SECTION ONE: MACHINE SETUP & OPERATIONS
I. Setting Dilution Ratio on
Chemical Injector
Before operating machine, you must
determine the recommended dilution ra-
tio for the traffic lane prespray detergent
you'll be using. The machine's prespray
system comes preset for High-Flow
Prespray. If the dilution ratio of your
prespray detergent is different, you must
reset your chemical injector (figure 1).
Each machine comes with 14 color-
coded injector tips (figure 2). These
tips screw into the top of the injector
and determine the dilution ratio of
your prespray.
A. Removing and Replacing
Injector Tip
1. Carefully remove chemical line
from top of injector (figure 1).
2. Unscrew color-coded injector tip
from top of injector.
3. Use the dilution ratio chart (figure
3) to determine the injector tip for
your prespray.
4. Screw in new injector tip.
5. Reattach chemical line.
II. Pre-Extraction
A. Chemicals:
• Defoamer: Fill defoamer bottle (fig-
ure 1) with a dilute liquid defoamer.
• Traffic Lane Prespray Detergent: Fill
prespray bottle (figure 1) with traf-
fic lane prespray.
• Spotting Bottle (figure 1): Mix 1/4
traffic lane prespray detergent and
3/4 water. Shake well.
