Operating time is
short even after
charging.
Is the room temperature lower than
5 °C or higher than 34 °C?
Use the vacuum cleaner where the ambient tem-
perature is between 5˚C to 34˚C. The operation time
may be shorter or the charging time may be longer.
P.E-8
P.E-11
P.E-12
Are you using the vacuum cleaner in a
cold place?
Leave the vacuum cleaner in an area where
the ambient temperature is between 5 °C and
34 °C. Wait for the vacuum cleaner to warm
up, and then try again.
P.E-8, E-11
P.E-12
Did you leave the vacuum cleaner unat-
tended for a long period of time without
charging it?
The battery capacity might be temporarily
recovering poorly. Repeat the procedure of
using the cleaner until the battery is exhaust-
ed and charging fully about 2 to 3 times.
P.E-11
