Installation, Operation and Parts Manual
Step5: Leveling
Attention: Level the platforms before connecting height limit switch because if not, platforms can not rise to the highest position.
Before leveling, make sure the oil hoses are correctly connected. Otherwise, oil cylinders may not work synchronously or could be
damaged. In addition, operators need to know clear which leveling valve controls which platform. This could be judged by the way that
the oil hose was connected or by trial raising or lowering.
Manual leveling
Open one of the leveling valves and press the UP button to supplement oil to the oil hose connected. Close the valve to stop adding oil.
In normal working condition, both leveling valves are closed. If both valves are open, two platforms of the
hoist
can still rise but will not
move upwards synchronously.
