,
A temperature limiter switches the the
vacuum cleaner off automatically if it
gets too hot. The warning light , will
then come on to indicate "Warning -
Overheating".
This can occur if, for instance, large
items block the suction wand or when
the dustbag is full or contains particles
of fine dust.
A heavily soiled exhaust or dust
compartment filter can also be the
cause of overheating.
In this case, turn off the vacuum
cleaner using the On-Off switch.
After removing the cause, wait for
20 - 30 minutes, so that the vacuum
cleaner can cool. After the cool down
period, the vacuum can be used.
