  • Under normal use conditions, the coolant change interval for the 743 XL is set at 1,200 hours or 24 months, whichever comes first.
  • A coolant level check is specified at every 50 hours of operation under normal use, placing routine inspection on a far shorter cycle than the full drain-and-fill service.
