Using this Bosch oven lamp cover is easy. First, use the included removal tool with an internal diameter of 63mm to take out the old lamp cover. Then, carefully install the new glass cover in its place. Make sure it's properly seated. When using the oven, avoid hitting the lamp cover with hard objects to prevent breakage. For maintenance, clean the cover regularly with a soft, damp cloth. Don't use abrasive cleaners as they might scratch the glass.
