  maintenance schedule and servicing procedures to ensure optimum performance.
• Section 1 contains safety information that must be followed. As well, throughout the rest of the manual WARNING
  and CAUTION notices are displayed where necessary, drawing attention to possible hazards when performing certain
  procedures.
• The operator of this equipment must be made aware of the fact that; The safety of the people on the ground i.e.,
  workers or bystanders is the responsibility of the harvesting head and machine operator.
• Only trained personnel should be allowed to operate or work on the harvesting head and machine.
• The information contained in this manual is current at time of printing. Improvements to the harvesting head are ongoing
  and may not be covered, therefore in these cases contact your Tigercat dealer for the appropriate information.
• The phrase “and up” appearing in this manual after the serial number implies that the related information is current for
  any harvesting head serial number HIGHER than the serial number preceding the “and up”.
• Tigercat reserves the right to make changes to the harvesting head after this manual release date that may not
  immediately appear in this manual.
