LIMITED WARRANTY
Subject to the conditions set forth below, for one year after the original purchase date of the

of a defect in materials or workmanship.

Lavry Engineering may exchange new or rebuilt parts for defective parts. Please call the factory

This warranty is extended only to an original purchaser of the product from Lavry Engineering,

purchase will be required before warranty service is provided. This warranty only covers failures
due to defects in materials or workmanship and does not cover damages which occur in shipment
or failures resulting from accident, misuse, line power surges, mishandling, maintenance,
alterations and modifications of the product, or service by an unauthorized service center or
personnel. Lavry Engineering reserves the right to deny warranty service to products that have
been used in rental, service bureau, or similar businesses.

This limited warranty gives you specific legal rights. You may have others which vary from
state/jurisdiction to state/jurisdiction.
