CLEANING TIPS

.
.
GO
SLOW
on very dirty carpet
to
avoid streaking.
prepared
to
make
two cleanings if carpet
is
badly
soiled. Prespraying may also be
necessary.
Narrow bands of streaking
can
result
from a plugged nozzle. See service
section for Instructions. Pay more
attention
to
using a clean bucket
when filling solution tank
to
avoid
future problems.
Paths, or wide stripes, over the
carpet can occur with certain types
of
carpets. This is due
to
the “lay”
of the carpet fibers.
It
will go away
when vacuumed.
Be
sure
to
overlap enough
to
prevent
uncleaned stripe.
WORK AWAY
from the power source
if
possible. Begin cleaning next
to
wall.
This will allow you
to
always make
turns away from the cable.
KEEP
THE MACHINE MOVING
when
jets
are “on.” If
it
becomes necessary
to
stop
to
maneuver in a turn or corner,
push the solution switch
to
the

position.
CAUTION:
Overwetting of the
carpet
is
likely,
