When using the well cover cutter for construction, sometimes I feel that the cutting speed is relatively slow and the cutting force is very small. Generally speaking, I feel that I can't cut when cutting. What is the reason for this situation?

1. First look at the cutting piece to see if it is the wrong cutting piece, and then check whether the cutting piece is broken or notched, which may lead to weak cutting. If the cutting piece is OK, continue to look down.

2. Check whether the cutting oil supply circuit is blocked, resulting in poor oil supply.

3. Whether the filter screen at the oil suction port of the oil pump is blocked, so that the oil pump can not suck oil.

4. The oil tank leaks, resulting in less oil.

5. Check whether the cutting transmission valve is broken.

If the above points are checked and the reason is still not found, resolutely contact the official after-sales of the well cover round cutter manufacturer, and they will send professional technicians to carry out all-round investigation
