OPERATION
5. Carefully install the batteries into the battery
compartment tray and arrange the battery posts as
shown (Figure 5) . Secure the batteries with strap
provided (Figure 4).
ReadySpace® Cleaning: Use this technology to clean
visible soils on a daily basis or as needed to maintain a
high level of carpet cleanliness. ReadySpace cleaning
may be used during normal business hours because
the carpet is dry in less than 30 minutes. Drying time
may vary due to carpet type and climate conditions.
NOTE: Before ReadySpace cleaning, first use
restorative extraction cleaning if carpets are heavily
soiled. Then begin your ReadySpace cleaning
program.
HOW THE DUAL TECHNOLOGY WORKS
FIG. 4
6. Connect the cables to the battery posts in as
shown (Figure 5), RED TO POSITIVE (+) and
BLACK TO NEGATIVE (--).
Restorative Extraction Cleaning: Water is sprayed
directly onto the carpet. As the machine moves
forward, two counter--rotating chevron brushes agitate
the solution deep into the carpet fibers. As the machine
continues to move forward, the vacuum shoes recover
the dirty solution out of the carpet.

DUAL CLEANING TECHNOLOGY
The machine offers two cleaning technologies,
Restorative Extraction and Soil Transfer Extraction,
which is referred to as ReadySpaceR cleaning. By
using both technologies, you can easily develop a
cleaning program to greatly extend the use-life of your
carpet. With the simple exchange of two rollers or
brushes, you can easily switch from one technology to
the other.
Restorative Extraction Cleaning: Use this technology
periodically to thoroughly clean to the base of the
carpet. The amount and type of daily traffic are
important factors to determine how often restorative
extraction should be performed. This type of cleaning
should be planned in advance to allow enough time for
the extracted carpet to dry.

Brush #2
ReadySpace® Cleaning: Water is sprayed directly on
two counter--rotating nylon fiber rollers, not the carpet.
Then much of the water is removed from the rollers
using two vacuum shoes, leaving the rollers damp. The
damp rollers then agitate the carpet, working both sides
of the carpet fiber, at the same time transferring the soil
to the rollers. Again, hot rinse water is sprayed on the
soiled rollers allowing the two vacuum shoes to easily
extract the soil from the rollers.

OPERATION
FILLING SOLUTION TANK
OPERATING THE MACHINE
Fill the solution tank with hot water, 140°F / 60°C
maximum (Figure 12). The solution tank capacity is 32
gal / 121 L.
Before operating the machine, pre-spray the carpet with
a commercially available cleaning agent (Figure 13).
For Restorative Extraction Cleaning and Accessory
Tool Cleaning: For best cleaning results, it is
recommended to pre-spray the carpet with a
commercially available cleaning agent rather than
adding the cleaning agent to the solution tank (Figure
13).
ATTENTION: Only use commercially available
cleaning agents in solution tank. Machine damage
due to improper agent usage will void the
manufacturer’s warranty.
For ReadySpace Cleaning: Do not add cleaning
agents to solution tank. Cleaning agent MUST be
pre--sprayed on the carpet (Figure 13).
WARNING: Fire or Explosion Hazard. Never
Use Flammable Liquids.
FIG. 13

CIRCUIT BREAKERS / FUSES
ACCESSORY TOOL OPERATION
The machine is equipped with two resettable circuit
breakers and two fuses to protect the machine from
damage. If a breaker should trip, determine the cause,
allow the motor to cool then reset the circuit breaker
button.
The circuit breakers and the fuses are located inside
the battery compartment near the hour meter (Figure
