5）Air Bleeding within Hydraulic Circuit (for RA Die Lifter Only)● Excessive air in the hydraulic circuit will slow the reaction timeand may result in pump continuous idling.
After installing the hydraulic circuit, or if the pump run out of oil,be sure to bleed air from the nipple in the case of RA0180/0220/0280
or from the air bleed valve in the case of RA050/080.

Cautions
Cautions● Installation Notes (Cautions for Hydraulic Series)● Hydraulic Fluid List
ISO Viscosity Grade ISO-VG-32

1）Check the ﬂuid to use● Please use the appropriate ﬂuid by referring to the Hydraulic Fluid List.
● If hydraulic oil with viscosity grade higher than
ISO-VG-32 is used, action time would be longer.
● If using it at low temperature, action time will be longer because
the viscosity of hydraulic oil becomes higher.
2）Procedure before Piping● The pipeline, piping connector and ﬁxture circuits should becleaned by thorough ﬂushing.
● The dust and cutting chips in the circuit may lead to ﬂuid
leakage and malfunction.
● Our products except some valves are not equipped withprotective function to prevent dust and cutting chips going
into the hydraulic system and pipeline.
3）Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screwing direction.
● Pieces of the sealing tape can lead to air leaks and malfunction.
● In order to prevent a foreign substance from going into
the product during piping, it should be carefully cleaned.
4）Air Bleeding in the Hydraulic Circuit● If the hydraulic circuit has excessive air, the action time may
become very long.
After installing the hydraulic circuit, or if the pump run out of oil,be sure to bleed air by the following step.
① Reduce hydraulic supply pressure to less than 2MPa.
② Please loosen the cap nut of pipe ﬁtting that is closest to
clamps・RA die lifters by one full turn.
③ Wiggle the pipeline to loosen the outlet of pipeline ﬁtting.
The hydraulic ﬂuid mixed with air comes out.

GA Clamp④ Tighten the cap nut after bleeding.
⑤ It is more eﬀective to bleed air at the highest point inside
the circuit or at the end of the circuit.
5）Checking Looseness and Retightening● At the beginning of the machine installation, the bolt/nut
may be tightened lightly.
Check torque and re-tighten as required.
