X. Preventing Forest, Brush and
Grass Fires
Local, state and federal laws may require use of a spark
arrester to prevent fires. For example, it is a violation of
California Public Resources Code (section 4442) to use or
operate engine on any forest-covered, brush-covered or
unimproved grass-covered land unless engine is equipped
with a spark arrester. Spark arrester must be maintained in
effective working order by owner and/or operator.
To determine if your engine has a spark arrester, locate the
muffler on your engine. For example, the muffler discharge
will have a spark arrester cover that reads “Screen Type
36085”.
If your engine does NOT have a spark arrester, you may
purchase one from your Authorized TecumsehPower
Servicing Dealer. In some cases the muffler may need to
be replaced to allow the spark arrester to be installed.
XI. Maintenance Intervals
Maintenance is one of the most important things that
you can do to extend the life of your TecumsehPower
engine. If you are unable to perform maintenance intervals
yourself, contact your nearest Authorized TecumsehPower
Servicing Dealer. Find them on our website at
www.TecumsehPower.com or call TecumsehPower
Company at 1-800-558-5402 for additional information.
