uled for replacement as required maintenance (“Maintenance Parts”), are

General Conditions

Repair by an Authorized Toro Compact Utility Equipment (CUE) Service

Dealer is your sole remedy under this warranty. Neither The Toro®

Company nor Toro Warranty Company is liable for indirect, inciden-

tal or consequential damages in connection with the use of the Toro

Products covered by this warranty, including any cost or expense of

providing substitute equipment or service during reasonable periods

of malfunction or non-use pending completion of repairs under this

warranty. All implied warranties of merchantability and ﬁ tness for

use are limited to the duration of this express warranty. Some states

do not allow exclusions of incidental or consequential damages, or

limitations on how long an implied warranty lasts, so the above exclu-

sions and limitations may not apply to you. This warranty gives you

speciﬁ c legal rights, and you may also have other rights which vary from

state to state.

Except for the engine warranty coverage and the Emissions warranty refer-

enced below, if applicable, there is no other express warranty.

The Emissions Control System on your Product may be covered by a sepa-

rate warranty meeting requirements established by the U.S. Environmental

Protection Agency (EPA) or the California Air Resources Board (CARB).

The hour limitations set forth above do not apply to the Emissions Control

System Warranty. Refer to the California Emission Control Warranty State-

ment printed in you operator’s manual or contained in the engine manufac-

turer’s documentation for details.
