2. Main Technical Specifications

3. Operation Instructions

3.1 Placement

The slicer should be placed on a sturdy, flat table or desktop with adequate space for the slicer to operate, maintain, and ventilate.

Power requirements of the slicer: Please make sure the power supply is consistent with the nameplate parameters. The slicer is attached with a standard triangle plug with an earth wire; the power socket must be the standard triangle.

3.2 Unpacking

Prior to installation, please confirm all components are packed with the machine. If anything is missing, please contact the supplier.

3.3 Machine parts and their locations

Attention: For proper use and service, please carefully read this chapter and get familiar with the parts and their locations.

The main parts of the meat slicer are:

• 1. Locking board
• 2. Plastic board
• 3. Grinding stool
• 4. Protect circle
• 5. Presser
• 6. Blade
• 7. Slide bracket
• 8. Table
• 9. Carrier
• 10. Handle bar

3.4 Lubrication

• Turn over the machine, spread lubricating oil on the surface of the square orbit and circle orbit every 7 days.
• Spread food oil on the slide bracket.

Attention: Turn off the switch and cut off the power of the machine when spreading the oil.

3.5 Power wire connection

• The power switch is located on the left side of the machine. The ring light will light up when the "ON" button is pressed, and the slicer is turned on; the machine will be turned off when the "OFF" button is pressed.
• In the power line connection, the equipment power supply needs to be connected to the power grid through an external leakage protection switch with sufficient current capacity. The leakage action value is 30 mA, and the operation time is <0.1 S. (This device is not equipped with this device).
• Equipotential: Equipotential bonding in an electrical appliance connects the exposed metal and conductive parts of the electrical equipment and other devices to the conductors of the artificial or natural grounding body to reduce the potential difference (reduce and prevent the risk of electric shock).

3.6 Test-run the machine without product

• Before initial startup, carefully check the tightness and condition of the blade cover, carrier, blade, and other parts, and apply oil to the surface of the square orbit and circle orbit.
• Press the power switch and confirm the blade is properly rotating.
• Please run for 3 minutes before loading with product.

3.7 Blade grinding

• The round blade of the meat slicer is made of high-quality, wear-resistant steel. The edge of the blade has been sharpened by the manufacturer before sale.
• The blade may dull after daily use. The grinder comes with a sharpening stone that can be used repeatedly. Before sharpening the blade, you should clean the sharpening stone to prevent discoloration to the blade.
• When the sharpener is not working, the grinding stone should be kept away from the blade; when it works, it should get close to the blade.

The method to change the position:

Hold the wheel cover to the proper height, rotate 180°, and then press the locking knob.

Attention: The height of the sharpener is limited by a stud, and elongation of the stud can be adjusted.

The sharpener is equipped with two grinding wheels: one is for sharpening, and the other is for repairing the edge.

Press the button when sharpening the blade, rotate the blade, and press the end of the grinding shaft by hand, allowing the grinding stone to touch the blade. When sharpening the blade, you should press the end of the grinding shaft by hand, allowing the grinding stone to touch the blade.

Attention:

• Slightly press the grinding shaft; it is better to produce little spark.
• Adjust the position of the grinding stone to make the grinding stone locate on the front side of the blade but cannot touch the edge of the blade.

3.7.5 Sharpening

Loosen the stone axis and press the button to make the stone out of the blade, press the button to stop the blade, and observe the sharpening effect.

Check the blade for burrs and ensure that it is sharp. If the blade is still dull, you can repeat the process until you are satisfied.

Attention: Please don't use your finger to test whether the blade is sharp or not, this could result in serious injury!

Clean the steel and grinding stone residue from the machine.

When cleaning the blade, you can remove the protection cover.

Attention: Do not submerge the unit in water or use harsh chemicals for cleaning.

After repeated regrinding, the blade's diameter will be reduced. When the distance between the locking board and the edge of the blade is more than 5 mm, please loosen the screw on the back of the locking board, move the locking board towards the blade and adjust to 2 mm, then tighten the screw.

Attention: The blade needs to be changed when its diameter is reduced by 12 mm.

3.8 Slicing thickness adjustment

• The slicing thickness is the distance between the blade and the locking board.
• Turning the adjustment handle counterclockwise creates a thicker slice; turn the adjustment handle clockwise for a thinner slice.
• When adjusting the thickness of the slice, please remember to eliminate the transmission gap. The solution is to first enlarge the slicing thickness, then decrease to the desired thickness. When adjusting the thickness of the slice to thin, you don't need to eliminate the transmission gap; directly adjust to the desired thickness.

3.9 Change the blade

3.9.1 Remove the blade cover.

• Remove the carrier away from the blade.
• Unscrew the rod from the back of the machine.
• Remove the blade cover.

3.9.2 Remove the sharpener.

3.9.3 Take off the blade

• Unscrew the three screws, remove the blade evenly.
• When installing a new blade, clean the surface around the blade, gradually tightening the three screws until tight.

Attention: When replacing the blade, the machine must be turned off and the power cord removed from the outlet.

Attention: When replacing the blade, please wear protective gloves and take precautions when handling the sharp edges.
