  M724D Mulcher. In addition, the operator’s manual contains important information regarding the safe
  operation of both a mulching head and a saw head, as the M724D Mulcher is convertible for use as a
  Feller Buncher. The service manual contains safety and servicing procedures and a preventive
  maintenance schedule to ensure optimum machine performance.
• Section 1 in both the operator’s manual and the service manual contains safety information that must be
  followed. As well, throughout the rest of the manuals, WARNING and CAUTION notices are displayed
  where necessary, drawing attention to possible hazards when performing certain procedures.
• Only trained personnel should be allowed to operate or work on the machine.
