    Why SUNWARD Excavators turbocharger noise or excessive vibration?
    • J
      Jesus PorterSep 7, 2025
      If you notice excessive noise or vibration from the turbocharger in your SUNWARD Excavators, check the turbocharger lubrication piping to ensure sufficient lubrication of the bearings. Also, inspect the turbine blades for breakage by removing the exhaust pipe and air intake hose. For bearing wear, piping leakage, or improper clearance between the turbine and its case, contact your designated distributor.

    How to troubleshoot starting problems with SUNWARD Excavators engine?
    • H
      hickslaurenAug 22, 2025
      If your SUNWARD Excavators engine runs but struggles or fails to start, possible causes include: being out of fuel (add fuel), using the wrong or polluted fuel (drain and replace with proper fuel), defective wiring (check and repair the starting circuit), insufficient battery power (charge or replace the battery), a clogged air filter (clean or replace the filter), a clogged fuel filter (clean or replace the filter), internal fuel system leaks (check and repair leaks), a fuel manual pump spring up (push down and secure the hand wheel), air in the fuel system (bleed the air), or start engine malfunction (use manual pump to bleed air). If all else fails, the start motor may need replacement.

    Why displayed temperature of coolant do not reflect real temperature in SUNWARD Excavators?
    • J
      Jacqueline SmithSep 3, 2025
      If the displayed coolant temperature on your SUNWARD Excavators does not match the actual temperature, it may be due to a defective temperature sensor. For a defective temperature sensor, defective wiring circuit or defective indicator, contacting your designated distributor for assistance is recommended.

    What causes hydraulic cylinder unable to lift loads in SUNWARD SWE155F?
    • M
      Mitchell Jennings MDSep 2, 2025
      If the hydraulic cylinder of your SUNWARD Excavators is acting but can't lift loads, it could be due to main pump wear, low pressure in the main safety valve, a clogged suction filter (clean or replace it), or a leak in the pump suction pipe (check the piping). If the hydraulic cylinder is worn out and causing internal leaks, consider replacing the piston ring or contacting distributor.

    Why SUNWARD SWE155F Excavators exhaust gas is white?
    • S
      Sean TurnerAug 31, 2025
      If your SUNWARD Excavators is producing white exhaust gas, it could be due to improper fuel (drain and replace with proper fuel) or the engine temperature being too low (run the engine to warm up). For a defective thermostat or coolant leaks into the engine cylinder, contact your designated distributor.

    Why SUNWARD Excavators shows abnormal fuel indication?
    • A
      Amanda RobertsAug 30, 2025
      If your SUNWARD Excavators shows an abnormal fuel indication, the oil level sensor might be defective (check, repair, or replace it) or there could be a defective wiring circuit (check and repair it). For a defective indicator or wiring circuit issues, contacting your designated distributor for assistance is recommended.

    Why is the hydraulic oil overheating in my SUNWARD SWE155F Excavators?
    • W
      William MejiaAug 29, 2025
      If your SUNWARD Excavators hydraulic oil is overheating, ensure you are using the correct hydraulic oil and that the oil level is at the specified level. If the oil is polluted, filter it or drain and refill with proper oil. Also, check for radiator clogging (clean the radiator and front drainer) and filter clogging (clean or replace the filter). For pump suction pipe leakage, main pump wear, or safety valve improper adjustment, contact distributor.

    What to do if SUNWARD SWE155F exhaust gas is black?
    • R
      Robin JohnsonAug 28, 2025
      If your SUNWARD Excavators is producing black exhaust gas, it could be due to improper fuel (drain and replace with proper fuel) or a clogged intake system (check, clean, and replace the intercooler if necessary). For intake piping damage, intercooler clogging, unpunctual ejection oil pump, polluted ejection nozzle, or a defective engine main block/body, contact your designated distributor.

    How to improve slow hydraulic function in SUNWARD SWE155F Excavators?
    • K
      Kelly CampbellAug 27, 2025
      If the hydraulic function of your SUNWARD Excavators is slow, consider the following: Check and replenish the hydraulic oil level to the specified mark. Allow the machine to warm up until the hydraulic oil reaches around 50°. Ensure you are using the correct type of oil for the ambient temperature. Adjust the engine revs. For issues related to main pump wear, pilot oil circuit malfunction, or a blocked main suction oil pump, contact distributor.
