How to Operate

• Before using spray extractor, vacuum carpet thoroughly.

• Only use the machine if the voltage stated on the type plate (num-ber 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 cou-pling. 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.

• 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.

• 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 next working length should overlap the previous one by .5 in.-1 in.

• 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.

• 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

• Shampoo extremely heavily soiled carpets using a single brush ma-chine.

• 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.

• 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.
