From there, you can identify the problem and fix the issue. Basic troubleshooting procedures can include: Check the fluids. Assess the motor. Check the hydraulic cylinder pump.

Slow Operation. A reduction in machine performance is often the first indication that there is something wrong with a hydraulic system. This usually manifests itself in longer cycle times or slow operation. It is important to remember that in a hydraulic system, flow determines actuator speed and response. Therefore, a loss of speed indicates a

Nov 01, 2017 · The tightness and condition of your excavator's tracks can impact the behavior of your final drive or travel motor. If the tracks are too tight, this causes high friction which can impede the torque generated by the travel motor. If the tracks aren't too tight, then check that the track, track idlers, and track rollers are in good shape.

If the excavator is slow, it should check the maintenance of the hydraulic system on time, and whether the hydraulic oil is replaced regularly. The expired hydraulic oil will not only affect the working efficiency of the excavator, but also corrode the hydraulic wall of the excavator.
