on and screw in the 25 - watt SES 300°C oven globe. When it comes to maintenance, keep the glass cover clean by wiping it with a soft, damp cloth. Don't use abrasive cleaners as they might scratch the glass. Also, check the connections regularly to make sure they're tight. If you notice any problems with the lighting, turn off the oven immediately and check the connections or the globe. Always follow the safety instructions in your oven's user manual.
