Safe Operation is Operator’s Responsibility:
Only trained and authorized personnel should operate and maintain the machine.
Follow all safety rules, regulations and instructions when operating or performing maintenance on machine.
• Do not operate machine if you are under the influence of drugs or alcohol. An operator who is taking prescription drugs must get medical advice to determine if he or she can safely operate a machine.
• When working with other personnel on a work site, be sure that all personnel know nature of work and understand all hand signals that are to be used.
• Be sure that all guards and shields are installed in their proper location. Have guards and shields repaired or replaced immediately if damaged.
• Be sure that you understand the use and maintenance of all safety features such as safety lever and seat belt. Use them properly. • Never remove, modify or disable any safety features. Always keep them in good operating condition.
• Always check for and know the location of underground and overhead utility lines before excavating.
• Failure to use and maintain safety features according to instructions in this manual, Safety Manual and Shop Manual can result in death or serious injury.
Know Your Machine:
- Know how to operate your machine.
- Know the purpose of all controls, gauges, signals, indicators and monitor displays. Know the rated load capacity, speed range, braking and steering characteristics, turning radius and operating clearances.
- Keep in mind that rain, snow, ice, loose gravel, soft ground, slopes etc., can change operating capabilities of your machine
Proper Work Tools and Attachments:
- Only use work tools and attachments that are recommended by DOOSAN for use on DOOSAN machines.
- When installing and using optional attachments, read instruction manual for attachment, and general information related to attachments in this manual.
- Because DOOSAN cannot anticipate, identify or test all attachments that owners may want to install on their machines, contact DOOSAN for written authorization and approval of attachments, and their compatibility with optional kits.
- Attachments and attachment control systems that are compatible with the machine are required for safe and reliable machine operation. Do not exceed maximum operating weight (machine weight plus attachment) that is listed on ROPS certification plate. Make sure that all guards and shields are in place on machine and on work tool.
- Depending on type or combination of work equipment, there is a potential that work equipment could interfere with the cabin or other parts of machine.
- Before using unfamiliar work equipment, check if there is any potential of interference, and operate with caution.
- While you are performing any maintenance, testing, or adjustments to attachments, stay clear of the following areas: cutting edges, pinch points, and crushing surfaces. Never use attachment as a work platform or manlift. Contact your DOOSAN distributor about auxiliary hydraulic kits for attachments installation.
- If you are in doubt about compatibility of a particular attachment with a machine, consult your DOOSAN distributor.
