CAUTION!
How to judge whether the battery is destroyed or the impeller is jammed?
1. The impeller suddenly is choked after it worked in a very short time. Turn off the button, and
connected the electric cleaner to the civil electricity by means of the charger. lf the Green LEO
is on, it proves that the battery is destroyed (the solution is referring to the step of how to re-
place the destroyed battery group); if the Red LEO is on, start the power of P1111 to see whether
the impeller will be rotating or not. lf not, it proves that the impeller is jammed. (The solution is
referring to how to resolve the problem that the impeller is jammed).
2. The Green LEO indicator is on after it is charged. Start the power, whereas the impeller does
not work; turn off the button.
a. Connect the charger, and press the button to check whether there is the sound of impe-
ller operation. lf it product "Kaka" sound, it proves that the impeller is jammed(the solution is
referring to how to resolve the problem that the impeller is jammed).
b. Connect the charger, press the button to check whether the impeller works normally.
Turn off the button, and if the Green indicator is on, pull charger off the P1111 electric cleaner.
Start the power again. lf the impeller still does not work, it proves that the battery is destroyed.
c. Using the voltmeter to judge whether the battery is destroyed or the impeller is obstacle.
Firstly charging the battery for more than 1O minutes. Pull the battery out the P1111 electric
cleaner, and measure the voltage of the battery. lf it is "O", the battery is in dysfunction; if it is
not "O", it proved that the impeller is jammed.
3. Oirectly rotate the impeller until it can be moved smoothly(Referring to how to resolve the
problem that the impeller is jammed), and have the battery full of electricity. The battery is
destroyed if the impeller does not rotate.
