Common Challenges and Solutions
While the RD90 is a reliable machine, like any heavy-duty equipment, it is not without its challenges. Below are some of the most common issues that users may encounter and potential solutions:

1. Hydraulic System Issues: Over time, the hydraulic system can develop leaks or pressure issues, which may reduce the machine’s effectiveness. Regular maintenance, such as checking hydraulic lines for wear and ensuring proper fluid levels, can help mitigate this problem.
   • Solution: Regularly inspect and replace hydraulic hoses and filters to ensure the system remains in optimal condition. It is also essential to use the correct hydraulic fluid and ensure proper pressure settings.
     
2. Wear on the Boom: The boom and other moving parts of the RD90 are subject to significant wear and tear due to heavy use, especially in demanding applications such as pole setting.
   • Solution: Regularly lubricate all moving components, particularly the boom and rotator, to prevent rust and ensure smooth operation. Replace any worn-out components promptly to avoid breakdowns.
     
3. Electrical System Failures: As with any modern machinery, the electrical system can sometimes malfunction, particularly if there is a failure in the wiring or the control system.
   • Solution: Perform periodic checks on the electrical system to identify and fix any wiring issues early. If the control panel is malfunctioning, recalibrate or replace the components as needed.
     
4. Tire and Undercarriage Wear: The RD90’s tires and undercarriage may wear out over time, especially when used on rough or uneven terrain.
   • Solution: Regularly inspect and replace worn-out tires. Ensure the undercarriage is kept clean and free of debris to prevent further damage.
     

Safety Considerations
Safety is always a top priority when operating heavy equipment like the RD90. Below are several safety measures that operators should follow to ensure safe operation:

1. Proper Training: Operators should be properly trained to operate the RD90, including how to handle its lifting and digging functions, as well as how to follow safety protocols.
   
2. Stabilization: Before starting any work, ensure that the machine is properly stabilized, especially when working with heavy loads or at height.
   
3. Check Load Limits: Never exceed the machine’s recommended lifting capacity. Overloading the RD90 can result in equipment failure or accidents.
   
4. Personal Protective Equipment (PPE): Operators should always wear appropriate PPE, including hard hats, gloves, and safety boots, to reduce the risk of injury.
