Fault phenomenon: after the oil pump is started, there is no oil or the amount of oil is insufficient
Reason 1: Insufficient or no oil in the fuel tank
Remedy 1: Refuel to the oil level gauge line
Reason 2: The filter is clogged
Remedy 2: Clean or replace the filter
Reason 3: The fuel tank is airtight
Remedy 3: Check if the fuel tank vent is blocked
Reason 4: The oil suction pipe joint is loose and the air intake
Remedy 4: Tighten the pipe joint
Fault phenomenon: insufficient pressure of hydraulic system
Reason 1: Relief (pressure regulating) valve spring fatigue
Remedy 1: Adjust its limit nut or replace the spring
Reason 2: The overflow (pressure regulating) valve seat cone valve is damaged or stuck
Troubleshooting method 2: Remove the pressure reducing valve sleeve to check and troubleshoot
Reason 3: Oil leakage from hydraulic components or pipelines
Elimination method 3: Check components and pipeline maintenance
Reason 4: There is air in the system
Remedy 4: Exhaust, and check the cause of the intake and eliminate it
Fault phenomenon: the force of the coupling is not enough to cause it to slip
Reason: Excessive wear or fragmentation of the friction plate, failure or rupture of the compression spring
Remedy: replace the friction plate or replace the spring
Fault phenomenon: excessive wear of the heating elastic ring of the coupling
Reason: poor coaxiality when the power machine and the clutch are assembled
Elimination method: improve assembly coaxiality
Fault phenomenon: hydraulic system oil temperature is too high
Reason 1: Too little oil in the fuel tank
Remedy 1: Refuel to the oil level gauge line
Reason 2: The oil pump is damaged
Remedy 2: Repair or replace the oil pump
Reason 3: The oil pump work selection is unreasonable
Elimination method 3: Reasonable selection of working pump
Reason 4: The oil pump is working under too high pressure
Elimination method 4: Select working pressure according to the recommendation of the manual
