Doosan DX350LC-5 Excavator Operation & Maintenance Manual 950106-01000NA-1 – PDF DOWNLOAD

• This Operation & Maintenance Manual was written to give owner or operator instructions on safe operation and maintenance of DOOSAN equipment.
• READ AND UNDERSTAND THIS OPERATION AND MAINTENANCE MANUAL BEFORE OPERATING YOUR DOOSAN EQUIPMENT.
• Keep this manual in the cabin so it is always available. If it is lost, order another one from your DOOSAN distributor.
• If there are any questions, contact your DOOSAN distributor. This manual may illustrate options and accessories not installed on your equipment.
• Any modification made without written authorization or approval from DOOSAN can create a safety hazard. Always replace parts with genuine DOOSAN parts or DOOSAN authorized replacement parts.

• The machine is intended to be used under normal conditions for applications described in this manual.
• If it is used for other purposes, or in potentially hazardous environments, special precautions must be followed and the machine must be equipped for such use.
• Examples include, but are not limited to, are: falling object guards, work lights, etc. Do not engage in prohibited uses as described in this manual.
• Contact your DOOSAN distributor for further information.

• 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.

• 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.
