If it hasn't been long since you bought the product, there may be a smell caused by the chemical agents (insulation) in the new motor or the heat of the motor during operation, but the smell will gradually disappear after 1-3 months of use, so please use it with an easy mind.
A chemical agent (enamel) is applied to prevent the motor from becoming electrified, so there may be such a smell initially.
When you use the product over a period of time (1-3 months), it will completely dry out and the smell will disappear naturally, so you do not need to worry about it.
This guide was created for all models, so the images or content may be different from your product.
