When climbing a slope, the machine lacks power and becomes very slow.
Swing motion becomes noticeably weak when the boom and arm are fully extended.
Overall, the machine feels underpowered in general operation.
The pump delivery pressure (No.14), as shown on the monitor, does not exceed around 210 kg/cm² (≈20.6 MPa).
Even while climbing a slope under heavy load, the pressure never goes above 210 kg/cm².
Is this 210 kg/cm² pump pressure (monitor value) too low for proper travel and swing performance?
If anyone has experienced similar symptoms or can offer suggestions for possible causes, I’d really appreciate your input.
