What is the difference between automatic winding and manual winding?
According to our multiple inspections of the product, it is known that the automatic winding of the machine minimizes the damage rate of the string trimmer.
Because the position of the string trimmer line installation needs to be spaced to make it work properly, the manual winding is easy to cause the surface of the spool to be uneven.
If the interval is too small, the string trimmer will be difficult to work, and the spool will be stuck. And it may cause
the spool to pop out, damage the string trimmer and cause a safety accident.
