by Exmark. Such routine maintenance, whether performed by
a dealer or by you, is at your expense.

General Conditions

The sole liability of Exmark and Exmark Warranty Company
with respect to this warranty shall be repair or replacement of

product is fit for a particular purpose) are limited to the
duration of the express warranty.
