Protective devices of motor
1. There is a temperature controller designed in the body
of cleaner motor, which can automatically cut off the
power supply of motor to prevent overheating. When the
air-inlet or air-outlet pipe is overloaded or blocked, the
temperature of motor rises, then the temperature con-
troller cuts off the power supply of motor automatically
to make the motor cool, preventing the cleaner from
being damaged.
2. If the temperature controller is cut off, stop the cleaner
immediately and pull out the power plug to make the
cleaner cool, and check and remove the hair roll or
other roll-like rubbish blocking the air inlet (including the
hose and the spile), and replace the filter HEPA or filter
gauze when necessary.
3. After cooling the motor for 30mins, plug in the power
plug and check whether the temperature controller has
been reset. If the power supply of the cleaner hasn’t
been cut off, the temperature controller of the motor
won’t be reset even when the motor has become cool.
Maintenance of the Cleaner
1. All the day-to-day maintenance and repair jobs should
be done after the power plug has been pulled out.
2. Frequently remove the rubbish from the dust barrel, so
as to avoid the failure of the cleaner.
3. Never wipe the surface of the cleaner with gasoline or
oily liquid. Wipe it with water or neutral detergent.
Caution:
be sure to wring out the wiping cloth dry for
wiping, it is prohibited for water to infiltrate into electrical
elements of the cleaner.
4. When the cleaner is placed idle not in use, it should not
be put directly in the sun or in a damp place.
Storage of the Cleaner
1. Upon the completion of the operation of the cleaner, turn
off its power supply, and pull the power plug out of the
power socket, then step on the cord reeling button to reel
in the power cord fully. Hang the floor brush onto the floor
brush hook.
2. Place the cleaner in the dry indoor environment.
Cleaning of the Dust Barrel
Remove the rubbish in the dust barrel frequently to avoid
the failure of the cleaner.
1. Clean the dust barrel only after the power plug of the
cleaner has been pulled out;
2. Put the dust barrel over the rubbish bin (bag), press down
the releasing button of the dust barrel, the bottom cover
of the dust barrel will automatically fall down, and clear
and empty the dust barrel, as is shown in Figure (8).
Cleaning of front filter for motor:
Warning:
please make sure the power supply of the clean-
er has been cut off before carrying out the following steps:
1. Pull out the power cord plug of the cleaner from the
power socket.
2. Press down the handle of the dust barrel to remove the
dust barrel, and remove the cover of the front filter for
motor, and then use the brush to clean the filter (sponge
and filter gauze with composite coating) or place it
under the cock to clean.
Caution:
It is normal that the white central filter in the dust barrel
may change color, which cannot affect its filtration
performance. If the hose and the central filter are difficult
to clean, we recommend that you use water to flush them;
however, please be sure to place them in the dry air for at
least 24 hours after they are flushed by water.
Key Points:
Please note: when the dust collecting barrel or the filter
cover is not installed in place, the operation status will be
invalid, and the cleaner will have no dust absorption capacity.
At this time, you need to check carefully whether the dust
collecting barrel and the filter cover have been installed in
place.
Caution:
please keep the suction passage unobstructed,
otherwise the motor may become overheating or even be
damaged.
Replacement of rear filter for motor
The rear filter for motor is installed behind the air outlet
grid, which cannot be washed due to the materials used.
When the surface is jammed seriously by dust, the filter
should be replaced by a new one to maintain enough
suction force. (Figure 9).
