IMPORTANT
PRODUCT SOFTWARE DISCLAIMER
Productsoftwareof all kinds, such as brochures, drawings, technical data, operator's and workshop manuals,
parts lists and parts price lists. and other information, instructions and specifications provided from sources
other than
Westerbeke, is not within Westerbeke's control and, accordingly, is provided to Westerbeke
customers only as a courtesy and service. Westerbeke cannot be responsible forthe content of such
software, makes no warranties or representations with respect thereto, including the accuracy,
timeliness or completeness thereof, and will in no event be liable for any type of damages or injury
incurred in connection with,
or arising outof, the furnishing or use of such software.
Forexample, components
and subassemblies incorporated in Westerbeke'sproducts and supplied byothers
(such as engine blocks, fuel systems and components, transmissions, electrical components, pumps and
other products) are generally supported by their manufacturers with their own software, and Westerbeke
must depend on such software for the design of Westerbeke's own product software. Such software may
be outdated and no longeraccurate. Routine changes made byWesterbeke's suppliers, ofwhich Westerbeke
rarely has notice in advance, are frequently not reflected in the supplier's software until after such changes
take place.
Westerbeke customers should also keep in mind the time span between printings of Westerbeke product
software, and the unavoidable existence of earlier, non-current Westerbeke software editions in the field.
Additionally, most Westerbeke products include customer-requested special features that frequently do not
indude complete documentation.
In summation, product software provided with Westerbeke products. whether from Westerbeke or other
suppliers,
must not and cannot be relied upon exclusively as the definitiveauthority on therespective prod uct.
It not only makes good sense but is imperativethatappropriate representatives of Westerbeke orthe supplier
in question be consulted to determine the accuracy and currency ofthe product software being consulted
bythe customer.
