B. Equipment storage and installation requirements. The equipment should be stored or installed in a shady, normal temperature, ventilated and dry place. C. The equipment should be unload and transfer by forklift. (See Fig.4)×Fig. 4D. SPECIFICATIONS OF CONCRETE (See Fig. 5) Specifications of concrete must be adhered to the specification as following. Failure to do so may result in lift and/or vehicle falling. 1. Concrete must be thickness 6″ minimum and without reinforcing steel bars, and must be dried completely before the installation. 2. Concrete must be in good condition and must be of test strength 3,000psi (210kg/cm²) minimum. 3. Floors must be level and no cracks.Fig. 3 Fig. 56”E. AIR SUPPLY Air pressure requirement: 0.5Mpa~0.8Mpa, Air line size 8×6 and 6×4. F. POWER SUPPLYThe electrical source must be 2HP minimum. The source cable size must be 2.5mm² and in good condition of contacting with floor.
III. STEPS OF INSTALLATION A. Location of installationCheck and insure the installation location (concrete, layout, space size etc.) is suitable for lift installation. B. Check the parts before assembly 1. Packaged lift and hydraulic power unit (See Fig. 6).

V. TEST RUN 1. Fill the reservoir with approximately 11 L Hydraulic Oil (Note: In consideration ofPower Unit’s durabilityplease use Hydraulic Oil 46#). 2. Press button UP, the Cables will be strained. Check whether the Cablesmatch the Pulley. Make sure the Cables are not across. 3. Press the Handle of release valve to lock the Cross-beam to the safety ladders, andthen adjust the platforms to be level by adjusting the nuts of Safety Ladders. 4. Adjust the cable fitting Hex nuts to make platforms and four safety locks worksynchronously. You need to run the lift up and down for several times, meanwhile do the synchronous adjustment till the four Safety Devices can lock and release at the same time. 5. Adjust the clearance between the post and the plastic slider of Cross-beam to about 2mm, and then tighten the fixing nut of slider. 6. After finishing the above adjustment, test running the lift with load. Run the lift with Platforms in low position first, make sure the Platforms can rise and lower synchronously and the Safety Device can lock and release synchronously. And then test run the lift to the top completely. If there are anything improper, repeat the above adjustment.Circuit Diagram of Hydraulic System

VI. OPERATION INSTRUCTIONSTo lift vehicle 1. Keep clean of environment near the lift; 2. Drive vehicle to the Platform and put on the brake; 3. Turn on the power and press the button UP, raise the lift to the working position;Note: make sure the vehicle is steady when the lift is raised. 4. Press the Handle of release valve to lock the lift in the safety position. Make sure theSafety device is locked at the same height.To lower vehicle 1. Be sure the clearance of around and under the lift, only leaving operator in lift area; 2. Press the button UP, the lift will be raised for 3-5 seconds, and then press the buttonof Manual-controlled air valve by hand to make sure the safety device released, press the handle of release valve by the other hand then the lift starts being lowered automatically; 3. Drive away the vehicle when the lift is lowered to the lowest position. 4. Turn off the power.VII. MAINTENANCE SCHEDULE Monthly: 1. Re-torque the anchor bolts to 150Nm; 2. Lubricate cable with lubricant; 3. Check all cable connection, bolts and pins to insure proper mounting; 4. Make a visual inspection of all hydraulic hoses/lines for possible wear or leakage; 5. Lubricate all Rollers, Safety devices with 90wt. gear oil or equivalent.Note: All anchor bolts should take full torque. If any of the bolts does not function forany reason, DO NOT use the lift until the bolt has been replaced.Every six months: 1. Make a visual inspection of all moving parts for possible wear, interference ordamage. 2. Check and adjust as necessary, equalizer tension to insure level lifting. 3. Check columns for plumbness.31
