TO CUT THICK GRASS AND WEEDS
For thick grass and weeds move the brush cutter back and forth in long arcs. Continue it until the brush cutter reaches the ground.
TO CUT BRUSHES
To cut the brushes start from the upper side of the brush keeping the blade parallel to the ground. Move gradually downward until the blade reaches the ground.
TO CUT TREE TRUNKS AND BRANCHES

For cutting tree trunks start the brush cutter.
Raise the blade about 2-8 inches above the ground so that the left side of the blade is against the right side of the tree.
Put the left side of the deflector on the tree so that blade should not move up and down.
Put the blade at one point until it starts penetrating the tree trunk.
Now move the blade gently forward until it cuts the tree trunk.
