• Insufficient system pressure: Worn piston, shoe plate and swash plate cause internal leakage, whole machine slow & weak digging force
• Abnormal noise & vibration: Scuffed swash plate and damaged piston create metal collision noise during pump operation
• Pump body overhigh temperature: Severe friction between worn swash plate and piston leads to oil temperature surge
• Hydraulic oil leakage: Worn piston seal and pump end cover seal ring cause oil spill from pump housing
• Unstable flow output: Scuffed swash plate surface leads to fluctuating pump output and excavator jitter

• Weak swing & sliding slope: Severe wear of motor distribution plate and aging inner seal cause high-pressure internal leakage, machine cannot stably stop on slopes
• Swing jitter & abnormal noise: Broken reducer gear or damaged bearing produces metal friction sound during rotation
• Swing oil leakage: Damaged shaft oil seal leads to hydraulic oil spill from swing motor housing
• Swing stuck & overhigh temperature: Long continuous slewing operation makes whole hydraulic system overheat

• Travel deviation: Inconsistent displacement of two-side travel motors, servo valve failure or central swivel joint seal oil leakage
• Single side no travel: Broken travel reducer gear or stuck parking brake cannot release normally
• Weak travel climbing: Stuck motor displacement adjustment mechanism, low speed with insufficient torque output

• Spool stuck: Hydraulic oil impurity blocks spool clearance, heavy operation handle, poor reset and insensitive boom/arm/bucket action
• Internal & external leakage: Worn gap between valve spool and valve body causes inner leakage; aging seal rings lead to cross-action interference
• Overflow valve failure: Stuck main overflow valve or insufficient spring pressure, system no pressure or overpressure burst hydraulic pipe

• Power drop & black smoke: Clogged air filter leads to insufficient air intake, poor atomization of fuel injector and high-pressure oil pump
• Overhigh water & oil temperature: Radiator blocked by silt, deteriorated engine oil or stuck thermostat
• Difficult startup: Starter breakdown, dead battery or air entering fuel pipeline
