Mincon DTH HAMMERS 

Warranty, October 2002

 

 

Mincon warrants that the Mincon DTH Hammers and spare parts therefore, manufactured by Mincon and delivered to the initial 
user to be free of defects in materials or workmanship for a period of 3 months after initial operation or 6 months from the date 
of shipment to the initial user, whichever occurs first. Mincon may elect to repair the defective part or issue full or partial credit 
towards the purchase of a new part. The extent of credit issued will be determined on a pro-rata basis bearing in mind the 
service life of the defective part against the normal service life of that part. The part will be replaced or repaired without charge 
to the initial user at the place of business of an authorized Mincon distributor during normal working hours. The user must 
present proof of purchase at the time of exercising the warranty. 
 
The warranty applies only to failures resulting from defects in the material or workmanship and does not apply to failures 
occurring as a result of abuse, misuse, corrosion, erosion, negligent repairs and normal wear and tear. Failure to follow 
recommended operating and maintenance procedures which result in component failure will not be considered for warranty. 
  
This warranty is in lieu of all other warranties, other than title, expressed or implied.

contract, negligence, warranty, indemnity or otherwise shall not exceed the purchase price of the product upon which such 
liability is based. Mincon and its distributors shall in no event be liable to any party relating to this sale for any consequential,
