3.7SPARK ARRESTOR MUFFLER

If the generator is not equipped with a spark arres- tor exhaust muffler and is to be used on any forest covered, brush covered or grass covered unimproved land, a spark arrestor may need to be installed. The spark arrestor must be maintained in effective work- ing order by the vehicle owner/operator.

For assistance in ordering, installing and maintaining spark arrestor exhaust mufflers, contact the nearest Authorized Service Dealer.

Exhaust mufflers supplied by the manufacturer are spark arrestor types. The manufacturer's exhaust mufflers for recreational vehicle generators do not have a spark arrestor screen, but are of the more effi- cient “toroid” or “swirl” type. To remove carbon and combustion deposits from such mufflers, remove the plug from the muffler and run the engine for approxi- mately 15 minutes. Shut down the engine, let the muffler cool and install the plug.

Be sure to reinstall the muffler plug tightly. Engine vibration could cause a loose plug to fall out. Without the plug in place, hot engine exhaust is directed out the opening. This hot exhaust, depending on the installation, could be directed to areas not able to withstand the extreme heat such as wooden floor boards or other flammable material. This could result in a fire.

3.8CLEANING THE GENERATOR

Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and mois- ture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.

When moisture is allowed to remain in contact with windings, some of the moisture will be retained in voids and cracks in the insulation. This causes a reduced insulation resistance and will eventually cause problems. Dirt will make the problem worse, since dirt tends to hold moisture in contact with windings. Salt (as from sea air) also will worsen the problem since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.

Do NOT use a forceful spray of water to clean the generator. Water will enter the generator interior and cause problems, and may also con- taminate the generator fuel system.

3.9BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use. The generator battery should be inspected as follows:

‹3.9.1 WEEKLY

•Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.

•Check the battery fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries.

‹3.9.2 EVERY SIX MONTHS

•Have the state of charge and condition checked. This should be done with an automotive-type bat- tery hydrometer.

NOTE:

Servicing of the battery is to be performed or supervised by personnel knowledgeable of batter- ies and the required precautions. Keep unauthor- ized personnel away from batteries.

Damage will result if the battery connections are made in reverse.

02010-2, 04164-3 specifications

Guardian Technologies has made a significant impact in the air purification industry with its range of innovative products, particularly the models 02010-2 and 04164-3. These air purifiers are designed to enhance indoor air quality by leveraging advanced technologies, making them popular choices for both home and office environments.

The Guardian Technologies 02010-2 is an impressive model known for its portable design and effective purification capabilities. It features a 3-in-1 air cleaning system that includes a HEPA filter, a charcoal filter, and a UV-C light. The HEPA filter is essential for capturing allergens such as pollen, dust mites, and pet dander, making it ideal for allergy sufferers. The charcoal filter helps eliminate odors, capturing smoke and volatile organic compounds, while the UV-C light helps reduce germs and bacteria, ensuring a cleaner atmosphere.

This model is compact, allowing it to fit seamlessly into small spaces, while still providing powerful purification performance. With a whisper-quiet operation, it can be used in bedrooms or workspaces without causing disruption. Additionally, it features an adjustable fan speed, enabling users to customize the airflow according to their preference, along with an energy-efficient design that helps reduce power consumption.

On the other hand, the Guardian Technologies 04164-3 introduces a more advanced air purification system with similar foundational features but enhances the user experience with added functionalities. This model typically incorporates a combination of a HEPA filter and a UV-C light as well, but it often boasts smart capabilities. These may include an air quality sensor that helps monitor particulate levels in real-time, automatically adjusting the purification level when needed. This intelligent feature ensures that the air quality remains at optimal levels without requiring constant manual adjustments.

Both models prioritize user convenience, sporting features like filter replacement indicators, ensuring timely maintenance of the purification system. They are designed for ease of use and portability, allowing consumers to move them effortlessly from room to room.

In summary, Guardian Technologies’ models 02010-2 and 04164-3 stand out in the air purifier market due to their advanced filtration systems, ease of use, and smart technologies. These air purifiers are key investments for anyone looking to improve their indoor air quality effectively.
