V. TEST RUN 1. Fill the reservoir with approximately 11 L Hydraulic Oil (Note: In consideration of
Power Unit’s durabilityplease use Hydraulic Oil 46#). 2. Press button UP, the Cables will be strained. Check whether the Cables
match 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, and
then 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 work
synchronously. 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.
