Warranty
The Craftsman Blower model 316.794970 comes with a two-year limited warranty from the date of purchase. This warranty covers any defects in material or workmanship, provided the blower is used and maintained according to the operator's manual. Sears will repair these defects free of charge. However, the warranty does not cover the spark plug, air filter, and vacuum bag as these are expendable parts that can wear out from normal use in less than two years.
If the blower is used for commercial or rental purposes, the warranty applies for only 30 days from the date of purchase. To claim the warranty, you need to return the blower to the nearest Sears store or Sears Parts & Repair Center in the United States.
The product also has a California/EPA Emission Control Warranty for two years. This covers parts such as the carburetor or fuel-injection system, the ignition system, and catalytic converter, as well as hoses, belts, connectors, and other emission-related assemblies. If any emission-related part on your engine is defective, the part will be repaired or replaced by Sears at no cost to you, including diagnosis, parts, and labor.
To claim this warranty, you should present your small off-road engine to a Sears authorized service center as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. For the nearest location, please contact Sears at 1-800-4-MY-HOME®.
Please note, warranty coverage may be denied if your small off-road engine or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications. Also, the use of add-on or modified parts can be grounds for disallowing a warranty claim.
