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.
