Never Operate When;
• the machine has suffered any external damage
• cables or hoses are damaged
• the possibility of damage after dropping the machine
• the machine leaks.
Always Unplug Appliance;
• before re-fi lling with water,
• when it is not in use,
• before cleaning and maintenance
• when leaving unattended.
Safety Precautions;
• Never use the soil extraction method unless you have verifi ed
that the textile fl oor covering and the fl oor itself will suf fer no
damage.
• Special care is required with:
• Floors which can be damaged by water (e.g. wood
fl oors and fl oors of similar material).
• Carpeting secured with adhesive which is not water
resistant.
• Carpeting which is only partially glued down.
• Carpets having a backing fabric sensitive to water (e.g. jute
or jute blends).

How to Operate
Prepare the fl oor
• Before using spray extractor, vacuum carpet thoroughly.
Prepare the spray extractor
• Only use the machine if the voltage stated on the type plate (number of volts) is identical with the available supply and the connector
socket is grounded.
• Check that the fi lter is present in the fresh water tank.
• Mix the cleaning agent in a bucket with cold or hot water (max.
122°F). Measurement: Direct extraction 1% - 3%, pre-spraying 3% 10%.
• Connect the pressure hose to the machine at the quick-relase coupling. Insert the suction hose in the machine. Assemble suction hose
and pressure hose to suction / spray pipe.
• Check that all switches are off.
• Plug in the main supply cable.
Starting up the machine
• Switch on the pressure pump. To avoid damage to pump, be sure the
fresh water tank is full. Pump is not designed for dry running.
• Switch on the suction motor.
Spray extraction with normal soiling
• Pull nozzle slowly backwards (approx. 5 sec./3ft) with slight pressure
on the handpipe. Continue to use spray/extraction method in this
manner, i.e. spray and pick up immediately.
• Shortly before completing each pass, shut off the water supply to
pick up the water last sprayed on.
• The nex t working length should overlap the previous one by .5 in.-1 in.
Spray extraction with heavy soiling
• Carry out spray/extraction a second time, in a crosswise direction if
area permits. This second cleaning phase is only to be carried out on
a totally dry carpet. Note the safety precautions detailed on page 2.
Pre-spraying with heavy soiling
• Using suction / spray pipe:
Pass nozzle fairly quickly over the carpet (approx. 3 sec./3ft) with
the valve open and suction motors switched off.
• Using spray lance:
Connect spray lance to socket for pressure hose. ( Max. pressure
72.5 psi ).
• Using an external spray device:
Spray the entire carpet surface, wetting badly soiled areas more
thoroughly. Allow the cleaning solution time to act, but never allow
it to dry out.
• Then spray/extract with clean water as described in previous section
With very heavy soiling
• Shampoo extremely heavily soiled carpets using a single brush machine.
Foaming
• When using the spray extraction machine, excess foam may occur
in the recovery tank, especially if the carpet has previously been
cleaned using a high foam shampoo. If this occurs add defoamer as
required to the recovery tank.
Cleaning areas with diffi cult access
• Areas of carpeting which are inaccessible to the spray extraction
nozzle, e.g. corners, recesses, edges, under radiators or on stairs, can
be cleaned easily using the manual extraction nozzle.
