Precautions
1. The flow rate characteristics show the representative values of the product itself.
They may change depending on piping, circuit and pressure conditions, etc. The flow rate characteristics
and the number of needle rotations vary due to the range of the specifications of the product.
2. The needle has a retaining mechanism, so it will not turn further when it reaches the rotation stop
position.
Turning the needle too far may cause damage.
3. Do not tighten the handle with tools such as nippers.
This can result in breakage due to idle turning.
4. Do not over tighten the lock nut.
It is possible to tighten the standard lock nut (hexagon) manually. When tightening further with tools,
tighten by approximately 15° to 30°. Over tightening may cause breakage.
5. When Vacuum break flow adjusting needle screwdriver operation type needle is selected as
option (K), make sure the lock nut is not loose to prevent the nut from coming off due to vibration.
