3-2. Piping
Caution
(1) Preparation before piping.
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove
cutting chips, cutting oil and other debris from inside the pipe.
(2) Wrapping of sealant tape.
When connecting pipes and fittings, etc., be certain that cutting chips from the pipe threads and sealing
material do not get inside the piping. Also, when sealant tape is used, leave 1 thread ridge exposed at end
of the pipe / fitting.

3-4. Cautions for mounting
Warning
(1) Ensure sufficient space for maintenance work.
When installing the product, allow access for maintenance.
(2) Tighten threads to the proper tightening torque.
When installing the product, follow the specified torque.
(3) Do not perform additional machining to the product.
Additional machining to the product can result in insufficient strength and cause damage to the product.
This can lead to possible human injury and damage to the surrounding equipment.
(4) Do not enlarge the fixed throttle by modifying the pipe connectors.
If the hole diameter is enlarged, the product’s piston speed will increase, causing the shock force to
increase and damage to the product. As a result, it could pose a hazard to humans and damage the
machinery and equipment.
