FAQ

1. Equipment selection and configuration
Q: How to choose the right excavator model according to construction needs?
A: When choosing an excavator, you need to consider the type of working conditions (earthwork, mining, municipal engineering, etc.), operating range, excavation depth and load requirements. For example, small excavators (≤13 tons) are suitable for narrow spaces or shallow earthwork operations; large excavators (≥30 tons) are suitable for mining and heavy earthwork projects. It is recommended to contact our technical consultant and provide specific construction scenarios, and we will provide a selection plan.

2. Operation and Use
Q1: What preparations are required before starting a new device for the first time?
A: 1. Check whether the fuel, lubricating oil and coolant are sufficient and meet the specifications;
2. Confirm that the hydraulic pipeline and circuit connections are not loose;
3.Check the tire/track pressure and wear;
4.Complete the equipment initialization parameter settings (such as instrument panel calibration). It is recommended to conduct a no-load test run after the first start.

Q2: How to reactivate equipment that has been parked for a long time?
A: First check whether there are impurities or moisture in the fuel system, replace the engine oil and filter; check the battery power, charge or replace if necessary; manually crank the engine to confirm that there is no jamming; gradually start the equipment, perform a low-load operation test, and observe whether the instrument data is normal.

3. Maintenance and care
Q1: How long is the regular maintenance cycle of the equipment?
A: Daily maintenance (cleaning, lubrication, tightening) needs to be performed every day; first-level maintenance (replacing the filter element, checking the hydraulic oil) is recommended every 250 hours or once a month; second-level maintenance (deep inspection of key components) is every 1000 hours or once a quarter; third-level maintenance (comprehensive disassembly and overhaul) is every 4000 hours or once a year. For details, please refer to the equipment "Maintenance Manual".

Q2: How to deal with oil leakage in the hydraulic system?
A: Stop the machine immediately to avoid fire caused by high temperature; use special plugs or sealants to temporarily seal the leakage point to prevent impurities from entering; if you cannot handle it yourself, contact professional maintenance personnel and do not operate with faults.

4. Accessories and after-sales service
Q1: How to buy original accessories?
A: You can place an order online through the official website accessories mall, or contact a local dealer; provide the device model and factory number, and we will accurately match the accessories. You can enjoy a 12-month warranty when purchasing original accessories.

Q2: Will technical support still be provided after the device is out of warranty?
A: Lifetime technical consulting services are available for out-of-warranty equipment. We provide paid repairs, maintenance packages and accessories discounts. Join the VIP customer program to enjoy priority service and discount rights.

5.Safety and Compliance
Q: How to operate the equipment safely in extreme weather?
A: In hot weather, the equipment heat dissipation inspection should be strengthened to avoid long-term overload operation; in rainy and snowy weather, the snow/mud on the tracks should be cleared and anti-skid measures should be added; in strong winds exceeding the equipment safety standards, the equipment should be fixed and the operation should be stopped.
