Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Clean the air cleaner once every 3 months or 25 hours
of operation, whichever comes first. Replace the air
cleaner every two years or 250 hours, whichever
comes first. Service more often if operating under dirty
or dusty conditions. Replacements are available at
your local Sears service center.
To service the air cleaner, follow these steps:
1. Press latch tabs on top of air cleaner cover, and
remove cover.
2. Carefully remove air cleaner from base.
3. Clean air cleaner by tapping it several times on a
hard surface to remove dirt, or blow compressed
air (not to exceed 30 psi) through air cleaner from
clean side that faces engine.
NOTE: NEVER try to brush off dirt. Brushing will force
dirt into the fibers.
