        Frequently Asked Questions
        Lifts have been tested before shipment and commissioning, the technical indicators meet the design requirements , use only power , hydraulic, electrical systems without adjustment . Note that the lift is in use , must be placed on a solid flat surface , while working to prevent tipping . Press the "up" or "down" button to lift the table . If the table does not move, should immediately be shut down for inspection. Found that work pressure is too high or electric lift sounds abnormal, should be immediately shut down checks , in order to avoid mechanical devastated ; regular monthly checks axle pin working condition, if found axle pin , screw loose , must be locked to prevent the axle pin off causing the accident. Hydraulic oil should be kept clean , replaced once every six months ; during maintenance and cleaning lifts, be sure to hold up the safety strut .
        Lift maintenance
        A monthly maintenance
        When the lift maintenance personnel into the inner workings of the lift , the lift must Diaozhu lifts prevent a sudden drop caused casualties.
        A. Check the wheel, intermediate shaft and bearing ; cylinder pin and bearing ; boom hinge shaft and bearing lubrication and wear ;
        B. The above components add oil. Extend bearing life.
        C. Check the hydraulic oil and the oil level. Rose to the highest hydraulic lift oil tank bottom should be higher than 40-50 mm. Hydraulic oil gets dark , sticky oil , or oil when there is gravel and other foreign matter , should be replaced hydraulic oil. Hydraulic lift 32 # hydraulic oil system applications .
        2 year-end maintenance
        A. Check the hydraulic and pipe joints . Should immediately replace the damaged pipeline ; When joints are loose tighten fittings.
        B. Remove and disassemble drop valve spool blowing with compressed air from the newly installed .
        C. The hydraulic oil tank exhausted all open tank , remove the oil filter , washed back into the tank , according to in-situ installation. The new tank filled with new oil.

        Can not afford to lift up or rise weak
        1 pressure relief valve to adjust the pressure regulator does not meet the requirements to the required value
        2 inside the fuel tank vent check or replace the fuel tank assembly
        3 valve clamping or check or replace the vent valve assembly
        4 . The oil level is too low , add a little oil into the oil filter clogged oil, oil filter cleaning
        5 check or replace the faulty pump for pump
        Ripper can not afford to lift or rise weak
        1 pressure relief valve to adjust the pressure regulator does not meet the requirements to the required value
        2 fuel tank vent see above item 2.3.4.5 of Remedy
        3 or the vent valve clamping
        4 . The oil level is too low , into the oil filter clogging
        5 for faulty pump
        6 one-way check valve leak check valve and valve seat wear damage , whether the one-way valve spring fatigue , deformation, etc.
        Operating lever heavy
        1 operating lever mechanism faulty inspection, adjustment , replacement of defective parts ; cleaning valves ; Check the hydraulic oil cleanliness
        2 control valve spool clamping ( manufacturing, installation , dirt problem )
        Defective torque converter and compensation systems , such as torque converter weakness, power shift failure, high oil temperature , etc.
        A torque converter weakness
        Less ( 1 ) hydraulic oil
        ( 2 ) improper regulator
        ( 3 ) Check the torque converter oil backpressure insufficient quality ( if misused hydraulic transmission oil ) , dosage, check the torque regulator , back pressure valve and its set pressure value
        2 powershift failure
        ( 1 ) . Faster return valves, valves , power shift valve , valve appears stuck, internal leakage
        ( 2 ) Oil pollution check valve stuck causes and accordingly excluded or replace hydraulic oil filter
        ( 3 ) . Cooler temperature rise is too large to check whether faulty , check the hydraulic oil quality brand
