Use of knapsack string grass trimmer and brush cutter-How to operate?

1. Make sure that the nylon rope of the grass trimmer head extends 5-10cm outside the trimmer head when grass cutting with the trimmer head. It will affect the usage life of the gasoline engine due to the large load because of the nylon rope too long, and cause damage to the fender; If too short, It will reduce the work efficiency.

2. The nylon rope will be worn and shortened during normal using. As long as you make the trimmer head gently touch the ground, the nylon line will be automatically thrown out and stretched. If the length is not enough, it can be touched against the ground several times. Until the length of the nylon line is 5-10cm outside the trimmer head. After the nylon rope is used up, the grass trimming head can be disassembled, and the new nylon line can be wrapped around the rope pulley, and assembled back.

3. Don't extend the entire blade into the grass when mowing with a blade. For most lawns, it is enough to extend the half of diameter of the blade into the lawns. For the grass with hard stems it is enough to extend the 1/3 of diameter of the cutting blade into the grass.

4. When cutting a bush with a blade, it should generally be cut in the same horizontal surface along the perimeter of the bush. First make a slit from the direction the bush fell when cutting thick shrubs, with a depth of about 1/3 of the diameter of the bush, and then cut the bush from the other side. This cutting way ensures that the blade is not clamped during the cutting and also controls the direction the bushes fell.
