REQUIREMENTS ON THE INSTALLATION LOCATION

For safe and faultless operation of the unit, the following requirements of the installation location have to be met:

The unit has to be placed on a solid, flat, horizontal, and non-slipping surface with a sufficient weight-carrying capacity.
Make sure that the unit cannot topple over.
Choose the location in such a way that children cannot reach the connecting cable of the unit.
Do not place the unit on hot surfaces, such as hot plates, or near them.
Never use the unit outdoors, and store it in a dry location.
The unit is not designed for installation in a wall or a built-in cupboard.
Do not set up the unit in a hot, wet, or moist environment.
The socket has to be easily accessible so that the connecting cable can be removed easily in case of an emergency.

ELECTRICAL CONNECTION
For safe and fault-free operation of the unit, the following requirements have to be met during the electrical connection:

Before connecting the unit, compare the connecting data (voltage and frequency) on the type plate with those of your energy network.
These details must correspond so that no damage occurs to the unit. In case of uncertainty, contact a qualified electrician.
The socket has to be protected at least by a 10-amp circuit breaker.
Make sure that the connecting cable is not damaged and not laid across hot surfaces or sharp edges.
The connecting cable must not be stretched tightly.
The electric safety of the unit is ensured only when it is connected to a socket with a protective conductor installed correctly.
Operation on a socket without a protective conductor is forbidden. If in doubt, let the house installation be checked by a skilled electrician.
The manufacturer does not assume responsibility for damage that has been caused by mia missing or interrupted protective conductor.

COMMISSIONING

IMPORTANT!

The grinding angle is 15°.
If the knife is not very blunt, in most cases it is sufficient to resharpen it just a little in stage 2.
Make sure that the knife is in contact with the diamond discs. All you need to do is apply slight downward pressure while pulling the knife slowly towards you.
Additional pressure is not necessary and does not accelerate the sharpening process.
Never pull the knife through the slot from front to back, always from the crop to the tip.
Prevent cuts to the plastic housing. Accidental cuts into the housing will not impair the oper-ation of the unit or damage the cutting edge.
In individual cases, slight scratches on the knife cannot be avoided.
With a 20 cm long knife, each pulling through should take about 4 seconds. Pull shorter knives through in 2 – 3 seconds and longer ones in 6seconds.

Always alternate between the right and left slot in stage 1. This stage quickly ensures a sharp cutting edge, which is then polished at the second stage. Pull the knife alternately through the right and left slots.

Clean the knife to be sharpened before use.
Position the unit in such a way that the numbers for sharpening stages 1 and 2 are facing you.
Insert the plug into the socket and switch the unit on.

SHARPENING

For regular resharpening, it is sufficient to pull the knife through both slots of stage 1 once.
If it is not yet sharp enough, pull it through both slots once more.
If the knife is very blunt, pull it through both slots of stage 1, approximately. 3 – 5 times.
If it is still not sharp enough, pull it through for another 3 – 5 times.
Before proceeding with stage 2, check if a burr has been created along the cutting edge.

IMPORTANT!

You can feel the burr by moving your fingers from the back of the knife over the side surface of the knife towards the cutting edge and then carefully stroking over the cutting surface. You can do this on both sides of the knife; a burr should have formed on one side.
If your last sharpening passage took place in the right-hand slot, there should be a small burr on the right-hand side of the knife edge. If the last pull was in the left slot, you should be able to feel a burr on the left side.
If there is no burr, repeat the process one more time, otherwise continue with polishing in stage 2.

POLISHING

Pull the knife alternately through the left and right slots of stage 2 at an even speed.
To achieve a razor-sharp cutting edge, it is sufficient to pull the knife slowly through both slots of stage 2 once or twice.
If a burr remains, you can further refine the knife by additionally pulling it through during the polishing phase.

IMPORTANT!
A suitable test to assess the sharpness of the knife is to cut a tomato or paper.

CAUTION
Sharpening makes the knife very sharp. There is a danger of injury.

IMPORTANT!
The knife edge can be resharpened approximately 10 times before it needs to be sharpened in stage 1. To resharpen, pass the knife 2-3 times alternately through the left and right slots of stage 2 while maintaining the recommended downward pressure. Ensure that the grinding discs are rotating during the process. Test the sharpness of the knife. Repeat the process as required. As a rule, it is sufficient to resharpen the knife several times in stage 2 before using stage 1.

SHARPENING AND POLISHING KNIVES WITH A SINGLE-SIDED CUTTING EDGE.

IMPORTANT!
Knives with a single-sided cutting edge are only bevelled on one side, either right or left.

To check whether a knife is right-handed or left-handed, hold it as if you want to cut with it.
If the wide bevelled side of the knife is on the right, it is a knife for right-handers.
If the wide side is on the left, it is a knife for left-handers.
Right-handers start in the left slot of stage 2.
Left-handers start in the right slot of stage 2.
In the process, proceed as described on the previous page under “Sharpening” and “Polishing”.
However, only use the right or left slot.

RESHARPENING KNIVES WITH A SINGLE-SIDED CUTTING EDGE

In the process, proceed as described under “Resharpening the knife edge.”
However, only use the right or left slot.

CONVERTING 20° KNIVES INTO 15° KNIVES

IMPORTANT!
The advantage of the Asian knife is based on the thinner cross-section in the area of the cutting edges and the flatter inclination angle of each bevel. If the 20° knife is thick and already has a considerable thickness at the top of the cutting edge, many of the advantageous properties of a 15° knife cannot be realized. Therefore, select thin 20° knives for reworking the cutting edge.

If you want to convert a knife with a 20° knife into a sharper 15° knife, follow the instructions as described in the chapter “Sharpening”. The first grinding process at stage 1 will probably require a few more pulls, but the subsequent polishing will be normal. This method changes the angle of the knife from 20° to 15° and makes it sharper. To resharpen the new 15° knife, see “Resharpening the knife edge”.

SHARPENING SERRATED KNIVES

Serrated knives can only be sharpened in stage 2.

Pull the knife alternately through the right and left slots of stage 2. As a rule, it is sufficient to pull the knife through stage 2 approx. 5 – 10 times.
Test the sharpness of the knife.
If the knife is very blunt, first carry out two quick but complete pull pairs in stage 1 – once in the right and once in the left slot.

IMPORTANT!
Attention: Only carry out a few pulls in stage 1, otherwise you will remove too much metal from the teeth of the serrated knife.

Then pull the knife alternately through the right and left slots, approximately. 5 times in stage 2.

IMPORTANT!
Due to its saw-like structure, a serrated knife will never be as sharp as a knife with a smooth knife.

CLEANING

The outside surface of the knife sharpener can be cleaned with a damp, soft cloth.
This knife sharpener does not require any oils or other lubricants.

REMOVING METAL DUST

The metal dust that has accumulated in the unit during sharpening should be removed about once a year. Remove the small rectangular cover from the cleaning opening on the underside of the unit. There are metal abrasion particles that are held in place by a magnet on the inside of this cover. You can simply wipe off this accumulation of metal particles with paper from the kitchen roll or brush it off with a toothbrush; then replace the cover in the opening. If large quantities of metal dust have accumulated in the unit in addition to the particles adhering to the magnet, you can shake them out through the base opening with the cover removed. After cleaning, reinsert the cover with the magnet firmly and securely into the housing.

Your legal warranty claim in conformity with Section 437 et seq. of the German Civil Code (BGB) shall remain unaffected by this regulation.
