HOW TO OPERATE THE MACHINE
How To Operate The Chemical Mixing System
(Optional)
The chemical mixing system is designed to automati-
cally mix the cleaning chemical directly from the
manufacturer’s chemical container into the clear water
coming from the solution tank. The chemical control
knob on the control panel is used to select the desired
ratio according to the recommendation of the chemical
manufacturer and the application requirements. The
ratio settings are shown in figure 19.
CAUTION: Do not operate the chemical
pump dry. If the chemical con-
tainer is empty, make sure the
chemical control is in the off
position.
To operate the chemical mixing system, follow this
procedure:
1. Select the proper cleaning chemical for scrub-
bing application.
2. Set the chemical knob to the recommended
setting per the chemical manufacturer.
3. Make sure the recovery tank is empty and then
open the recovery tank.
4. Position the manufacturer’s chemical container
into the bracket located at the front right side of
the solution tank. See figure 18A & 18B
5. Remove container cap and insert bottle adapter
and tighten cap.
6. Slowly close the recovery tank.
NOTE: With the knob turned fully counterclock-
wise, only water will be delivered to the floor.
