PC210-10MO Excavator 708-8F-31320 / 708-8F-31570 Excavator Travel Device

Strict 100% Factory Inspection: Each complete assembly undergoes hydraulic pressure test, high/low speed function test and leak detection before shipment.

1. The lubricating oil maintenance cycle of the rotary motor is 1000 hours. In daily operation, observe the amount of rotary lubricating oil from the dipstick. Check for abnormal loss of lubricating oil and inspect whether lubricating oil leaks into the large ring gear cavity through the sealing ring.
2. The general rotation gear inspection and lubricating oil replacement cycle is every 2000 hours or one year. The butter filling amount for a 20-ton machine is about 36 liters (two barrels). Periodically open the boom base and the square cover on the front of the frame to check the ring gear and lubrication conditions. For maintenance or if water is found, go to the X overhead cavity at the bottom of the excavator and open the cover to release the water.
3. There is a common misunderstanding among customers about the maintenance of slewing bearings. They believe that the lubricating oil of the slewing bearing is the same as the lubrication cycle of the big and small arms, and they need to be lubricated every day. In fact, such actions have the opposite effect. If the lubrication cycle is too short, there will be too much lubricating oil in the bearing, which will burst the dust ring and leak out.
