Observe the following guidelines, while cleaning:
WARNING:
Always use defoamer if foaming occurs.
Foam will suspend large particles which
may damage vacuum(s), as well as allow
liquid into the vacuum motor(s).
1. Before proceeding, make certain that the nozzle is functioning
properly.
a. To check, hold the hand tool about one foot above the
surface to be cleaned and open the hand tool valve. A full
spray should be observed form the cleaning nozzle.
b. If the nozzle is not showing a full spray pattern, adjust
nozzle for proper pattern, clean, or replace nozzle.
2. Normally, chemical is applied on the push stroke of the hand
tool when cleaning. Vacuuming is done on the pull stroke.
For heavily soiled carpets the hand tool may be used in a
scrubbing manner, applying chemical in both push and pull
strokes. Always
fi
nish up an area with a vacuum pull stroke.
3. When cleaning, keep the working opening (hand tool mouth)
fl
at on the surface being cleaned. Keep the hand tool moving
when the valve is open.
WARNING:
Improper discharge of waste may damage
the environment and be illegal. The United
States Environmental Protection Agency
has established certain regulations regard-
ing discharge of waste water. Also, city and
state regulations regarding the discharge
may be in effect in your area. Understand
and follow the regulations in your area.
Be aware of the environmental hazards of
chemicals that you dispose.
