Frequently Asked Questions
How to choose the right excavator model according to construction needs?
Consider working conditions (earthwork, mining, etc.), operating range, and excavation depth. Small excavators (≤13 tons) suit narrow spaces; large excavators (≥30 tons) are for heavy mining projects.
What preparations are required before starting a new device for the first time?
Check fuel, lubricating oil, and coolant levels; confirm hydraulic pipelines are tight; check tire/track pressure; and conduct a no-load test run.
How to reactivate equipment that has been parked for a long time?
Check for impurities in the fuel system, replace engine oil and filters, check battery power, and perform a low-load operation test.
How long is the regular maintenance cycle of the equipment?
Daily cleaning/lubrication is required. First-level maintenance occurs every 250 hours, second-level every 1000 hours, and comprehensive overhaul every 4000 hours.
How to deal with oil leakage in the hydraulic system?
Stop the machine immediately to avoid fire. Temporarily seal the leak point with special plugs and contact professional maintenance personnel.
Will technical support still be provided after the device is out of warranty?
Yes, lifetime technical consulting services are available for out-of-warranty equipment, including paid repairs and maintenance packages.
