Seller will not assume expense or liability for repairs made outside the factory 
by other than Seller's employees without Seller's written consent. 
 
SELLER  IS  NOT  RESPONSIBLE  FOR  DAMAGE  TO  ANY  ASSOCIATED 
EQUIPMENT,  NOR  WILL  SELLER  BE  HELD  LIABLE  FOR  INCIDENTAL, 
CONSEQUENTIAL,  OR  OTHER  DAMAGES.  THIS  WARRANTY  IS  IN  LIEU
