Note 7 – Warranty

The Company provides a warranty for most of its products. Warranties are for periods ranging from ninety days to one year, and cover parts and labor for non-maintenance repairs at our locations. Operator abuse, improper use, alteration, damage resulting from accident, or failure to follow manufacturer’s directions are excluded from warranty coverage.

Warranty expense is accrued at the time of sale based on historical claims experience. Warranty reserves are also accrued for special rework campaigns for known major product modifications. The Company also offers extended warranty service contracts for select products when the factory warranty period expires.
