CHANCEE K68 - Chapter 3 Checks and Adjustments Before Using the Machine; 3.1 Check Items; 3.2 Adjustment Items

2.2.2 Connecting the battery cords
 Open the sewage tank and check whether all the cables on the batteries are connected and tightened.
 Connect the battery poles. Pay attention to the polarity.
 Close the sewage tank.
Chapter 3 Checks and adjustments before using the machine
3.1 Check items
3.1.1 Checking the water volume in the clean water tank

Make sure that there is sufficient water in the clean water tank before work. Do NOT do
the cleaning without enough water, or dust may be sucked into the suction motor leading
to loud noise and low working efficiency.
3.1.2 Checking the water level in the sewage tank
 Pay special attention to the water level in the sewage tank. When the floating balls are in
the highest position, discharge the sewage tank immediately or the suction motor will be
burnt.
3.1.3 Checking the voltage of the batteries

When the general switch is turned on, the current voltage of the batteries will be
displayed on the voltmeter. If the last bar of the voltmeter is flashing, the power is
insufficient and please charge the batteries immediately.
 Note that deep discharging (e.g. frequently using the machine when the voltage is lower
than 21 V) will reduce the service life of the batteries.
