Michelin MVC 7.4V Notice D'utilisation page 9

d) When charging is complete, which can take around 5 hours with fully
discharged batteries, the appliance automatically switches to a trickle
charge (maintenance function). Nevertheless, in order to avoid possible
damage to the batteries, do not leave the appliance permanently
connected to the mains adapter (4).
e) Do not recharge the batteries again until the handheld vacuum cleaner's
suction power becomes appreciably weaker and the charge indicator
lamp (7) flashes green.
f) The handheld vacuum cleaner can also be charged directly via the mains
adapter (4). To do this, remove the device plug (5) with a slight twist from
the wall bracket (3) and insert it into the socket on the handheld vacuum
cleaner.
7. OPERATION
7.1. Caution!
The suction opening must always be open and may not be blocked. Blockages
lead to overheating and damage to the motor.
7.2. Note
7.2.1. Make certain that the dust filter (10) is always inserted before using
the appliance.
7.2.2. When vacuuming liquid, do not exceed the MAX marking in dirt
container.
a) Remove the handheld vacuum cleaner from the wall bracket (3) or,
if you are not using the wall bracket (3) remove the device plug (5)
from the socket.
b) If required, place the appropriate nozzle in the suction opening:
- the crevice nozzle (2), to clean narrow and difficult to reach
locations.
- the wet suction nozzle (1) to vacuum up liquids.
7.2.3. After you have vacuumed up liquids, immediately clean the dirt
container. Otherwise, bacteria or mould will build up inside! Ensure
that the dust filter bag (9) is completely dry before using the appliance
again.
