position of the limit bolts of each brush is as follows (the test plate has been removed):

1. Before adjustment, please make sure that the sweeper has been powered off and the key device has
been unplugged.
2. Adjust the bolt upward to increase the height of the brush from the ground, and adjust the bolt
downward to reduce the height of the brush from the ground.
3. After the adjustment is complete, you can use the key to start the sweeper, and press the sweep
switch to check the working height of the brush.

1. Unscrew the 3 fixing screws of the side brush.
2. Press down the side brush or beat it evenly.
