ted force. This reaction can be violent enough that the operator momentary loses control of the

machine. A kickback can occur without warning when the cutter encounters an unseen obstacle

when the blade is running. This is more likely in areas where it is difficult to properly check the

material/area to be cut. For easy and safe cutting, cut the weeds/brush from right to your left.
