GROUNDING INSTRUCTIONS
Machine must be grounded. If it should
malfunction or breakdown, grounding provides a
path of least resistance for electrical current to
reduce the risk of electrical shock. This machine
is equipped with a cord having an
equipment–grounding conductor and grounding
plug. The plug must be plugged into an
appropriate outlet that is properly installed in
accordance with all local codes and ordinances.

APPLICATION
INSTALLING THE LIQUID CLEANING AGENT
(FORMULA 710) CONTAINER
“Formula 710 Multi-Surface Acid Cleaner”agent is
specifically designed and recommended for use in this
machine. It is formulated to clean soap scum, hard
water scale, and soils typically found in restrooms,
showers, swimming pool areas, etc. Use only on
water-resistant surfaces. To order the “Formula 710
Multi-Surface Acid Cleaner”or an approved substitute,
contact your Tennant supplier.
ATTENTION: Use of unapproved or inappropriate
chemicals may cause damage to machine and
surfaces and could void your warranty
FOR SAFETY: When using machine, follow
mixing, handling, and disposal instructions
provided on chemical container instructions and
Material Safety Data Sheets (MSDS).
1. Remove cap from the blue injector tube. Do not
misplace cap (Figure 1). Use cap to prevent injector
tube from clogging when machine is not in use.
FIG. 1
2. Select the desired metering tip (Tips supplied with
machine) and thread tip into the blue injection tube
on the machine (Figure 2). Dispensing rates
shown are for the “Formula Multi-Surface Acid
Cleaner”agent. Substitute agents may have
different dispensing rates. The orange tip is
factory installed on .
Orange Tip= 15ml./L (2 oz. per gallon)
for light cleaning.
Red Tip= 30ml./L (4 oz. per gallon)
for medium cleaning.
Blue Tip= 44ml./L (6 oz. per gallon)
for heavy cleaning.

foam in the recovery tank. Pour a recommended
foam control solution into the recovery tank if
excessive foam appears. This will prevent vacuum
motor damage (Figure 26).
FIG. 26
ATTENTION: Excessive foam buildup will not
activate the float shut-off screen.
9. If the squeegee begins to trail water while
operating, the recovery tank must be drained (See
DRAINING TANKS).
10. When finished cleaning, turn the machine off and
wipe off the blower and vacuum hoses. Store the
hoses on the machine after cleaning.

recovery tank before proceeding to the next area to be
cleaned.
DRAINING TANKS
When finished cleaning, the recovery tank should be
drained and cleaned. If you have left–over rinse
solution, it can remain in solution tank for the next use.
Drain the solution tank when storing the machine for
extended periods or when transporting machine.
FOR SAFETY: When servicing machine, unplug
cord from wall outlet.
DRAINING RECOVERY TANK
Recovery tank must be emptied prior to refilling the
solution tank.
1. Turn the machine off, unplug the power cord and
push the machine to the drain site.
