1. It must be mounted with recommended torque. Because of the structure of the metal seal,
if mounting torque is insufficient, the flow control valve may not be able to adjust the flow rate.
2. Do not attach a used BZT to other clamps.
Flow control will not be made because the bottom depth difference of G thread makes metal seal insufficient.

1. It is not recommended to use BZT for TC040□ / TC048□ / TL□040□ / TL□060□, since they have small cylinder capacity and it isdifficult to adjust the speed.
2. In case of controlling TMA / TLA, both lock side and release side should be meter-in circuit.
If meter-out circuit is used, abnormal high pressure is created, which causes oil leakage and damage.

Notes
1. Please read "Notes on Hydraulic Cylinder Speed Control Unit" for proper hydraulic circuit design.
Improper circuit design may lead to malfunctions and damages. (Refer to P.1356)
2. It is dangerous to release the air under high pressure. It must be done under lower pressure.
(For reference : the minimum operating range of the product within the circuit.)
3. When the cylinder capacity is small, the speed of flow may not be controlled properly. (Recommended Cylinder Capacity：3cm3 or more)

Cautions● Installation Notes (For Hydraulic Series)● Hydraulic Fluid List

1）Check the Usable Fluid● Please use the appropriate ﬂuid by referring to the Hydraulic Fluid List.

ISO Viscosity Grade ISO-VG-32

Maker
Showa Shell Sekiyu

2）Procedure before Piping● The pipeline, piping connector and ﬁxture circuits should be cleanedby thorough ﬂushing.
● The dust and cutting chips in the circuit may lead to ﬂuid leakage
and malfunction.
● There is no ﬁlter provided with Kosmekʼs product except for a partof valves which prevents foreign materials and contaminants fromgetting into the circuit.
3）Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screw direction.
● Pieces of the sealing tape can lead to oil 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.

④ 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.
(Set an air bleeding valve at the highest point inside 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.

【Meter-out Circuit】(Except LKE/TMA/TLA)② In the case of meter-out circuit, the inner circuit pressure may
increase during the cylinder action because of the ﬂuid supply.
The increase of the inner circuit pressure can be prevented by
reducing the supplied ﬂuid beforehand via the ﬂow control valve.
Especially when using sequence valve or pressure switches forclamping detection. If the back pressure is more than the set
