Step 7: Fill with hydraulic oil.
ONLY CLEAN AND FRESH OIL ONLY .Lift must be fully lowered before changing or adding hydraulic oil.
Pour 18 liters anti-abrasion hydraulic oil into the oil tank. The level of oil shall reach the tippets volume mark of the tank.
Run the lift for several cycles and add more oil until the lifting platform can reach its maximum height.
Note
：
As running speed of the lift is mainly decided by the viscosity of the hydraulic oil, we suggest using NO.46 hydraulic oil when
average temperature of the location is above 18 degree Celsius and using NO.32 hydraulic oil when temperature is below 18 degree
Celsius.
Change the oil 6 months after initial use and change once per year thereafter.
Step 8: Levelling.
Check the connection of the hydraulic and electrical system before levelling operation
Review operation instructions and get familiar with lift controls by running the lift through a few cycles before levelling operation.
Attention: Level the platforms before connecting max height limit switch because if not, platforms may not rise to the highest position.
The operator needs to know clear which levelling valve controls which platform. This could be judged by the way that the oil hose was
connected or by trial raising or lowering.
Open one of the levelling valves and push the UP button to supplement oil to the oil hose connected. Turn off the valve to stop adding oil.
In normal working condition, both levelling valves shall be turned off. In the case both valves are open, two platforms of the lift can still rise
but will not move upwards synchronously.
A. Both valves open
B. Both valves closed

D.
One valve open, the other closed: levelling condition
A.1.
Turn on both levelling valves and push the UP button to have both platforms raised to the highest positions. Repeat this step for two
or three times. (Take care that this step could be time consuming, because there’s air in the cylinders and no load on the platforms.)
A.2.
Turn off both levelling valves as per drawing B. Push the UP button to see if both platforms rise synchronously. (Normally, till now the
platforms may not rise synchronously.)
A.3.
If not work synchronously, one platform may rise faster than the other. Users should first judge which leveling valve controls which
platform and then turn on the valve that controls the slower-rising platform to supplement oil into its oil hose. Push the UP button to
make both platforms rise to the same height. (The other valve here must be closed.)
A.4.
Turn off both levelling valves. Push DOWN I button to have both platforms lowered to the lowest position.
A.5.
In case they do not lower synchronously, turn on the valve that controls the slower-lowering platform and push DWON I button to have
