All ROSSFELDER Corporation Vibrocoring units are warranted for a period of one year (12 months) from date of purchase for the original owner. We will repair at our facility, without charge for parts or labor, any defects due to faulty materials or workmanship. This warranty does not apply to accessories or damage caused by improper usage, electrical damage caused by improper current supplies or voltage loss due to long power cable lengths. This warranty also does not cover leaks or water damage to vibrator motor or electrical controls. A complete vacuum inspection of the vibrohead and O-ring inspection of all connections prior to each day of operation is recommended.

To obtain warranty service the customer must receive a return authorization from Rossfelder Corporation and the unit must be shipped PREPAID. Rossfelder Corporation will not accept COLLECT freight. Unit must be packaged in a wood crate with forklift skids and insured. All warranty work will be returned freight collect.

While great effort has been made to provide guidelines and energy outputs for each model, ROSSFELDER Corporation cannot warrant its vibrocoring units to penetrate a specific water saturated substrate to a particular depth. Customers are cautioned that core-depth-penetration is greatly affected by water content, grain size and shape, type of material, depositional environment, cementation, etc. Therefore the suitability of a unit for a specific application must be determined by the customer and cannot be warranted by ROSSFELDER Corporation.
