MAINTENANCE

Replacing the Air Filter

If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a dirty air filter, the spark plug can become fouled. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).

Check the air cleaner daily or before starting the engine. Check for build-up of dirt and debris around the air cleaner system.Keep this area clean. Also check for loose or damaged components. Replace all bent damaged air cleaner components.

Cleaning/replacing the air filter is carried out as follows:

Briggs and Stratton engine

The air filter is replaced as follows:

1.Pull up the handle on the air filter cover, unhook and turn towards the engine.

2.Remove the air filter cover.

3.Lift out the air filter cartridge from the fan housing.

Replace the filter cartridge if it is clogged with dirt.

IMPORTANT INFORMATION

Do not use compressed air to clean the paper filter.

Filters should not be oiled. They should be assembled dry.
