Things to check

[Battery indicator lamp is flashing (about two times per second)]
Is the exhaust abnormally hot?
When continuously operating on "High" in places of high temperature, such as under direct sunlight or in
cars exposed to the sun, the safeguard might operate and the suction power might become weak to prevent
the body motor and battery from overheating.
Is the dust case full of dust?
Is dust stuck in the filters?
Is dust clogging the body air duct?
Is dust clogging the power head or mini power head?
Did you vacuum fine sand or dust?
Is the remaining battery level low?
Is the cleaner set on the charging
station?
When the battery gets hot, the body might stop
automatically to prevent the battery from overheating.
Did you leave the body unattended
for a long period of time without
charging it?
Is the battery exhausted?
The motor is being cooled via air flow, which is normal.
It gets warm due to the flow of electrical current to the control circuit, which
is normal.
Is dust stuck in the filters?
Are the filters thoroughly dried after washing?
Are the clean filter and dust case securely attached?
Is dust clogging the body air duct?

The battery capacity might be temporarily recovering
poorly. Repeat the procedure of using the cleaner until

If the operating time is particularly short even after
charging correctly or maintaining the filters washing
with water, the battery is exhausted. Please consult
with the Hitachi authorized service agent.
