Excavator use tips overview

Identify any obstacles or uneven terrain to ensure safe operation. While working, check the front and rear of the tracks to avoid tipping or collision. Avoid facing the final drive directly during excavation, as this can damage the motor or hydraulic hoses. Keep both tracks fully in contact with the ground to maintain stability and prevent accidents. 2. **Effective Excavation Technique** For optimal digging force, position the bucket cylinder and the arm cylinder at a 90-degree angle relative to each other. Maintain a 30-degree angle between the bucket tooth and the ground for minimal resistance. When using the stick, keep its angle between 45 degrees forward and 30 degrees backward. Combine the movement of the boom and the stick to increase efficiency and reduce workload. 3. **Excavating Rocks** Avoid using the bucket directly on hard rocks, as this can cause significant damage. Adjust the machine’s position based on the rock’s natural cracks to allow smooth digging. Insert the teeth into the cracks and use the combined force of the stick and bucket to break and remove the material carefully. If the rock is not broken, use a hammer or chisel first before proceeding with the bucket. 4. **Slope Leveling** When finishing a slope, ensure the machine is on stable ground to prevent shaking. Coordinate the movements of the boom and stick, and control their speed to achieve a smooth and even surface. This helps improve the quality of the work and reduces time spent on adjustments. 5. **Loading Operations** Keep the machine body in a horizontal and stable position to ensure accurate unloading. Maintain a proper distance from the truck to avoid collisions during turns. Prefer left turns for better visibility and efficiency. Control the rotation angle to minimize turning time. Position the truck lower than the excavator to shorten the boom lift time and improve visibility. Place smaller materials first, followed by larger rocks, to reduce impact on the truck bed. 6. **Working in Soft or Wet Conditions** In soft soil or wet areas, understand the soil density and limit the bucket’s excavation depth to prevent slippage or sinking. When working in water, ensure the water level does not exceed the center of the carrier roller. Water entering the rotating bearing can cause poor lubrication, while water in the engine may damage fan blades or short-circuit electrical components. 7. **Lifting Operations** Only use a hydraulic excavator for lifting tasks. Confirm the lifting area is clear and use strong hooks and steel cables. Employ a micro-operation mode and move slowly to maintain balance. Ensure the sling length is appropriate—too long can cause instability. Adjust the bucket position to prevent the cable from slipping. Keep personnel away from the load to avoid injury from unexpected movements.
