If you need to remove the glass or glass gasket it is a good idea to spray any fasteners with a product like WD40 or PB Blaster prior to this step. This will greatly reduce the possibility of stripping or breaking any screws / bolts during removal. When reinstalling the glass, tighten the fasteners in a crisscross pattern. This will help to ensure there is even pressure on the glass. Do not overtighten.
Glass Care: The following usage and safety tips should be observed:
1. Inspect the glass regularly for cracks and breaks. If you detect a crack or break, immediately begin shutting down the unit. Do not operate the unit until the broken glass is replaced.
2. Do not slam the door.
3. Do not clean the glass with materials that may scratch (or otherwise damage) the glass. Scratches on the glass can develop into cracks or breaks during operation.
4. Never attempt to clean the glass while the unit is hot. If deposits are not very heavy, normal glass cleaners are adequate using a soft, non-abrasive cleaning pad. Heavier deposits may be removed with oven cleaners.
5. Never put substances that can ignite explosively in the unit. Even small explosions in confined areas can blow out the glass.
