The frequency of greasing your KitchenAid mixer depends on the model and how frequently you use it. KitchenAid stand mixers are designed to be low-maintenance and generally do not require frequent greasing. Here are some general guidelines for greasing your KitchenAid mixer: 1. New Mixers: For new KitchenAid mixers, it's recommended to grease the gears after the first 50 hours of use. This initial greasing helps to ensure smooth operation and longevity. 2. Regular Maintenance: For most home users who use their KitchenAid mixer occasionally or for standard home baking tasks, greasing is typically required every 1 to 2 years or after approximately 100 hours of use. However, if you notice any unusual noises or resistance during operation, it's a good idea to check and grease the gears earlier. 3. Heavy Use: If you use your KitchenAid mixer frequently or for heavy-duty tasks such as kneading bread dough or making large batches of heavy mixtures, you may need to grease the gears more often, approximately every 6 to 12 months or after around 50 hours of use. Keep in mind that the frequency of greasing may also depend on the age and condition of your mixer. Older mixers or those that have been used extensively may require more frequent greasing to maintain optimal performance. It's essential to use the right type of grease, such as food-grade grease or the one recommended by KitchenAid, to ensure that the mixer remains safe for food preparation. If you're unsure about greasing your specific model, refer to the user manual that came with your KitchenAid mixer for the manufacturer's recommendations and instructions. Additionally, periodic visual inspections and regular cleaning of the mixer's exterior and attachments can help keep it in good working condition and extend its lifespan.
