protected. When the machine senses excessive motor
overload, the motor will automatically function at a low
speed for a few seconds until the motor cools. Should
this happen while operating, check to see if filter bag is
full. If bag is not full, inspect vacuum hose, wand, floor
tool and filters for obstruction.
