sale relating to the original purchase order should be consulted. Damage caused by wear and tear, inad-
equate maintenance, corrosion, or by the effects of chemical processes are excluded from this warranty

In the event of warranty claim, the defective goods should be sent (freight paid) to the service depart-
ment of the relevant sales organization for repair or replacement (at Yokogawa discretion). The following
