Warranty Period
The warranty periods will begin on the
date the utility equipment engine is
purchased by the initial purchaser and
you have signed and sent back the
warranty card to STIHL. 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 mainten-
ance will be warranted for the period of
time up to the first scheduled replace-
ment 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 war-
ranty 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.

parts. These warranted parts are:
Carburetor
Choke (Cold start enrichment system)

Spark plug
Magneto or electronic ignition system
