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  one  year  from  date  of  purchase.    In  addition  to  the  standard  one  (1)  year  warranty,  La  Marche  warrants  it’s 
magnetics and power diodes on a parts replacement basis only for nine (9) more years under normal use. 
 
Any part or parts of the equipment (except fuses, DC connectors and other wear-related items) that prove defective within 
a  one  (1)  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.  Magnetics are warranted for ten 
(10) years after date of purchase.  During the last nine (9) years of this ten (10) year warranty period, the warranty covers 
parts replacement only, and no labor or other services are provided by La Marche, nor is La Marche obligated to reimburse 
the owner or any other person for work performed.  
 
Should a piece of equipment  require major component replacement or repair during the first year of the warranty period, 
these can be handled in one of two ways: 

1. The equipment can be returned to the La Marche factory to have the inspections, 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  year.   Transportation  charges  or  duties  shall  be 
borne by purchaser. 

 
2.  If  the  purchaser  elects  not  to  return  the  equipment  to  the  factory  and  wishes  a  factory  service 

representative to make adjustments and/or repairs at the equipment location, La Marche's field service 
labor rates will apply.  A purchase order to cover the labor and transportation cost is required prior to 
the deployment of the service representative. 

 
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.
