How to maintain the chain in accessories? The chain plays a role of traction and transmission on the excavator, and it is also a common original accessory. For long service life without deformation and rust, such accessories need proper daily maintenance.

For original chains, no special daily maintenance is required, but lubrication is necessary. It is easy to lubricate the rollers and sprockets, but difficult to lubricate the chain pins and bushings. Therefore, the lubricating oil must have good permeability; otherwise, it cannot effectively lubricate the pins and bushings. It must also have good adhesion. During operation, lubricating oil may be thrown off at high speed or drip down at low speed due to gravity. Therefore, the lubricant for original accessories must have strong adhesion and firmly adhere to the surface.
