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-coveredor
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 "Tecumseh
Screen Type 36085".
If your engine does NOT have a spark arrester, you may
purchase one from your Authorized Tecumseh Servicing
Dealer. In some cases the muffler may need to be replaced
to allow the spark arrester to be installed.
