to
avoid
streaking
Be
prepared
to
make two
cleanings
if
carpet is badly soiled
Pre-
spraying may also be necessary
Narrow bands
of
streaking can result
from a plugged THRUSTERJET nozzle
See
servlce sectlon for instructms Pay
more attention
to
using a clean bucket
when filling
solution tank to amd future
problems
Paths, or wide stripes. over the carpet
can occur with certain types of carpets
This
is due to the “lay”
