4. Adjust the lower speed

You can adjust the lower speed of the lift if needing: then turn the throttle valve

clockwise to decrease the lower speed, or counterclockwise to increase the lower

speed.

5. Test with load

After finishing the above adjustment, test running the lift with load. Run the lift in low

position for several times first, make sure the lift can rise and lower synchronously,

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.

NOTE: It may be vibrated when lifting at start, lifting it with load for several times,

the air would be bled and the vibration would be disappeared automatically.

Clockwise to decrease the
down speed
