Engine and Emission Control SystemMaintenance:
- Proper inspection, maintenance and repair is essential to keeping engine and machine systems properly operating.
- This includes proper inspection and maintenance of the machine’s emission control system.
- This could include machine and engine components, such as an EGR (Exhaust Gas Recirculation) system, fuel system, turbocharger, electrical system, air intake system and/or cooling system. As a heavy-duty off-road diesel engine owner, you are responsible for performing required maintenance.
- The required maintenance procedures are outlined in this Operation & Maintenance Manual, or Shop Manual.
- Do not remove, alter, or render inoperative, any emission control system.
Machine Capacity:
- Do not exceed machine capacity by modifying machine or using unapproved attachments.
- Exceeding machine capacity can adversely affect machine performance characteristics such as: stability, system certifications such as brakes and steering, the Roll-over Protective Structure (ROPS) and can result in death or serious injury.
- Contact your DOOSAN distributor for further information.
Attachments:
- These and other attachments are approved for use on this machine.
- Do not use unapproved attachments.
- Attachments not manufactured by DOOSAN may not be approved. See your DOOSAN distributor for information about approved attachments and attachment manuals.
