How to maintain and service a household wire cutting machine

The maintenance and care of household wire cutting machines are the key to extending the service life of the equipment, ensuring operational safety and the effect of wire cutting. The following provides professional and practical suggestions from four dimensions: daily cleaning, component maintenance, safe operation, and long-term maintenance

I. Daily cleaning and disinfection

Cleaning process

Operation after power failure: Cut off the power supply, unplug the plug to avoid the risk of electric shock.

Disassemble the detachable parts: Remove the blades, feed inlet, discharge tray and other detachable parts. Soak and clean them in warm water and neutral detergent. Avoid scratching with hard objects such as steel wool balls.

Main unit cleaning: Wipe the main unit shell with a damp cloth. Stubborn oil stains can be wiped with a small amount of alcohol, but avoid the motor and circuit areas.

Drying treatment: After cleaning, air dry the components or wipe them dry with a soft cloth to prevent rusting.

Disinfection suggestions

Food-grade disinfectant: If disinfection is required, the detachable parts can be soaked in diluted sodium hypochlorite solution (such as a 1:200 ratio) for 10 minutes, then rinsed with clean water and dried.

Avoid high temperatures: The blade and plastic components should not be boiled at high temperatures to prevent deformation or damage.

Ii. Maintenance of Key Components

Blade maintenance

Regular grinding: After the blade is blunted, it should be gently ground along the original Angle with a professional knife sharder or sandpaper (400 mesh or above) to avoid changing the Angle of the blade edge.

Rust prevention treatment: After drying, a thin layer of edible oil can be applied to the surface of the blade to prevent oxidation and rusting.

Replacement standard: When the blade has notches, curled edges or uneven wire thickness, a new blade should be replaced in a timely manner.

Inspection of transmission components

Belts/Gears: Check the drive belts or gears monthly for looseness or wear. If cracks or slippage are found, replace them.

Lubrication treatment: Add 1-2 drops of food-grade lubricating oil (such as white oil) to the motor shaft and gear meshing points. Do not add too much.

Feed inlet and discharge tray

Clearing blockages: After each use, check if there are any residual vegetable residues at the feeding port. Use a soft brush to remove them to prevent jamming.

Discharge tray positioning: Ensure that the discharge tray is tightly connected to the main machine to prevent displacement during wire cutting.

Iii. Safety Operation Specifications

Check before use

Make sure the blade is securely installed without any looseness or shaking.

Check that the power cord is undamaged and that the plug matches the socket.

Precautions during operation

Pre-treatment of ingredients: Cut ingredients (such as potatoes and carrots) into appropriate sizes (diameter ≤ feed opening). Hard ingredients (such as sugarcane) need to be softened or cut into sections first.

Uniform feeding: Avoid pushing the ingredients directly with your hands. You can use a dedicated feeding rod to prevent your fingers from touching the blade.

Continuous working duration: Do not use continuously for more than 10 minutes at a time to prevent motor overheating.

Exception handling

Motor stop: Immediately cut off the power and check for overload (such as excessive food), blade jamming or power failure.

Odor or smoke: Cut off the power immediately and contact after-sales service for repair. Do not force use.

Iv. Long-term Storage and Seasonal Maintenance

Storage environment

After cleaning and drying, store in a well-ventilated place to avoid rusting of circuit boards or metal parts due to moisture.

Put on a dust cover to prevent dust from entering the motor or transmission components.

Seasonal maintenance

During the rainy season: Power on and run the motor once a month (for 5 minutes) to prevent it from getting damp.

Long-term idleness: Check once every three months. Rotate the blade to confirm there is no jamming. Add lubricating oil if necessary.

V. Common Faults and Solutions

Possible causes and solutions of the fault phenomenon

Uneven thickness of the cut thread, loose or worn blade. Tighten the blade or replace it with a new one

If the motor makes abnormal noise, the transmission components are loose or the bearings are damaged, check and tighten the belts/gears, and replace the bearings

If the discharge is clogged with too much food or the discharge tray is displaced, pre-treat the food and adjust the position of the discharge tray

If the power indicator light is not on or there is a fault with the power cord or socket, check the power cord, replace the socket or contact after-sales service
