About your equipment warranty:
We welcome warranty repair and apologize to you for being inconvenienced.Any Authorized service dealer may perform warranty
repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For
example, warranty service would not apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping,
handling, warehousing or improper installation. Similarly, the warranty is void if the manufacturing date or the serial number on the
equipment has been removed or the equipment has been altered or modified. During the warranty period, the Authorized service
dealer, at its option, will repair or replace any part that, upon examination, is found to be defective under normal use and service.This
warranty will not cover following repairs and equipment:
• Normal Wear: Outdoor power equipment, like all mechanical devices, needs periodic parts, service and replacement to perform
well.This warranty does not cover repair when normal use has exhausted the life of a part or the equipment.
• Installation and Maintenance:This warranty does not apply to equipment or parts that have been subjected to improper or
unauthorized installation or alteration and modification, misuse, negligence, accident, overloading, overspeeding, improper
maintenance, repair or storage so as, in our judgment, to adversely affect its performance and reliability.This warranty also does not
cover normal maintenance such as adjustments, fuel system cleaning and obstruction (due to chemical, dirt, carbon or lime, etc.).
• Other Exclusions: Also excluded from this warranty are wear items such as quick couplers, oil gauges, belts, o-rings, filters,
pump packing, etc., pumps which have been run without water supplied or damage or malfunctions resulting from accidents,
abuse, modifications, alterations, or improper servicing or freezing or chemical deterioration.Accessory parts such as guns,
hoses, wands and nozzles are excluded from the product warranty.This warranty excludes failures due to acts of God and other
force majeure events beyond the manufacturers control.Also excluded is used, reconditioned, and demonstration equipment;
