Check the appearance of the machine: Inspect the boom, arm, bucket and crawler track for damage, deformation or loose bolts; check the cab for damage and the door and window seals for tightness.
Check the fluid levels: Check the fuel, engine oil, hydraulic oil, coolant and brake fluid levels, and add them in time if they are insufficient; check for oil leaks in the hydraulic system, engine and fuel system.
Check the electrical system: Inspect the battery for loose connections and sufficient power; check the lights (headlights, taillights, turn signals), horn and instrument panel for normal operation.
Check the attachments: If equipped with a bucket, breaker or other attachments, check the connection bolts for tightness and the hydraulic hoses for damage or leaks.
Start the engine: Turn on the power switch, start the engine, let it idle for 3-5 minutes, and check the engine sound, oil pressure, water temperature and other parameters for normal operation; check the hydraulic system for abnormal noise.
Starting the machine: After completing the pre-operation check, sit in the cab, fasten the safety belt, adjust the seat and steering wheel to a comfortable position, turn on the power switch, start the engine, and wait for the engine to run stably.
Moving the machine: Push the left joystick forward to move the machine forward, pull it back to move backward; push the joystick to the left or right to turn left or right. When moving on uneven terrain, slow down to avoid tipping.
Digging operation: Push the right joystick forward to lower the bucket, pull it back to lift the bucket; push the joystick to the left to curl the bucket, push it to the right to unload the bucket. During digging, keep the bucket level, avoid excessive digging to prevent damage to the machine.
Loading operation: After digging, lift the bucket to the appropriate height, move the machine to the transport vehicle, align the bucket with the vehicle compartment, push the right joystick to the right to unload the materials; after unloading, return the bucket to the original position.
Stopping the machine: Stop the machine on a flat and stable ground, lower the bucket to the ground, turn off the engine, turn off the power switch, and pull the parking brake. After stopping, clean the machine and check for any abnormalities.
Operators must be trained and certified before operating the machine; do not allow untrained personnel to operate the machine.
Do not operate the machine under the influence of alcohol, drugs or fatigue; keep a clear mind during operation.
When operating near personnel, obstacles or buildings, slow down and sound the horn to remind; do not allow personnel to stand under the boom, arm or bucket.
Do not operate the machine on steep slopes (slope angle should not exceed 30 degrees); avoid sudden acceleration, deceleration or turning to prevent tipping.
When the machine is working, do not touch the hot parts (engine, exhaust pipe) to avoid burns; do not open the fuel tank cap when the engine is running to avoid fuel splashing and ignition.
If the machine fails during operation, stop the machine immediately, turn off the engine, and perform maintenance after troubleshooting; do not continue to operate the faulty machine.
Q: What should I do if the engine fails to start?
A: First, check the battery power and connection status; if the battery is dead, charge it or replace it. Then check the fuel level and fuel filter; if the fuel is insufficient, add fuel; if the fuel filter is blocked, replace it. If the problem still exists, check the engine ignition system and fuel injection system, or contact professional maintenance personnel.
Q: Why does the hydraulic system have insufficient pressure?
A: Possible reasons include insufficient hydraulic oil, blocked hydraulic filter, damaged hydraulic pump, or leakage in the hydraulic pipeline. First, check the hydraulic oil level and add it if necessary; then check the hydraulic filter and replace it if blocked; check the hydraulic pipeline for leaks and repair them; if the hydraulic pump is damaged, replace it.
Q: How to reduce fuel consumption during operation?
A: Operate the machine smoothly, avoid sudden acceleration and deceleration; adjust the engine speed according to the operation load, do not keep the engine at high speed for a long time; regularly maintain the engine and hydraulic system to ensure their normal operation; choose high-quality fuel that meets the standard.
Q: What is the maintenance cycle of the XE390G excavator?
A: The regular maintenance cycle is as follows: 50 hours (first maintenance) - check and tighten bolts, replace engine oil and filter; 250 hours - replace hydraulic oil filter and fuel filter; 500 hours - replace hydraulic oil and coolant; 1000 hours - inspect the boom, arm and crawler track, replace worn parts if necessary. Specific maintenance items can refer to the product maintenance manual.
Q: Can the XE390G be equipped with different attachments?
A: Yes, the XE390G can be equipped with a variety of attachments, including standard bucket, heavy-duty bucket, breaker, grapple, ripper, etc. Different attachments can be replaced according to different operation needs, which greatly expands the application scope of the equipment. It is recommended to use original attachments to ensure compatibility and safety.
Q: What should I do if the machine tips during operation?
A: Immediately stop the machine, turn off the engine, and do not move the joystick randomly. Ensure the safety of the operator first, then call professional rescue personnel to handle it; do not try to lift the machine by yourself to avoid secondary damage.
Q: Why does the bucket have serious wear?
A: Possible reasons include using the bucket to dig hard materials (such as rocks, concrete) for a long time, the bucket material does not meet the requirements, or the operation method is incorrect. It is recommended to choose the appropriate bucket according to the operation material; avoid using the bucket to hit hard objects; regularly check the bucket wear and replace the wear-resistant parts in time.
Q: How to store the machine when it is not used for a long time?
A: Park the machine on a flat and dry ground, lower the bucket to the ground, turn off the engine, and turn off the power switch. Drain the fuel, engine oil, hydraulic oil and coolant if necessary; clean the machine, apply anti-rust oil to the metal parts; cover the machine with a waterproof cover to prevent dust and rain erosion. Check the machine regularly during storage to ensure it is in good condition.
