The Chef is one of the most powerful domestic mixers on the market and has a train of five gears to give you the different speeds and power outlets. You get the full power of the Chef's motor at all speeds, so even the heaviest mixtures will never slow it down. A powerful motor makes a powerful noise! Standing your mixer on a hollow cupboard will increase the noise level. Lift the mixer off the working surface to hear the true noise level. Check that the rubber feet are all in place and not worn. Standing the mixer on a felt or rubber mat will help to reduce the noise.
