Operations

Cleaning

Always use defoamer if foaming occurs. Foam will 
suspend large particles that may damage 
vacuum(s) as well as allow liquid into the vacuum 
motor(s) without activating the float shutoff.

1.

Prior to cleaning, make certain that the nozzle is 
functioning properly.

a.

To check, hold the wand about one foot above 
the surface to be cleaned and open the wand 
valve. A full spray should be observed from the 
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 wand when cleaning. Vacuuming is done on 
the pull stroke. For heavily soiled carpets the wand 
may be used in a scrubbing manner, applying 
chemical in both the push and pull stroke.

3.

When cleaning, keep the working opening (wand 
mouth) flat on the surface being cleaned. Keep the 
wand moving when the valve is open.

4.

The shutoff float inside the vacuum tank will 
impede the vacuum flow when the vacuum tank is 
full. When this occurs, empty the vacuum tank by 
opening the dump valve and dispose of the waste 
in a proper manner. 

5.

Once the vacuum tank has been emptied, you may 
once again proceed with cleaning
