To select a pile height setting:
Turn off vacuum cleaner. Select a pile height
setting by tilting the cleaner back until front
wheels are lifted slightly off the floor.
Slide the adjustment lever to the correct
setting.
There are four (4) pile height settings on the
vacuum cleaner. Use the LOW setting for
most low-pile carpets and bare floor
cleaning (with agitator OFF), and the HIGH
setting for high-pile carpets like shag carpet,
scatter rugs, etc. Use the other settings as
needed for carpet heights in between.
CAUTION
Do not allow vacuum cleaner to remain
in one spot for any length of time
when the agitator is turning. Damage
to carpet may occur.
