the applicability of warranty, a call to USM is recommended before work proceeds.

shop.  No labor credit will be issued for work done in the field (i.e., at the machine site) except 

by specific factory authorization.   Travel time to and from machine will not be warranted.  Ac-

tual warranty compensation will be based on USM flat rate manual.

USM liability is specifically limited to the replacement of components for its products if a 

warrantable defect is discovered. Collateral damage to property or personal injury is ex-

clusively the responsibility of the owner and or operator since USM has no control over the
