UPHOLSTERY CLEANING
Optional accessories are required for upholstery
cleaning (See page 14).
This machine cleans most synthetic upholstery very
well. Fabrics like Herculon and synthetic velvets will
clean with excellent results. Extraction is not
recommended for most cottons, silks, wools or natural
fiber velvets. Check the cleaning instructions sewn in
the furniture by the manufacturer for further
instructions. Extra caution should be taken with
furniture that has been re–upholstered. Any material
under the new upholstery may bleed and discolor the
new fabric.
1.
Vacuum the upholstery before cleaning.
2.
TEST THE FABRIC FOR COLORFASTNESS.
Pour a small amount of cleaning solution on a
white cloth. Hold the damp portion of the cloth
against an area of upholstery which is hidden from
view. Hold it there for 60 seconds. If no color
transfers to the cloth, it should be safe to clean.
However, always clean at your own discretion.
3.
Remove the short vacuum hose from the recovery
dome.
4.
Connect the accessory vacuum hose to the
recovery dome and to the hand tool.
5.
Connect the solution hose to the upholstery
connection, located above left wheel, and to the
hand tool.
6.
Turn on the MASTER switch.
7.
Clean with the hand tool using as little cleaning
solution as possible. Overlap your strokes to
avoid streaking. Go over clean areas using only
the vacuum to get fabric as dry as possible.
8.
When you are finished, turn off the MASTER
switch, drain the recovery tank, and disconnect the
vacuum and solution hoses.
ATTENTION: Relieve pressure before
disconnecting hose by squeezing Hand Tool
trigger for five seconds AFTER turning off
MASTER switch.
9.
Rinse the recovery tank and the recovery dome
thoroughly to prevent odor buildup inside the tank.

chassis. (The vacuum tool will pivot upward
with the tanks).
To keep your machine in top condition, perform these
preventive steps at the intervals indicated.
1.
Thoroughly rinse the recovery tank, the recovery
dome and the brush after every use.
2.
Clean the solution tank filters and standpipe

maximum. Hold a bucket under the spray jets to
catch the spray, turn on the MASTER switch, and
push the CARPET CLEANING button until the
acetic acid solution begins to spray through the
jets. Allow the solution to remain in the system
overnight in above freezing temperatures. Later,
drain the solution, then run 11 L (3 gal) of solution
through the system to flush out impurities.

not covered by warranty. To avoid pump damage,
always run the pump dry before exposing the extractor
to freezing temperatures.
