Electrical safety

• Before connecting the appliance to the power supply for the first time, make sure that the voltage on the appliance label corresponds to that of the household electrical outlet.

• The electric appliance is designed to power from 1/N/PE ~ 230 V 50 Hz.

• The electrical safety of the appliance is guaranteed only if it is properly connected to the mains.

• Electrical protection class I equipment is equipped with a protection against electric shock by means of protective earthing of inanimate parts, which can become dangerous when the device is malfunctioning. Always connect such devices to properly installed mains sockets that are equipped with earthing conductors and have a properly grounded earthing conductor.
  All electrical equipment is equipped with a three-wire power supply.

• Class II electrical equipment is protected against electric shock by double insulation or by enhanced insulation of hazardous live electrical parts. Device of protection class II it must not be equipped with means to connect protective earthing.

• Class III electrical equipment is a device that is powered by a small safe voltage source (battery or accumulator) and does not present any danger to the user from electrical shock.

• In order to provide increased safety against the risk of electric shock due to the use of electrical appliances by laypersons, it is recommended to install the power supply circuit for sockets with a rated current not exceeding 20 A RCD with a rated operating current not exceeding 30 mA.
  To ensure the safety and correctness of the electrical installation, consult a qualified electrician.

• Only use a power cord with a plug (mains lead) supplied with the device and compatible with a wall socket. Using another cable may result in fire or electric shock.

• Always connect an electrical appliance to an easily accessible mains socket. In the event of an operating fault, the appliance must be switched off as soon as possible and disconnected from mains supply.

• The power cord and mains plug must always be easily accessible for safe disconnection of the electrical appliance from the power supply.

• Do not pull off the power cord by pulling the cable. Disconnect the power cord by pulling the plug behind the power cord plug.

• If you use an extension cord, make sure that the total rated power of all devices connected to the extension cord does not exceed the max. current load on the extension cable.

Before first use

Do not plug the appliance into the mains during preparation.
Unpack and remove all packaging material from it. To remove any dirt that may have occurred during the packing process, clean it with a dry cloth that does not release the fibers. (See „Cleaning and maintenance“ in this manual).
Do not immerse the machine in the water! Clean the surface with a cloth moistened with water.
Then dry it thoroughly.
Never immerse the engine unit in water or other fluid!
The appliance is intended for home use only!

Preparation and operation

Location

Disconnect the appliance from the power supply before locating it. Then lay it on and press it against a flat, firm surface so that the suction cups cling to the surface and the device firmly in place. For better adhesion, we recommend that the suction cups be slightly moistened before placement.

Grinding

1. Plug in the machine.

2. Switch on the device with the 0/I switch by switching it to position I. Always switch on the device before inserting the knife into the groove!

3. When the wheel speed is running, you can insert the blade into the groove.
   Approach:
   Clean the blade and insert it into the appropriate groove when the grin- ding wheel rotates. Bend the blade with adequate force so as not to reduce engine speed There are two abrasive parts as shown in the picture: Part 1:
   Part 1 is for the first grinding, resp. a rough cut of the blunt knife to create the correct blade shape. Insert the knife completely to the device and min. triple it evenly toward you, alternating the groove for the left and right side grinding.
   When grinding the tip of the knife, gently lift the handle to evenly curve the tip of the tip.
   Part 2:
   Part 2 is designed to fine-cut the knife blade to form a sharp blade. Insert the knife completely with the handle and min. triple it evenly toward you, alternating the groove for the left and right side grinding. One stretch should take 3 or more seconds depending on the length of the blade.
   When grinding the tip of the knife, gently lift the handle to evenly curve the tip of the tip.

4. When the grinding has finished, turn the device off by pressing the 0/I switch to 0.

5. Disconnect the machine from the electrical socket.

Notes

• Always pull the knife with a uniform motion out, not back or back and forth – the result of the sharpening would be uneven.
  Never insert the tip of the knife into the groove and do not press it against the bottom!

• Do not apply heavy pressure and always grind clean blades to avoid premature wear of the grinding wheel.

• Always grind knife blades in the sharp angle of the grinding wheel (as defined by the groove shape). Grinding at the wrong angle can destroy each blade.

• After grinding, remove any residual dust from the grinding that has remained on the blade with a damp cloth.

• Knives with smooth blade always slip on both sides – for this purpose grinding lines for the left and right sides are available.

• When you pull the blade, hold the knife in the left-hand drive as far as possible left-handed and right-angled to the right.

• Always test the knife by cutting off the food slice. If it seems blunt, repeat the sharpening procedure until the knife is sharp.

• Take off the residue from residue container after grinding (5).

Warning!
Never use the appliance for more than a few minutes without a break.

Cleaning and maintenance

• Before each cleaning, disconnect the appliance from the mains and allow it to cool down.
• Use only a slightly moistened cloth to clean the device itself.
• Do not use any solvent or abrasive cleaner.
• Do not put the appliance in the dishwasher.
• Take off the residue from residue container after grinding (5).

Warning!
Never immerse the device in water or other liquid!
Wipe the appliance and the power cord with a dry cloth.
