Click IDLE (Air bubbles entered at the time of syringe
mounting will be purged through the port 4 (BACK FLUSH).
(10) Secure the plunger setscrews with your hand to fasten the

NOTES: 1. While the inside of the syringe is dry, avoid moving
the plunger unless absolutely necessary. Otherwise,
the plunger tip will wear out abnormally.
2. If the syringe is not filled with liquid, it lacks lubricity.
Therefore, the syringe may not move normally.
3. Securely screw the syringe manually to the syringe
mount. Incomplete screwing may deteriorate joint
sealing and cause poor performance.
4. During replacement of the syringe, do not move the
hook forcedly. Otherwise, a syringe operation error will
take place (to be reset by clicking IDLE).
5. When fitting the plunger groove of syringe into the hook,
make sure the plunger setscrew is secured. If it is loose,
the instrument will not provide the original performance.
6. When filling the syringe with a liquid, take care not to
forcedly press the tip (precision part) of the plunger
against the top wall of the syringe. Otherwise, the tip
may deform to cause a reduction in service life or a
breakage of the syringe.
Do not push forcedly.
