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.

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 waterbased 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.

MACHINE OPERATING INSTRUCTIONS
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.
How To Clean A Larger Area Of Carpet See Fig. 8
To clean a larger area of carpet, follow this procedure:
1. Begin at the right-hand corner of the carpet.
2. Make a pass halfway along the edge of the carpet.
Pull the tool backward at a steady speed.
3. Move to the edge of the carpet. Make another pass 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.
7. Make a pass halfway along the edge of the carpet.
8. As you make passes, repeat one inch of the area already cleaned.
9. Make more passes until all of the room is cleaned.
CAUTION: ALTO U.S. Inc. will not be held liable for damage to the carpet, or poor results because of the operator's lack of ability.
