5. When vacuuming large floor areas, hold the floor
wand attachment parallel to your body and pivot at
your waist while walking (a side-to-side mopping
motion). This motion keeps the upper body and
arms from tiring. (Figure 18)

NOTE: The vacuum motor is electronically thermo
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.
6. After cleaning, perform the Machine Maintenance
procedures.
