V. TEST RUN
1. Fill the reservoir with approximately 12L Hydraulic Oil (Note: In consideration of Power
Unit’s durability，please use Hydraulic Oil 46#
）；
2. Press button till the cables are strained. Check the cables and confirm they are
in the proper pulley position. Make sure the cables are not across
.
3. Press button Down1 ，the cross beam will be locked to the safety ladders ; and then
adjust the platforms to be level by adjusting the nuts of safety Ladder. Tighten the nuts
above and under the safety ladder top plate after leveling.
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 column and the slide block of cross-beam, Do not
tighten the bolts of the slide block, let the sliding block can be turned smoothly after
installing the bolts.
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.
