Thank you for choosing the Preethi Trio Mixer Grinder. This appliance is designed for efficient mixing and grinding of various ingredients. Please read this manual carefully before operating the unit to ensure safe and optimal performance. Keep this manual for future reference.
Image 1: Important information regarding mixer grinder operation. It highlights that operating noise levels are typically 80-90 dB, an initial burning smell may occur due to motor varnish, and 750 Watt mixer grinders are recommended for heavy-duty grinding.
Note on Noise and Smell: It is normal to experience some burning smell when operating your mixer grinder for the first time. This is due to the motor varnish heating up. This should not recur in subsequent uses. Mixer grinders operate with a powerful motor, resulting in a typical operating noise level of 80-90 dB. If noise levels seem excessively high or the burning smell persists, please contact customer service.
