If any emission related part on your
engine is defective, the part will be
replaced by STIHL Incorporated at no
cost to the owner. Any warranted part
which is not scheduled for replacement
as required maintenance, or which is
scheduled only for regular inspection to
the effect of "repair or replace as
necessary" will be warranted for the
warranty period. Any warranted part
which is scheduled for replacement as
required maintenance will be warranted
for the period of time up to the first
scheduled replacement point for that
part.
Diagnosis
You, as the owner, shall not be charged
for diagnostic labor which leads to the
determination that a warranted part is
defective. However, if you claim
warranty for a component and the
machine is tested as non-defective,
STIHL Incorporated will charge you for
the cost of the emission test. Mechanical
diagnostic work will be performed at an
authorized STIHL servicing dealer.
Emission test may be performed either
at STIHL Incorporated or at any
independent test laboratory.
Warranty Work
STIHL Incorporated shall remedy
warranty defects at any authorized
STIHL servicing dealer or warranty
station. Any such work shall be free of
charge to the owner if it is determined
that a warranted part is defective.
Any manufacturer-approved or
equivalent replacement part may be
used for any warranty maintenance or
repairs on emission-related parts and
must be provided without charge to the
owner. STIHL Incorporated is liable for
damages to other engine components
caused by the failure of a warranted part
still under warranty.

emission-related warranted parts:
Carburetor
Choke (Cold start enrichment system)
