Parts

Parts scheduled for replacement as required maintenance are war­ranted for the period of time up to the scheduled replacement time
for that part. Parts replaced under this warranty are covered for the
duration of the original product warranty and become the property
of Toro. Toro will make the fi nal decision whether to repair any ex-
isting part or assembly or replace it. Toro may use remanufactured
parts for warranty repairs.

Note Regarding Deep Cycle Battery Warranty:

Deep cycle batteries have a specifi ed total number of kilowatt-
hours they can deliver during their lifetime. Operating, recharging,
and maintenance techniques can extend or reduce total battery
life. As the batteries in this product are consumed, the amount
of useful work between charging intervals will slowly decrease
until the battery is completely worn out. Replacement of worn out
batteries, due to normal consumption, is the responsibility of the
product owner. Battery replacement may be required during the
normal product warranty period at owner’s expense.

Maintenance is at Owner’s Expense

Engine tune-up, lubrication cleaning and polishing, replacement of
fi lters, coolant, and completing Recommended Maintenance are
some of the normal services Toro products require that are at the
owner’s expense.

General Conditions

Repair by an Authorized Toro Distributor or Dealer is your sole
remedy under this warranty.

Neither The Toro Company nor Toro Warranty Company is
liable for indirect, incidental 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. Except for the Emissions warranty referenced
below, if applicable, there is no other express 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 exclusions 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.

Note regarding engine warranty:

The Emissions Control System on your Product may be covered
by a separate warranty meeting requirements established by the
U.S. Environmental Protection Agency (EPA) and/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 Engine Emission Control Warranty Statement printed in your
Operator’s Manual or contained in the engine manufacturer’s
documentation for details.
