Service Air Cleaner

The engine’s air cleaner is one of the most important areas to maintain.The engine will not run properly and will be damaged if it is run with a dirty air cleaner system.

Use only genuine Briggs & Stratton parts or their equivalent.The use of replacement parts which are not of equivalent quality may damage the engine.

Clean the foam precleaner every 25 hours and the cartridge every 100 hours of operation. Clean or

replace more often in dusty or dirty conditions.

CAUTION! Never run this equipment without the complete air cleaner system installed on the engine. Failure to do so will result in premature engine wear and significantly reduced engine life.

To service the air cleaner components:

1.Unhook clips on both sides of cover and remove cover (Figure 9).
