The die clamping thickness of GN clamp should be h±0.5mm.
If using dies other than prescribed, clamps cannot conductlocking action normally and it leads to accident or injury.

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 inthe circuit may lead to ﬂuid leakage and malfunction.
(There is no ﬁlter provided with this product for prevention ofcontaminants in the hydraulic piping or hydraulic system.)3）Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screwing direction.
When piping, be careful that contaminants such as sealing tape

and cause an accident.

● The hydraulic machine and air compressor should be handled
and maintained by qualiﬁed personnel.
3）Do not handle or remove the machine unless the safety protocols
are ensured.
① The machine and equipment can only be inspected or preparedwhen it is conﬁrmed that the preventive devices are in place.
② Before the machine is removed, make sure that the above-mentioned
safety measures are in place. Shut oﬀ the air of hydraulic source
and make sure no pressure exists in the hydraulic circuit.
③ After stopping the machine, do not remove until the temperaturecools down.
④ Make sure there is no abnormality in the bolts and respective
parts before restarting the machine or equipment.
4）Do not touch clamps while they are working.
● Otherwise, your hands may be injured.

5）When changing the width of the die, make sure to check theallowable protrusion amount.
● If using it with beyond allowable protrusion amount, excessive
force is applied to the clamp which deforms or damages theclamp resulting in falling oﬀ of the die and accident or injury.
Please refer to "Notes for Design (6)” on P.067 for the allowable
protrusion amount.
6）Please hold the main body of the clamp when moving or removing it.
● If pulling on hydraulic hose or air tube, the clamp will fall oﬀ
leading to accident or injury. Also, rivet part of the hose will beloosened leading to ﬂuid leakage.

※ Please refer to P.177 for common caution.

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.
