MANUFACTURER’S WARRANTY 

 
 
All  La  Marche  Manufacturing  Co.  equipment  has  been  thoroughly  tested  and  found  to  be  in  proper  operating 
condition upon shipment from the factory and is warranted to be free from any defect in workmanship and material 
that may develop within three (3) years from date of purchase. 
 
Any part or parts of the equipment (except fuses, d.c. connectors and other wear-related items) that prove defective 
within a three (3) year period shall be replaced without charge providing such defect, in our opinion, is due to faulty 
material or workmanship and not caused by tampering, abuse, misapplication or improper installation. 
 
Should  a  piece  of  equipment  require  repair  during  the  warranty  period,  the  equipment  can  be  returned  to  the  La 
Marche factory to have the inspection, parts replacements and testing performed by factory personnel.  Should it be 
necessary to return  a piece of equipment or parts to the factory, the  customer or sales representative  must obtain 
authorization  from  the  factory.    If  upon  inspection  at  the  factory,  the  defect  was  due  to  faulty  material  or 
workmanship, all repairs will be made at no cost to the customer during the first three years.  Transportation charges 
or duties shall be borne by purchaser. 
 
In accepting delivery of the  equipment, the  purchaser assumes full responsibility for proper installation, installation 
adjustments  and  service  arrangements.    Should  minor  adjustments  be  required,  the  local  La  Marche  sales 
representative should be contacted to provide this service only. 
 
All  sales  are  final.    Only  standard  LaMarche  units  will  be  considered  for  return.    A  25%  restocking  fee  is  charged 
when return is factory authorized.  Special units are not returnable. 
 
In  no  event  shall  La  Marche  Manufacturing  Co.  have  any  liability  for  consequential  damages,  or  loss,  damage  or 
expense directly or indirectly arising from the use of the products, or any inability to use them either separately or in 
combination with other equipment or materials, or from any other cause.  In addition, any alterations of equipment 
made by anyone other than La Marche Manufacturing Co. renders this warranty null and void. 
 
La Marche Manufacturing Co. reserves the right to make revisions in current production of equipment, and assumes 
no obligation to incorporate these revisions in earlier models. 

 

The failure of La Marche Manufacturing Co. to object to provisions contained in customers' purchase orders or other 
communications shall not be deemed a waiver of the terms or conditions hereof, nor acceptance of such provisions. 
 
The above warranty is exclusive, supersedes and is in lieu of all other warranties, expressed or implied, including any 
implied  warranty of  merchantability or  fitness.   No person, agent or  dealer is authorized  to  give any warranties on 
behalf  of  the  Manufacturer,  nor  to  assume  for  the  Manufacturer  any  other  liability  in  connection  with  any  of  its 
products unless made in writing and signed by an official of the manufacturer.
