Limited Warranty 

 

Introduction

  This warranty policy and procedures guide is prepared for the use and guidance of authorized Lorenz 

Manufacturing Company dealers and distributors in handling matters of warranty and service of all products sold by Lorenz 

Manufacturing Company of South Dakota. 
 

Product Warranty

  Lorenz Manufacturing Company warrants each new Lorenz product to be free from defects in material 

and workmanship.  This warranty is for normal service life of the product, machine or parts involved and not to exceed six (6) 

consecutive months from the date of delivery of the Lorenz product to the purchaser-user. 
 

Under no circumstances does the warranty cover any merchandise or component parts which, in the opinion of the company, 
have been subject to negligent use, misuse, alteration, accident, or if repairs have been made with parts other than those 

manufactured and obtainable from Lorenz Manufacturing Company. 
 

Our obligation under this warranty is limited to repairing or replacing free of charge to the original purchaser-user any part 
that in our judgment shows evidence of defect or improper workmanship, provided the part is returned to Lorenz 

manufacturing Company within thirty (30) days of the failure.  Parts must be returned through the selling dealer and 

distributor, transportation charges prepaid. 
 

This warranty shall not be interpreted to render Lorenz Manufacturing Company liable for injury or damages of any kind, 
direct, consequential, contingent to persons or property.  Furthermore, this warranty does not extend to loss of crops, losses 

caused by harvest delays or any expense or loss for labor, supplies, rent machinery or for any other reason. 
 

There are no warranties, either express or implied, of merchantability or fitness for particular purpose intended or fitness for 
any other reason. 

 
This warranty cannot guarantee that existing conditions beyond the control of Lorenz Manufacturing Company will not affect 

our ability to obtain materials or to manufacture necessary replacement parts. 
 

Lorenz Manufacturing Company reserves the right to make design changes, improve design or change specifications at any 
time, without any contingent obligation to purchasers of machines and parts previously sold. 

 

No one is authorized to alter, modify or change this warranty in any way. 
 

Warranty Period

  This warranty is effective for only the normal service life of component parts of the product, not to 

exceed six (6) consecutive calendar months.  Warranty period begins on the day the product is delivered to the original 

purchaser-user (confirmed by copies of sales invoice signed and returned to Lorenz Manufacturing Company). 
 

Wear

  Under no circumstances are component parts warranted against wear that is not related to defective materials or 

workmanship.  Wear is a normal thing to any moving part.  Use varies greatly from customer to customer within the same 

product line making it impossible to consider any guarantee against wear and tear. 
 

Replacement Parts Warranty

  All replacement parts have a maximum ninety (90) day warranty.  No parts warranty will be 

honored where parts are not returned within thirty (30) days of replacement.  Copy of sales invoice on which parts were 

purchased must accompany claim. 
 

Warranted Parts Replacement

  Parts replaced under warranty are guaranteed only until the expiration of the original six-

month warranty of the product.  Under no circumstances or conditions by alteration or replacement of parts is the warranty 

extended beyond its original termination date.  Copy of sales invoice on which unit was purchased must accompany claim. 

 

Procedure in Handling Warranty Claim 

1.  Confirm the product is within the warranty period.  Check sales slip, warranty registration copies, etc. to confirm. 
2.  Carefully examine the parts claimed under warranty.  Check all circumstances and facts related to the failure.  The 

warranty is not designed to recondition warn out parts. 
3.  If the part has obviously failed because of defective material or poor workmanship, it will be replaced under warranty.  If 

the part is simply worn out with no evidence of defect, advise the customer immediately and deny the warranty claim. 
4.  The dealer must complete the warranty claim giving all pertinent information requested.  See procedure for returned 

merchandise. 
5.  No consideration will be given warranty claims where dealers fail to follow procedures noted in 1 through 4 above. 

6.  After the service department approves the warranty claim, the dealer will receive credit or replacement as applicable for 
the parts warranted.  If the claim is rejected, the dealer will receive proper notification from the service department why claim 

was not approved. 
7.  Warranty claims not submitted within thirty (30) days of the date of failure will not be accepted.
