1.view the boom cylinder's leakage. 1. lihat kebocoran silinder boom. Rises in the most simple way is to arm and see if their freedom significantly reduced. Kenaikan dengan cara yang paling sederhana adalah mempersenjatai dan melihat apakah kebebasan mereka berkurang secara signifikan. If whereabouts apparently opened oil tank view, seal if it is worn it should be replaced; Jika keberadaannya tampaknya membuka tampilan tangki minyak, segel jika sudah dipakai itu harus diganti;

Pertama-tama bersihkan katup pengaman, lihat spool aus, seperti aus dan harus diganti. Safety valve installation if there is no change, then view the operation valve wear, its clearance limit usually 0.06mm wear Stern should be replaced; Pemasangan katup pengaman jika tidak ada perubahan, kemudian lihat keausan katup operasi, batas bebasnya biasanya 0.06mm aus Stern harus diganti;
3.measure the pressure of hydraulic pumps. 3. mengukur tekanan pompa hidrolik. If the pressure is too low, adjust pressure adjustment, then clarify severe wear of hydraulic pump. Jika tekanannya terlalu rendah, sesuaikan penyesuaian tekanan, kemudian jelaskan keausan pompa hidrolik yang parah.
