Discard exhausted hydraulic oil, tighten the oil filter adapter pulled out after cleared, cleaned with compressed air, and then back into the tank and connected piping. (Replace with new oil, do not continue to use the old oil. Otherwise, hydraulic lift system will accelerate the wear and tear of moving parts).
2. Remove and disassemble lowering valve lift, plunger blowing with compressed air, and then into re-placement.
3. Check all hydraulic pipes and fittings. Pipeline can not have broken, can not have loose joints, it is necessary to tighten all fittings.

Year-end maintenance
Oil and oil level 1. The hydraulic oil. Lift the whole rises when this position should be higher than the bottom of hydraulic ground 40 to 50 mm. Such as found in hydraulic oil darkens, sticky or gritty and other foreign matter, should be replaced (32 # hydraulic oil).
2. The parts are filling some of the oil, to extend the lift bearing life. Check the hydraulic lift wheel, the intermediate shaft and bearings, cylinder pin and bearing, boom hinge shaft and bearings for wear.
3. between any part of the hydraulic system, it is necessary first of all relief, in order to avoid pressure oil spray, lift table Passed decline.
4. The relief valve shall not be adjusted. Hydraulic lift system for each element is designated to work under pressure. After any adjustment relief valve may cause abnormal operation of the hydraulic system.
5. In the following test lift work platform, it is necessary Diaozhu, supporting the work platform lifts, lift Passed prevent decline.
6. To prevent electric shock or incorrect connections, non-professional staff are not free removable appliances.
