Setup and Assembly
- Unpack: Carefully remove all components from the packaging.
- Wash: Before first use, wash all parts (except the main chopper unit with blades) in warm soapy water, rinse thoroughly, and dry. The main chopper unit with blades can be wiped clean with a damp cloth, taking extreme care around the blades.
- Select Grid: Choose the desired cutting grid (dicing, julienning, or slicing) for your preparation.
- Insert Grid: Place the selected grid securely into the designated slot on the collection container. Ensure it sits flush and is stable.
- Attach Lid: Align the main chopper unit (lid) with the collection container and press down firmly until it clicks into place.
- Prepare Food: Wash and peel your vegetables or fruits as needed. Cut larger items into pieces that fit onto the cutting grid.
Operating Instructions
Follow these steps for safe and effective chopping:
- Place Food: Position the vegetable or fruit onto the center of the chosen cutting grid. For optimal results, ensure the food item is stable.
- Use Food Pusher: Place the food pusher (safety holder) over the vegetable/fruit. This protects your hands and ensures even pressure.
- Chop: With a swift and firm motion, press down the main chopper unit lid. The blades will cut the food, and the chopped pieces will fall into the collection container below.
- Repeat: Lift the lid, remove any remaining food, and repeat the process for additional pieces.
- Collection Container: The transparent container allows you to monitor the amount of chopped food. Once full, detach the lid and grid to empty the contents. The container can also be used for temporary storage with its lid.

Maintenance and Cleaning
Proper cleaning ensures the longevity and hygiene of your MASTRAD Vegetable Chopper.
- Disassembly: After each use, carefully disassemble the chopper by detaching the lid from the container and removing the cutting grid.

- Cleaning Comb: Use the provided cleaning comb to safely remove any stubborn food residue from between the blades of the cutting grids. Do not use your fingers to clean the blades.
- Wash: Wash all components with warm soapy water. The collection container, grids, and food pusher are dishwasher safe. The main chopper unit (lid with blades) should be hand-washed with care.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Food not chopping cleanly. | Insufficient pressure; dull blades; food too large/hard. | Apply firm, swift pressure. Ensure food fits the grid. Do not chop excessively hard items. Blades are not user-replaceable. |
| Food stuck in blades. | Food residue accumulation. | Use the cleaning comb to carefully dislodge food. Rinse immediately after use. |
| Lid not closing properly. | Grid not seated correctly; food obstructing closure. | Ensure the cutting grid is fully inserted and flush with the container. Check for any food pieces blocking the mechanism. |
