The model number of your Chef can be found on the underside of the unit. Chef or Major models from 1976 onwards (models beginning with A9 or KM) can use the current range of attachments, with the exception of the food processor attachment (Titanium models only). More information on the attachments available can be found by clicking this link.If the Chef is an A701 or A707, the current attachments will not fit your Chef. If your model is the Chef Sense or Chef Sense XL, launched in September 2014, these models have their own Colander and Frozen Dessert Makers, and an adapter is required to use older attachments, which is included in the box. Attachments can be purchased from Kenwood directly on our website, and also from other good retailers.
