This liability of Welch-Ilmvac under this warranty is limited to servicing, adjusting, repairing,

impaired performance or rendering it inoperative. No other warranties are expressed or 
implied. The method of executing this warranty: servicing, adjusting, repairing, or replacing, 
shall be at the discretion of Welch-Ilmvac. Vacuum pumps that have been operated within a

3. The product in our judgment is defective through no action or fault of the user. 

 

If the product has become defective through misuse, abuse, alteration, or ingestion of foreign
