Cautions

Cautions (JTC/JTD)
1. Do not connect or disconnect the auto coupler under pressure. (Refer to the following Circuit Reference.)
2. Release the air from the circuit before use.
3. Do not connect the coupler when contaminants are adhered on each connecting surface.
When there are cutting chips or coolant, install a cover, or remove all contaminants with air blow.
4. If load is applied to the actuator on the fixture side while disconnected, it will be pressurized and fluid may leak from the coupler end.
5. Exceeding allowable offset leads to damage on internal parts. It is recommended to install a guide pin.
6. When using connection limit stopper(s) or multiple couplers (more than three of them), make sure it becomes

the connection setting dimension when connected.

Connection Limit Stopper (Seating Suface)7. When pressing up to the connection limit, the force should be higher than the reaction force and lower than 1.0kN.
8. For mounting and removing the coupler, use the mounting jig (ZZJ0040) or equivalent.
9. When using with the pallet clamp (VS/WVS), it is recommended to use the auto coupler model JVC/JVD.
(When using JTC/JTD with the pallet clamp: If a pallet might be lifted up by the spring reaction force when setting,the connection setting dimension needs to be reconsidered. Please contact us.)

③ After stopping the product, do not remove until the temperaturedrops.
④ Make sure there is no trouble/issue 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) Regularly clean the reference surfaces (taper reference surfaceand seating surface) of locating products (SWT/SWQ/SWP/VRA/
VRC/VX/VXE/VXF/WVS/WVG/VWH/VWM/VWK).
● Locating products (except VRA/VRC/VX/VXE/VXF and SWR without

● Continuous use with dirt on components will lead to locating failure,ﬂuid leakage and malfunction.

4) Regularly tighten pipe, mounting bolt, nut, snap ring, cylinderand others to ensure proper use.
5) Make sure the hydraulic ﬂuid has not deteriorated.
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.
7) The products should be stored in the cool and dark place
without direct sunshine or moisture.
