The output power of the hydraulic pump is insufficient to determine whether the small excavator is decelerated due to the continuity of the hydraulic pump, test the relevant pressure in the maintenance diagnostic system. You can also determine whether pilot pressure is insufficient, spool valve pressure is insufficient, flow is insufficient, or speed is reduced.Ģ. Suppose the speed of the excavator is slow. You should carefully check the hydraulic system to see if hydraulic oil is changed regularly. Long-term use of hydraulic oil will not only affect the performance of small excavators but also corrode the hydraulic walls of excavators. Also, make sure that the return filter and hydraulic oil circuit are not blocked.ģ. The engine power of the excavator may be very low. This will reduce the output of the excavator, destroy the excavator's brakes, and reduce the overall speed of the excavator. High quality Hyundai Excavator Bucket Teeth Pins R210 R220-7 R225-9 Excavator Teeth Pin from China, Chinas leading E330 komatsu replacement parts Product. If the engine power is low, you need to ensure that all cylinders run smoothly. Next, carefully check the smoke from the engine.
