Notes : 1. If hydraulic oil with viscosity grade higher than listed on Hydraulic Fluid List (ISO-VG-32 or equivalnt), action time will be longer.
2. If using it at low temperature action time will be longer because of high viscosity of hydraulic oil.
3. Be sure to set an automatic drain air filter when air contains a large amount of moisture, or air supplying pipe is located at the end.
4. When setting a pressure gauge to hydraulic circuit, install a damper or use an oil filled (glycerin) pressure gauge
in order to prevent damage caused by pressure surging.
5. Provide enough space at the bottom of the unit in consideration of hydraulic oil change.
(Tank cleaning and suction strainer tightening become easier.)

Cautions
Cautions● Installation Notes (Cautions for Hydraulic Series)
1) Check the Usable Fluid● Please use the appropriate ﬂuid by referring to the Hydraulic Fluid List.
● If viscosity grade of hydraulic oil is higher than ISO-VG-32,
action time becomes longer.
● If using it at low temperature, action time will be longer because
the viscosity of hydraulic oil becomes higher.
2) Procedure before Piping● Pipelines, piping connectors and others should be cleaned bythorough ﬂushing.
● Dust and cutting chips in the circuit may lead to ﬂuid leakage
and malfunction.
● Our products except some valves are not equipped with protectivefunction that prevents contamination.
3) Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screw direction.
● Pieces of the sealing tape can lead to ﬂuid leakage and malfunction.
● Please implement piping construction in a clear environment toprevent anything getting in products.
4) Air Bleeding of the Hydraulic Circuit● If the hydraulic circuit has excessive air, the action time may become
very long. If air enters the circuit after connecting the hydraulic port
or under the condition of no air in the oil tank, please performthe following steps.
① Reduce hydraulic pressure to less than 2MPa.
② Loosen the cap nut of pipe ﬁtting closest to the clamp by one full turn.
③ Shake the pipeline to loosen the outlet of pipe ﬁtting.
Hydraulic ﬂuid mixed with air comes out.

GA Clamp④ Tighten the cap nut after bleeding.
⑤ It is more eﬀective to release 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 and nut may
be tightened lightly. Check the looseness and re-tighten as required.

safety devices are in place. Shut oﬀ the pressure and power source,2) Regularly clean the area around the product.
● If it is used when the surface is contaminated with dirt, it may
lead to packing seal damage, malfunctioning and ﬂuid leakage.

and make sure no pressure exists in the hydraulic and air circuits.
③ After stopping the product, do not remove until the temperaturedrops.
④ Make sure there is no abnormality in the bolts and respective parts
before restarting the machine or equipment.
3) Do not touch a clamp (cylinder) while it is working.
Otherwise, your hands may be injured.
3) If disconnecting by couplers, air bleeding should be carried out
on a regular basis to avoid air mixed in the circuit.
4) Regularly tighten bolts, pipe line, mounting bolt, nut, snap ring,cylinder and others to ensure proper use.
5) Make sure the hydraulic ﬂuid has not deteriorated.
4) Do not disassemble or modify.
● If the product is taken apart or modiﬁed, the warranty will be
voided even within the warranty period.

6) Make sure there is a smooth action without an irregular noise.
● Especially when it is restarted after left unused for a long period,
make sure it can be operated correctly.
