Any parts (excluding filters) required within the first ten years will be furnished free of charge by the Authorized Dealer from whom the power unit was originally purchased. In addition, all SilentMaster units are guaranteed for life against defects in materials and workmanship. If an Authorized Dealer is not nearby, M.D. Manufacturing, Inc. will honor and perform required warranty services. The end user must return the unit to the factory freight pre-paid. This warranty does not apply to applications outside of North America, commercial applications, misuse, abuse, acts of God, operating without the filters, or units tampered with by unauthorized personnel.
