A spark arrester is available from your nearest Sears service center. If you need to order a spark attester, please call 1-800-366-PART.

The spark arrester must be serviced every 50 hours to keep it functioning as designed.

If the engine has been running, the muffler will be very hot. Allow the muffler to cool before servicing the spark attester.
