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. If the Green LED is
on, it proves that the bettery is destroyed (the solution is referring to the step of how to replace the
destroyed battery group); if the Red LED is on, start the power of P1111 to see whether the impeller
will be rotating or not. If 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 LED indicator is on after it is charged. Start the power, whereas the impller does not
work; turn off the button.
a. Connect the charger and press the button to check whether there is the sound of impeller
operation. If it product "Kaka" sound, it proves that the impeller is jammed (the solution is refe-
rring to how to resolve the problem that the impeller is jammed.)
b. Connect the charger, press the button to check whether the impeller worked normally. Turn
off the button and if the Green indicator is on, pull charger off the P1111 electric cleaner. Start the
power again. If the impeller still does not work, it proves that the battery is destroyed.
c. Using the volltemeter to jusdge whether the battery is destroyed or the impeller is obstacle.
Firstly charging the battery is in dysfunction. Remove the battery from the P1111 electric cleaner
and measure its voltage. if it is not "0", it proved that the impeller is jammed.
3. Directly 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 os electricity. The battery is des-
troyed if the impeller does not rotate.
