These types of excavator operations can easily damage the cylinder! How to maintain it?

1. Walk before the working device is fully recovered
When the working device is not fully retracted when walking, the bucket is easy to hit the rock, and the piston rod of the cylinder will generate a large load, which will cause the internal damage of the cylinder and the opening of the pin around

2. Excavate with walking force
When hydraulic oil is mixed with water, it is easy to emulsify and deteriorate, and entering the hydraulic system will cause rusting of parts. The rust slag flows in the hydraulic system for a long time, the hydraulic pressure will be affected, and the movement of the big and small arms and the bucket will become weak.

3. The cylinder rod stretches to the limit for excavation
The hydraulic cylinder is telescopic to the end position. In this case, the working cylinder and frame will generate a large load. The impact of the bucket teeth and the impact of each shaft pin will cause the internal damage of the cylinder and affect other hydraulic components.

4. The rear part of the crawler floats for excavation work
The excavation work is carried out by using the upward force of the back of the excavator body. When the bucket is separated from the rock, the bucket, counterweight, frame, slewing ring, etc. will be heavily loaded when the car body falls, which is easy to cause damage.

5. Start the excavator without standing firm
On uneven gravel roads, if the excavator is not stopped, starting work will cause uneven force on the lower frame and cause damage to the lower frame for a long time. It is best to put some soil below to stabilize the ground, and then work again.Prevent dirt sticking to the surface of the piston rod from entering the cylinder and damaging the piston, cylinder or seal.
5. Frequently check the connections of threads, bolts, etc., and tighten them immediately if they are loose.
6. Lubricate the joints frequently to prevent rust or abnormal wear in the absence of oil.
