Maintenance of stationary scissor lift
1. Safety Instructions
a. Non-electrical professionals are not allowed to disassemble and assemble the electrical components of the scissor lift platform at will to prevent electric shock or misconnection.
b. When it is necessary to enter the bottom of the working platform of the lifting platform for maintenance, the working platform of the lifting platform must be suspended to prevent the sudden drop of the lifting platform and cause casualties.
c. Non-professionals are not allowed to adjust the relief valve arbitrarily. Every component in the hydraulic system works under specified pressure. Any adjustment of the relief valve may cause abnormal operation of the hydraulic system. There will be unnecessary damage to people, machines and objects.
d. Before disassembling any part of the hydraulic system, the pressure must be released first to prevent the pressure oil from spraying out and the workbench suddenly sliding down.
2. Year-end maintenance
a. Check all hydraulic piping and fittings. Pipes must not be damaged, joints must not be loose, and all joints must be tightened.
b. Remove and disassemble the down valve, blow off the plunger with compressed air, then install it and reinstall it.
c. Discard the hydraulic oil, tighten the joint to take out the oil filter, clean it with compressed air, put it back into the oil tank, and connect the pipeline.
Replace with new oil, do not continue to use old oil. Otherwise the moving parts in the system will wear out at an accelerated rate.
