CLEANING TIPS
. . .
GO
SLOW
on very dirty carpet
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”
of
the carpet
fibers
It
will go away when vacuumed

Be
sure
to
overlap enough
to
prevent
WORK AWAY
from the power source
if
possible Begin cleaning next

This will allow you
to
always make turns

If
it becomes
necessary
to

SPINNER
REMOVAL
To
avoid the possibility of the spinner
assembly seizing on the rotary
