all service calls and/or parts needs relating to a warranty issue.  Any repeat service calls must also be authorized as well.  This allows 
for proper diagnosis and action.  Helmer will not be responsible for charges incurred for service calls made by third parties prior to 

authorization from Helmer.  Helmer retains the right to replace any product in lieu of servicing it in the field.
