Release handle by stepping on pedal and lowering handle until motor starts.
To lower the handle further, step on pedal again and lower handle as much as
necessary (fig 4).
Use short back and forth strokes to cover small areas at on time.
To switch off raise handle to vertical position.
The necessary time to properly clean a carpet depends on the carpet thickness
and the amount of soil.
To store your upright, roll the cable trying not to twist it and then, either hang it
from the upper hanger of the handle tube (if so equipped), or roll it over both
hangers of the handle tube and fasten it with the clip integrated to the plug.
HEIGHT ADJUSTMENT
The upright has an infinitely variable height adjustment that raises or lowers the
front of the unit. This will allow for better contact with the carpet as needed.
On short or industrial carpet the adjustment knob should be placed to the left,
on shag or heavier rugs the knob should be placed to the right.
To displace knob, pull handle tube backwards until the front is off the ground.
