Product Advantages

• Powerful & Efficient: Equipped with a 280kW low-speed high-torque turbocharged diesel engine, it provides abundant power for heavy-load operations. The intelligent adaptive hydraulic matching system optimizes the coordination between the engine and hydraulic system, increasing working efficiency by 13% and reducing fuel consumption by 5% compared with similar products, achieving energy saving and high productivity.

• Durable & Wear-Resistant: The boom, arm, and bucket are made of high-strength alloy steel and undergo integral quenching and tempering treatment, significantly improving impact resistance and wear resistance. The heavy-duty lengthened undercarriage with reinforced track chains, rollers, and idlers extends the service life to more than 12,000 working hours, adapting to long-term high-intensity mining operations.

• Intelligent & Precise: Equipped with a 10-inch touchscreen intelligent monitor, it integrates real-time data monitoring, fault alarm, and parameter adjustment functions, enabling operators to grasp the machine’s working status at any time. The load-sensing hydraulic system realizes smooth compound actions and precise micromovement control, suitable for fine operations such as foundation digging and slope trimming.

• Comfortable & Safe: The fully enclosed pressurized cab meets FOPS/ROPS safety standards, equipped with a shock-absorbing suspension seat (150° backrest adjustment), lumbar support, and automatic heating and cooling air conditioning, effectively reducing operator fatigue. 360° panoramic vision, rearview camera, and emergency stop device ensure all-around operational safety, avoiding potential risks.

• Easy Maintenance & Adaptable: Ground-level access to filters, fuel tank, and electrical components simplifies daily inspection and maintenance, saving time and labor. The three-stage fuel filtration system and large-capacity radiator adapt to poor-quality diesel and high-temperature environments, protecting core components from damage. It is also optimized for plateau adaptability, ensuring stable operation at altitudes up to 5,500 meters.

• Heavy-Duty Earthwork: Suitable for large-scale earthwork transfer, land reclamation, site leveling, and port construction in industrial parks, ports, and airport construction sites, improving construction efficiency.

• Special Environment Projects: Optimized for plateau, high-temperature, and cold areas, applicable to plateau road construction, cold-region mining, and desert area development, with strong environmental adaptability.

Operation Guidelines

1 Pre-Operation Inspection

1. Check the levels of engine oil, coolant, hydraulic oil, and fuel, and supplement them in time if insufficient to avoid equipment damage caused by lack of fluids.

2. Inspect the track chains, rollers, idlers, and sprockets for wear, looseness, or damage; adjust the track tension according to the working condition if necessary.

3. Verify the bucket teeth, cutting edges, and bucket pins for looseness, wear, or deformation; replace damaged parts in time to ensure digging efficiency and safety.

4. Check the cab safety devices (seat belt, emergency stop button), lights, horn, and rearview camera to ensure they work normally; clean the cab windows and mirrors for clear vision.

5. Inspect the hydraulic hoses and joints for oil leakage; tighten or replace them if there is leakage to prevent hydraulic system failure.

2 Starting & Operation

1. Enter the cab, fasten the seat belt, adjust the seat height and backrest angle, and adjust the rearview mirrors to ensure a clear view of the surrounding environment.

2. Insert the key, turn to the "ON" position, wait for the system self-check (about 20 seconds), and confirm that there is no fault alarm on the monitor.

3. Press the one-click start button to start the engine, idle for 3–5 minutes to warm up the engine and hydraulic system, avoiding direct heavy-load operation.

4. Select the appropriate work mode (standard, heavy, or economy) via the control panel according to the working task; operate the left joystick to control the swing of the upper body and the lifting/lowering of the boom, and the right joystick to control the expansion of the arm and the opening/closing of the bucket.

5. Use the foot pedals to control the travel direction and speed; press the brake pedal to stop when necessary. Avoid sudden acceleration, deceleration, or turning during travel to ensure stability.

6. After operation, lower the bucket to the ground, turn off the engine, pull out the key, close the cab door, and clean the machine surface.

3 Safety Notes

• Do not overload the bucket beyond its rated capacity (2.3–3.1m³) to avoid structural damage or rollover accidents.

• Do not operate on slopes steeper than 35°; avoid turning on slopes, and park the machine on level ground when stopping to prevent slipping.

• Keep a safe distance (at least 6 meters) from personnel, vehicles, and obstacles during operation; prohibit personnel from standing under the boom or bucket to avoid safety accidents.

• Stop the engine and cut off the power supply before performing maintenance, inspection, or part replacement; hang a warning sign to prevent misoperation.

• Do not operate the excavator in severe weather such as heavy rain, strong wind, heavy fog, or thunderstorm to ensure operational safety.

FAQ

Q1: What is the fuel consumption of the XE490DK under standard working conditions?

A1: Under standard mining or earthwork conditions, the fuel consumption is approximately 23–29 L/h, which may vary slightly according to the operating load, working environment, and operation habits. The economy mode can further reduce fuel consumption by 3–5%.

Q2: Can the XE490DK work normally at high altitudes and extreme temperatures?

A2: Yes. The engine is specially optimized for plateau and extreme temperature adaptability, with a supercharger and altitude compensation system, which can ensure stable power output at altitudes up to 5,500 meters. It can also operate reliably in the temperature range of -25°C to 55°C.

Q3: What is the standard warranty period of the XE490DK?

A3: The standard warranty period is 1 year or 2,000 working hours (whichever comes first). We also provide customized extended warranty services (1–3 years) according to customers’ needs to ensure worry-free use.

Q4: What types of attachments are compatible with the XE490DK?

A4: The standard configuration is a 2.3–3.1m³ heavy-duty rock bucket. Optional attachments include 3.3m³ general-purpose bucket, hydraulic breaker, grapple, ripper, and quick coupler, which can be replaced according to different working scenarios to improve versatility.

Q5: How often should routine maintenance be performed?

A5: Routine maintenance (oil change, filter replacement) should be performed every 250 working hours; minor maintenance (hydraulic system inspection, track adjustment, lubrication) every 500 working hours; major maintenance (engine overhaul, hydraulic pump inspection, undercarriage replacement) every 2,000 working hours.

Q6: What should I do if the engine fails to start?

A6: First, check whether the fuel is sufficient and the battery power is normal. If the fuel is insufficient, supplement it in time; if the battery is low, charge it or replace the battery. If the problem still exists, check the engine ignition system and fuel supply system, or contact professional maintenance personnel for troubleshooting.
