More Safe Operation with

New KOSMEK Hole Clamp
Cap Structure Available in Any Condition※ SFA/SFC1000 does not have the cap.

Clearance between
the Cap and the Gripper

Minimum clearance between the cap
and the gripper prevents cutting chips
from entering inside the hole clamp.

Small clearance leads to effective
purging. Even with a little air flow
it prevents coolant from entering
inside the hole clamp.

Gripper

Workpiece

Cap

Workpiece does not have contact
with gripper.
It makes loading-unloading smooth.

Notes :
※1. The clamping part is an adjusting structure and the clamping operation is done by locating the workpiece hole. The numerical value inthe table shows the amount of tolerance value of single clamp. Please consider the center distance accuracy of each clamping installation
part and each workpiece hole when used with another location clamp / location cylinder, or when using more than two of these products.
※2. Workpiece lifting stroke and workpiece lifting force are functions only for lifting option.
※3. Clamping force cannot be calculated from the cylinder inner diameter and the rod diameter. Please refer to the clamping force curve.

4) Use air piping with outer diameter φ6 (inner diameter φ4) orlarger for air blow.
● In order to conduct an eﬀective air blow, it is recommended to use
air piping with outer diameter φ6 (inner diameter φ4) or larger.
5) Restarting at Hydraulic Pressure OFF (Neutral) State.
It is recommended to supply hydraulic pressure from the release sideat the ﬁrst hydraulic supply after installing a clamp, or when restartingat both lock and release hydraulic pressure OFF (neutral) state.
When supplying hydraulic pressure from the lock side, a small amountof oil may leak from the clamping part for a moment, but this is not afunctional problem.

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.

Refer to P.75 for speed adjustment of LKE.
For TMA and TLA, if meter-out circuit is used, abnormal highpressure is created, which causes oil leakage and damage.
【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
pressure then the system will not work as it is designed to.

2) Regularly clean the area around the piston rod and plunger.
● If it is used when the surface is contaminated with dirt, it may leadto packing seal damage, malfunctioning and ﬂuid leakage.

③ After stopping the product, do not remove until the temperaturedrops.
④ Make sure there is no abnormality in the bolts and respective parts

● Continuous use with contaminant on components will lead tolocating accuracy failure, malfunction and ﬂuid leakage.

4) If disconnecting by couplers, air bleeding should be carried out
on a regular basis to avoid air mixed in the circuit.
5) Regularly tighten nut, bolt, pin, cylinder, pipe line and others toensure proper use.
6) Make sure the hydraulic ﬂuid has not deteriorated.
7) 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.
