Briggs Stratton 797704 Pre-cleaner Air Filter

Product Description

The BRIGGS STRATTON 797704 is a pre-cleaner air filter element designed to protect the primary air filter and carburetor on small gasoline engines. It serves as the first stage of filtration, capturing larger debris such as grass clippings, dust, and chaff before they reach the main filter media. This part is installed by small engine technicians and knowledgeable DIYers performing routine maintenance on outdoor power equipment powered by Briggs Stratton engines. Replacing the pre-cleaner at recommended service intervals helps maintain proper airflow and extends primary filter life.

This pre-cleaner is suited for residential outdoor power equipment applications including walk-behind lawn mowers, riding mowers, and similar small engine platforms. It is a direct OEM replacement part, intended for use in scheduled maintenance during seasonal service or whenever the filter shows visible contamination. Technicians typically inspect and replace this component as part of a standard engine tune-up procedure.

Installation Notes

Always stop the engine, allow it to cool, and disconnect the spark plug wire before servicing the air filter assembly.
