Note! For LPU-S do not operate the directional slide of hand pump to release pressure. The oil
inside actuator will flow back to hand pump, but oil will not flow from hand pump to tank
line of actuator. Thus oil will be emptied out of LPU if LPU-S is closed by operating the
directional slide of hand pump.
