How to use for the energy saving lifter
Adjustment
1) Open the inlet valve of the pilot system(Sp) and main
system(Sm).
2) Set the lifting speed of the cylinder by REG(1). The pressure

pressure which lift the cylinder).
P
= Pw + Pu > Pw

To reduce the internal pressure of the tank, reduce the
pressure with the discharge valve(E) of the tank before
resetting with REG(1).
3) Cylinder upper chamber pressure(P
and REG(2) is the pressure which overcomes compressed
pressure(Pu + ΔP) in the lower chamber to the tank chamber
at the lower end of the stroke.

4) In order to release air from the device for maintenance, close
the inlet valve for the main system (Sm) to release the air in
the tank with exhaust valve (E), then discharge air in the
cylinder upper chamber from VEX
from the pilot. This prevents lurching of the cylinder.
