Frequently Asked Questions - Concept 30S GRAEF

How to adjust the slice thickness?

Turn the slice thickness adjustment knob (mark 11) to adjust the distance between the blade and the stop plate. The adjustment range goes from zero to approximately 15 mm. For zero thickness (protection), turn the knob below zero.

How to clean the blade safely?

Turn off the machine and unplug it. Wear protective gloves (with pulse protection). Tilt the carriage and close the stop plate. Clean the blade from the center outward with a damp cloth, never from the edge toward the center. Use a clean, dry cloth to finish.

Can I slice frozen foods?

No, the machine is designed only for non-frozen food products such as sausage, ham, cheese or fish. Frozen foods may damage the blade and the machine.

What to do if the blade no longer cuts correctly?

Check if the blade is dull. If so, use the sharpening device provided to sharpen the blade (see chapter 8). If the blade is worn beyond 5 mm, it must be replaced by a professional.

How to sharpen the blade?

Place the sharpening device on the carriage in position '0', set the cutting thickness to 15 mm, then turn on the machine. Turn the knob to '1' to sharpen until a burr forms. Then switch to position '2' for deburring. Clean after use.

Why does the carriage not tilt?

The safety prevents tilting if the stop plate is not completely closed (position below zero). Turn the slice thickness adjustment knob clockwise to the stop, then lower the carriage.

What maintenance products to use?

Use Graef-approved maintenance products such as P3-steril or P3-alcodes, and an H1 maintenance oil (e.g., Graef oil). Never use abrasive products, high-pressure cleaners, or dishwashers.

Can I wash the parts in the dishwasher?

No. Removable parts (blade cover, scraper, spike plate, etc.) must be cleaned by hand with a brush and cloth. The dishwasher may damage them and void the warranty.

What to do in case of power failure?

The machine is equipped with restart protection. After a power cut, it will not restart automatically. Press the start button (green) to restart the machine.

How to transport the machine?

Before transport, close the stop plate by turning the thickness setting to the stop (below zero). Push the carriage fully forward and secure it with adhesive tape. The machine weighs more than 20 kg: move it with two people or use a cart.
