,
A temperature limiter automatically
turns the vacuum cleaner off if it gets
too hot. This can occur if large articles
block the suction wand, or if 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.
^ Turn off the vacuum cleaner using the
On/Off switch.
^ After removing the cause of
overheating, wait 20 - 30 minutes so
the vacuum cleaner can cool. After
the cool down period, vacuuming
can be resumed.
