Operational misuse, neglect, accidents, unauthorized repairs or
attempted repairs of the engine or its components by anyone other
than an authorized MTD service provider.
GDO0-100163 Rev.B
Repairs or adjustments to correct starting difficulties dueto any
of the following: failure to follow proper maintenance procedures
-- rotary mower blade striking an object -- contaminants in the
fuel system --improper fuel or fuel/oil mixture (consult your
Operator's Manual if in doubt) -- failure to drain the fuel system
prior to any period of non-use over three months.
.
Any starting problem which results from the use of inappropriate
fuels, lubricants, or additives.
e
Special conditions or circumstances that normally require more
than two pulls to start, specifically: 1) First start-up following your
initial purchase, 2) first time starts after extended period(s) of
non-use over one month or seasonal storage, 3) cool temperature
starts such as those found in early spring and late autumn, and 4)
difficult starting that results from the operator's failure to follow
the proper starting procedures identified in the Operator's Manual.
If you are having difficulty starting your unit, please check the
Operator's Manual to ensure that you are using the correct starting
procedures. This can save an unnecessary visit to a Service
Dealer.
Owner Responsibilities
You must maintain your mower (including its engine) by following the
maintenance procedures and starting instructions described in the
Operator's Manual. Such routine maintenance, whether performed by
a dealer or by you, is at your expense. In addition, please retain your
proof of purchase and service receipts as these may be required to
validate a claim.
General Conditions
An authorized MTD service provider using approved replacement
parts must perform all repairs covered by the EZ Start Promise.
Repair by an MTD authorized service dealer is your sole remedy
under this warranty. MTD is not liable for indirect, incidental, or
consequential damages in connection with the use of the products
covered by these warranties, 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.
Some states do not allow exclusions of incidental or consequential
damages, or limitations on how long an implied warranty lasts, so
certain exclusions and limitations may not apply to you.
