Loosen the locks on the sewage tank cover and manually open it to access the battery compartment. Install the black end of the battery connector to the negative electrode of the battery. Then, install the red end of the connector to the positive electrode. When fastening the bolts, ensure the installation tool does not touch both positive and negative electrodes simultaneously to prevent damage. After tightening, install the protective sleeve on the battery connecting line on the bolt. Manually lower the lock of the sewage tank and close it securely. Verify that the handle of the sewage tank cover is fastened.

Prepare the suction squeegee and manually lift it. Loosen the two handles on the suction strip. Grasp the two handles by hand and lift them together with the two flat pads to be installed on the fixing plate of the suction squeegee. Hand down the suction squeegee and tighten the handles on both sides. Insert the dirt suction hose into the suction pick joint. Adjust the height and angle of the suction squeegee for optimal performance.
