Tigercat M726E MULCHER SERVICE MANUAL – PDF DOWNLOAD

INTRODUCTION :

• An Operator’s manual, Service manual and a Parts catalog are made available by Tigercat to assist the
  dealer, customer and operator in becoming familiar with the features of the M726E Mulcher serial number
  726M3501 and up.
• The M726E is a mechanical mulcher intended for use in forest mastication, vegetation management and
  land reclamation operations.
• An optional multi-function hydraulic system and quick attach boom adapter allows the machine to be
  quickly and easily switched from a mulcher to a feller buncher for increased versatility.
• When equipped with a felling head the M726E can be used for harvesting trees, selective felling, thinning
  and final felling applications in plantations and natural stands.
• The operator’s manual will assist the operator with the techniques of proper and safe operation of the
  M726E Mulcher. There is also important information regarding the safe operation of the saw head. The
  service manual contains safety and servicing procedures and a preventive maintenance schedule to assist
  in repair and to ensure optimum machine performance. For manual part numbers, see the title page in
  each manual.
• 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.
• The information contained in this manual is current at time of printing. Improvements to the machine are
  on-going 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 machine serial number HIGHER than the serial number preceding the “and up”.
• Tigercat reserves the right to make changes to the machine after this manual release date that may not
  immediately appear in this manual.
