How to choose the right excavator model according to construction needs?
Consider the working conditions (earthwork, mining, etc.), operating range, excavation depth, and load. Small excavators (≤13 tons) suit narrow spaces; large excavators (≥30 tons) are best for mining and heavy earthwork.
What preparations are required before starting a new device for the first time?
Check fuel, lubricating oil, and coolant levels; confirm hydraulic pipeline and circuit connections; check tire/track pressure and wear; and complete equipment initialization parameter settings.
How to reactivate equipment that has been parked for a long time?
Check for impurities in fuel, replace oil and filters, check battery power, manually crank the engine to ensure no jamming, and perform a low-load test run while observing instrument data.
What is the recommended regular maintenance cycle?
Perform daily cleaning/lubrication; first-level maintenance every 250 hours (filter/hydraulic oil); second-level every 1000 hours (key components); and third-level comprehensive overhaul every 4000 hours.
How should I deal with oil leakage in the hydraulic system?
Stop the machine immediately to avoid high-temperature fire risks. Use temporary seals for the leakage point to prevent impurities from entering 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. We provide technical support, maintenance solutions, and accessory matching for all models.
