YEAR FROM THE DATE OF PURCHASE, BUT IN NO EVENT TO EXCEED (18) EIGHTEEN MONTHS FROM THE DATE
OF SHIPMENT FROM THE FACTORY.
Jackson MSC agrees under this warranty to repair or replace , at its discretion, any original part which fails under normal use due to faulty
material or workmanship during the warranty period, providing the equipment has been unaltered, and has been properly installed, maintained and operated in accordance with the applicable factory instruction manual furnished with the machine and the failure is reported to
the authorized service agency within the warranty period. This includes the use of factory specified genuine replacement parts, purchased

The labor to repair or replace such failed part will be paid by Jackson MSC, within the continental United States, Hawaii and Canada, during
the warranty period provided a Jackson MSC authorized service agency, or those having prior authorization from the factory, performs the
service. Any repair work by persons other than a Jackson MSC authorized service agency is the sole responsibility of the customer. Labor

these components is not covered by Jackson MSC.
This warranty is void if failure is a direct result from shipping, handling, fire, water, accident, misuse, acts of god, attempted repair by unauthorized persons, improper installation, if serial number has been removed or altered, or if unit is used for purpose other than it was originally intended.
TRAVEL LIMITATIONS
Jackson MSC limits warranty travel time to (2) two hours and mileage to (100) one hundred miles. Jackson MSC will not pay for travel time
and mileage that exceeds this, or any fees such as those for air or boat travel without prior authorization.

THIS IS THE ENTIRE AND ONLY WARRANTY OF JACKSON MSC. JACKSON’S LIABILITY ON ANY CLAIM OF ANY KIND, INCLUDING
NEGLIGENCE, WITH RESPECT TO THE GOODS OR SERVICES COVERED HEREUNDER, SHALL IN NO CASE EXCEED THE PRICE
OF THE GOODS OR SERVICES OR PART THEREOF WHICH GIVES RISE TO THE CLAIM.

FORTH HEREIN, OR THAT EXTEND BEYOND THE DURATION HEREOF. UNDER NO CIRCUMSTANCES WILL JACKSON MSC BE
