The California Air Resources Board
(CARB) and STIHL Incorporated are
pleased to explain the emissions control
system warranty on your 2020 and later

In California, new equipment that uses
small off-road engines must be
designed, built, and equipped to meet
the State's stringent anti-smog
standards. STIHL Incorporated must
warrant the emissions control system on
your small off-road engine for the
periods of time listed below provided
there has been no abuse, neglect or
improper maintenance of your small off-
road engine or equipment leading to the
failure of the emissions control system.
Your emissions control system may
include parts such as the carburetor or
fuel-injection system, the ignition
system, catalytic converter, fuel tanks,
fuel lines (for liquid fuel and fuel vapors),
fuel caps valves canisters, filters,
clamps and another associated
components. Also included may be

emission-related assemblies.
Where a warrantable condition exists,

warranty coverage if your small off-road
equipment engine or a part has failed
