If there is a product quality problem within 1 year since the machine is shipped from our factory, TVX is responsible for solving it and providing the required materials FREE of charge.

Videos or photos of machine nameplates and machine failures or damaged accessories are required.

TVX machines can use lithium batteries, but it is not recommended. Because there is no signal communication between the controller and the lithium battery, the power display of the machine is inaccurate. Under normal circumstances, the TVX machine will alarm when the battery is low, and at the same time, the brush disc will automatically lift up and stop working. Only the drive motor can still run for the customer to drive the machine back to charge, but suddenly the whole machine is powered off during use, and then you can only manually release the battery valve and return the machine to charge.

5. The rubber is worn and aged or foreign matter is attached to the rubber

6. The height (pressure) of the head is not adjusted to the proper position

Check the voltage before using the machine. When the voltage is lower than 24V (T150 is 36V), it cannot be used and must be charged; each time you use it, do not use up the battery completely, and you must charge it when there are only 2 batteries left, otherwise, it will be easy The battery life is shortened, and it will be scrapped if it is serious. When the machine is not used for a long time, in order to prevent the battery from being over-discharged, the battery should be replenished regularly (usually 2 months).

The gears in the gearbox are damaged and need to be replaced.

5. The wire harness between the control panel and the controller is broken, the terminals are loose and fall off, and the pins of the terminals are shrunk

6. The wiring between the controller and the battery is not connected properly.

7. Controller failure (voltage measurement)

8. The insurance burns out
