& nbsp; The manual scissor lift channel has the characteristics of strong mobility, easy operation and protection, and is widely used in daily life. Many friends may have seen the manual scissor lift channel. Below, let's introduce how to maintain the hydraulic system of the manual scissor lift channel.

  & nbsp; Clean hydraulic oil is the lifeblood of hydraulic systems. There are many fine components in hydraulic systems, some with damping holes, some with gaps, etc. If solid impurities invade, it will cause fine parts to be pulled, stuck, and blocked in the oil passage, endangering the safe operation of the hydraulic system. The ways in which general solid impurities invade hydraulic systems include: unclean hydraulic oil; The fuel is not clean and tidy; Careless refueling, repair, and maintenance; Hydraulic component chip removal, etc. It can avoid solid impurities invading the system from the following aspects.

  & nbsp; It is necessary to filter and add hydraulic oil, and the filling material should be firm and clean. The filter at the fuel tank filling port cannot be removed in order to improve refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.

  & nbsp; When disassembling the hydraulic oil tank filling cover, filter cover, inspection hole, hydraulic oil pipe and other parts to form a system oil passage that is exposed, avoid dust. The disassembled parts must be completely cleaned before opening. When removing the hydraulic oil tank filling cap, first remove the soil around the tank cap, loosen the tank cap, and remove any debris remaining at the joint (do not rinse with water to prevent water from entering the tank). Only after cleaning can the tank cap be opened.
