Ownership & Support
Shipping & Receiving
22. What should I check when receiving a new mini excavator?
Check hydraulic oil, engine oil, and fuel levels. Start the machine and test all functions. Inspect hydraulic hoses for leaks. Verify all accessories are included. Always use the dipstick as the primary oil level reference.
23. What must I do after daily operation?
Turn off the main power switch to prevent battery drain. Apply grease to all pins and pivot points every day.
24. How should I store a mini excavator for a long time?
Disconnect the battery and recharge it periodically. Store the machine in a dry, sheltered place.
Maintenance & Fluids
25. What engine oil and hydraulic oil should I use?
Use CF-4 15W-40 engine oil for diesel engines. Use L-HM46 anti-wear hydraulic oil. Always check the dipstick, not just the specified volume.
26. How often should I change the hydraulic oil?
For a new machine, change hydraulic oil and return filter at 500 hours. After that, change every 1500 hours.
27. How often should I replace air and fuel filters?
Clean the air filter every 50–100 hours (more often in dusty conditions). Replace the fuel filter every 500 hours.
Starting & Electrical
28. Mini excavator won't start – what should I check first?
Check the main power switch, battery voltage, and fuses. A resting battery voltage above 12.3V is normal; below 11.5V means the battery is low.
29. Engine cranks but won't fire – what's the problem?
Air in the fuel line is the most common cause. Open the injector screw, pump the hand primer until fuel flows without bubbles, then tighten and restart.
30. What do the warning lights on my mini excavator mean?
Oil pressure light: low oil pressure – stop the engine immediately. Air filter light: clogged filter – clean or replace. Battery light: charging system issue – check battery, wiring, and alternator.
Hydraulic System
31. Why does my mini excavator move unevenly?
Swap the left and right travel motor hoses and test again. If the deviation direction changes, the problem is the multi-way valve. If it stays the same, the problem is the travel motor.
32. The joystick has no pilot action – why?
Check the pilot safety switch under the left joystick. If the switch is OK, clean the pilot solenoid valve – the valve core is likely stuck.
33. Can I adjust the main relief valve pressure myself?
No. Do not adjust the main relief valve yourself. Improper adjustment can cause hose burst or hydraulic pump damage. Only professional service personnel should perform this operation.
Engine Overheating
34. What causes a mini excavator to overheat?
Common causes include a clogged radiator, faulty thermostat, loose or broken fan belt, low coolant, and leaking hoses.
35. What should I do if the engine overheats?
Stop the machine immediately and let it cool down. Do not open the radiator cap while hot. To check the thermostat: if the upper hose is hot and the lower hose is cold, the thermostat may be stuck closed.
Undercarriage & Tracks
36. Why does my mini excavator keep throwing tracks?
Common reasons: low track tension from a leaking tension cylinder, worn or deformed idler/sprocket, stretched track, or sharp turns.
37. How should I adjust track tension?
Adjust to the proper tension – not too tight. Too tight accelerates track wear; too loose causes derailment.
Warranty & After-Sales
38. What is not covered by warranty?
Damage from human impact or structural deformation is not covered by warranty.
39. What information is needed for a warranty claim?
Provide the engine number and clear photos of the fault. This helps our after-sales team register and process your claim quickly.
