Replace paper element yearly or every 300 hours.
CaUtiOn
Do not wash paper element. Do not use pressurized air to clean or
dry paper element.
NOTE: Operating in a dusty condition may require more frequent
maintenance than above.

Reinstall the foam element and then the paper element on the air
cleaner body.

together the case and air cleaner body.
CaUtiOn
After servicing the air cleaner, be sure all the removed parts are
reinstalled properly in place. Failure to securely fasten together air
cleaner case and air cleaner body may cause dirt or other foreign
materials to enter the engine while it is running, resulting in engine
troubles or failures.

hard starting, or engine smoking. If over the FULL mark on the
dipstick, drain oil to reduce oil level to FULL mark on dipstick.
