VONCI has introduced a doner kebab slicer tailored for the Turkish market. Equipped with imported German blade assemblies and assembled internally in China, it is an ergonomic and user-friendly handheld device.

Troubleshooting Steps
Some users have reported that the slicer fails to start after being left unused for a long period. For this issue, troubleshooting can be performed from the following aspects:
Check for Oxidation on the Power Plug
When the kebab slicer remains unused for an extended time, the two metal prongs of its power plug may oxidize and interrupt the power supply. You can polish the prongs with sandpaper and reinsert the plug to see if the fault is resolved. Additionally, verify that the power outlet is intact and the power supply is functioning normally.
Inspect the Power Switch
Operating in humid kitchen environments, the slicer’s power switch is prone to corrosion and rust, which leads to poor electrical contact. Replacing the switch will resolve this issue.
Internal Circuit Damage
If both the power supply and the switch work properly, the internal circuit may be damaged. This problem can only be fixed by returning the device for repair. There are various causes for such damage, with irregular post-use maintenance being the most common one.
Internal Damage to the Power Cord
Long-term repeated bending of the power cord can cause internal wire breakage, which requires replacing the power cord. It is recommended to first check the exterior of the cord for obvious creases or damage. If no visible issues can be identified, try gently wiggling the cord while observing the device’s response. During daily use, avoid excessive bending of the power cord, and store it in a naturally extended state to prolong its service life. If none of the above troubleshooting steps work, do not disassemble the internal core components on your own, as this may damage the waterproof structure or cause secondary damage. Contact official after-sales service promptly for professional inspection and repair to ensure the safe operation of the device.
Regular Maintenance Recommendations
To prevent slicer malfunctions and similar failures from recurring, please carry out the following maintenance tasks:
Power-on Test
Conduct a power-on test at least once a month to reduce the risk of internal moisture buildup and oxidation. Always perform the test following the safety instructions in the user manual.
Hygiene and Cleaning
The slicer will become soiled after use. Clean off all grease and oil residues to prevent contamination of the internal circuit and short circuits. After thorough cleaning, place the device in a dry, well-ventilated area. Do not store it casually in a damp kitchen cabinet.
In-depth Maintenance
Perform in-depth maintenance at least once every six months. Unlike routine surface cleaning, in-depth maintenance involves disassembling internal components, lubricating mechanical bearings, and clearing internal dust. This work requires professional expertise, so ordinary users can send the device to official after-sales service for this service.
The above covers all solutions for kebab slicer startup failures. If you use this type of slicer in Turkey, please perform regular maintenance and operate the device safely.
