The manual emphasizes that the appliance should only be operated on flat, dry surfaces and that all cutting parts are extremely sharp and must be handled by their plastic centers. Essential Attachments and Their Uses
The manual details several specialized tools that expand the machine's functionality beyond simple chopping: Chopper Blade (Sabatier Blade):
The standard "S"-shaped blade used for manual-style chopping of vegetables like onions, parsley, and spinach. Reversible Shredding/Slicing Discs:
A dual-purpose metal disc. One side is used for grating (e.g., cheese and carrots), while the other is designed for slicing (e.g., potatoes for soup). Citrus Juicer: Most vintage owners encounter the same three issues
A cone-shaped attachment for extracting juice from citrus fruits. Kneading Tool:
Specifically designed for mixing simple and complex doughs, though users are cautioned against over-tasking the motor with excessively heavy pastry. www.moulinex-me.com Operating Instructions and Maintenance
Before first use, the manual advises washing all removable parts (except the motor unit) in warm, soapy water. www.moulinex-me.com Our History - Moulinex
The manual will show you the recommended speeds for specific tasks:
| Speed Setting | Task (From the Manual) | | :--- | :--- | | 1 (Low) | Emulsifying mayonnaise, mixing cake batters, whipping cream with the whisk accessory. | | 2 (Medium) | Chopping soft herbs, grating cheese (with the disc), mixing cookie dough. | | 3–4 (High) | Kneading bread dough (using the plastic kneader blade). | | Max (Pulse) | Chopping raw meat, crushing ice, grinding nuts into flour. | The manual will show you the recommended speeds
The original Moulinex Masterchef 750 Duotronic instruction manual listed several optional accessories that are now hard to find but worth hunting for:
If your manual shows these, but you don't have them, search for "Moulinex Masterchef 750 accessories" on second-hand sites.
The Duotronic has a rotary dial with four positions:
| Position | Function | |----------|----------| | O | Off | | Pulse | Spring-loaded – motor runs only while you hold it. Use for short bursts (chopping nuts, breaking down ingredients). | | Speed 1 | Low continuous speed. For kneading dough, mixing batters, light chopping. | | Speed 2 | High continuous speed. For pureeing, grinding, heavy chopping, slicing/shredding. |
Pro tip: Always start with Pulse or Speed 1 for control, then move to Speed 2 if needed. Never switch between speeds while the blade is still spinning – wait for a full stop.
Since you can't call Moulinex support in 1994, here is the fix for the most frequent issues reported by owners:
| Problem | Likely Cause | Solution (From Manual) | | :--- | :--- | :--- | | Machine vibrates violently | S-blade not seated correctly OR dough load uneven. | Stop. Remove lid. Reseat blade. For dough, divide into two batches. | | Lid won't lock | Food debris in the handle hinge. | Run the lid under hot water to melt solidified fat/gunk. | | Slices are turning to mush | You are using the Pulse setting instead of continuous speed (2). | Use constant speed for discs. Pulse is for chopping only. | | Burning smell | Motor is clogged with flour dust (common for 1990s units). | Unplug. Vacuum the air intake vents on the bottom of the base. |
