reasons.\u003cbr\u003e– Even if speed is satisfactory, in case power is weak, refer to the troubleshooting for faulty main relief valve (F-1\/S-1).\u003cbr\u003e– If actuator speed of only front attachment is slow, the pilot system may be faulty (A-1) or the circuit after the pilot valve may be faulty (F-2).\u003cbr\u003e– If actuator speed of only steering is slow, the circuit after the steering pilot valve may be faulty (S-3).\u003cbr\u003e– Refer to SYSTEM \/ Hydraulic System.\u003cbr\u003eProcedure\u003cbr\u003eInspection
