INTRODUCTION
• The Model 515 is an extractor for cleaning carpet. When used with a floor tool, the machine applies cleaning
solution to the carpet and removes the dirty solution and soil from the carpet.
• The extractor has controls to start the pump for the solution and the motor for the vacuum. The floor tools
have controls to release the solution and to operate the brush.
• The extractor has a demand pump. The pump starts when the solution lever on the floor tool is activated.
The pump stops when the lever is released.
NOTE: When using the extractor to clean carpets, follow this procedure:
1. Do not walk on freshly cleaned carpets for at least four hours or until the carpet is dry to touch.
2. Do not remove aluminum or plastic pieces that have been placed under the legs of furniture until
the carpet is dry.
3. Do not allow children or pets to crawl or walk around on the damp carpet.
4. Vacuum right after the carpet is dry and then vacuum the carpet once a week as needed.

HOW TO PREPARE THE MACHINE FOR OPERATION
To prepare the machine for operation, follow this procedure:
1. Connect the vacuum hose to the hose connector
on the extractor and to the end of the vacuum
tube on the floor tool.
2. Connect the solution hose to the extractor and
the floor tool. To fasten the quick disconnect
fitting, slide the knurled collar on the female
coupling away from the opening. Push the male
coupling into the female coupling. See figure 4
WARNING: Do not use water that is hotter than
140°F.
3. Before moving the extractor onto the carpet, put
clean hot water into the solution tank.
4. Add a cleaning chemical, such as Clarkare
Extractor Concentrate, to the hot water. For the
correct amount, follow the directions shown on
the container.
5. If the extractor removes an excess amount of
foam from the carpet, add a de-foamer such as
Clarkare® De-foamer Concentrate to the recovery tank. The amount needed will vary according
to the amount of detergent already in the carpet.
CAUTION: To prevent damage, use a water-
based de-foamer rather than an
oil-based de-foamer.
CAUTION: Do not leave the extractor or
other cleaning machines or tools
on the carpet when not in use.
Cleaning solution in the machines
and tools can leak onto the carpet and cause light spots or stains.

How to Clean an Area of Carpet See Figure 7
WARNING: Do not use water that is hotter
than 140°F.
To clean an area of carpet, follow this procedure:
1. Start the pump for the solution and the motor for the
vacuum on the extractor.
2. Begin at the right-hand corner of the carpet.
3. Hold the floor tool at the angle that gives the best
vacuum seal between the tool and the carpet.
4. Apply pressure to the lever for solution release. Pull
the tool toward you at a slow, steady speed. To
remove as much solution as possible, release the
lever before you stop moving backward.
5. To clean the edge of a room, move the tool along the
baseboard until the edge of all the carpet is cleaned.
6. To clean a small area of carpet, clean the carpet in
sections three feet square. As you make more
passes, repeat one inch of the area already cleaned.
7. To remove more liquid from the carpet, make passes
over the area already cleaned, but do not apply
pressure to the lever for the solution.
Figure 7
How To Clean A Larger Area Of Carpet See Fig. 8

next to your first pass.
4. As you make more passes, repeat one inch of the
area already cleaned. If you use a power brush tool,
repeat one inch of the area already cleaned by the
brush. Make each pass four inches different in length
to prevent making a line in the center of the carpet.
5. Make more passes until half of the carpet is cleaned.
To remove more liquid from the carpet, make passes
over the area already cleaned, but do not apply
pressure to the lever for the solution.
6. Move to the right-hand corner of the part of the carpet
not yet cleaned.
