Samples may be dangerous substances. Fully understand the properties of the samples to be
measured, and handle them appropriately.
Fire
• For your safety, make sure to unplug the power plug from the electrical outlet when not in use.
• Clear dust on the power plug periodically (a few times a year).
If the power supply cord is left plugging into the electrical outlet for a long period of time, electrical
tracking may occur due to dust and moisture, and it may result in an ignition or a fire.
Fire or electric shock
• Do not bundle the power supply cord during use.
• Do not damage, bend, or stretch the power supply cord forcibly.
• If it cannot be plugged into an electrical outlet firmly, stop use of the power supply cord.

CAUTION
Chemical hazard (solvent S-316)
Inhalation or accidental ingestion of a large amount of solvent S-316 may be harmful.
Observe the following rules when handling:
• Ventilate the work area sufficiently.
• Wear a protective mask and protective gloves.
• Wash hands well after handling the solvent.
Chemical hazard (hydrochloric acid)
Hydrochloric acid is toxic by skin or eye exposure.
If it touches the skin, immediately rinse with water.
If it reaches the eyes, rinse immediately under a large amount of running water and get medical
attention.
During dispensing liquids into the extraction tank, limit the solvent amount to 10 mL or less and the
amount of the measurement liquid to 20 mL or less, so that the total volume of liquid does not exceed
the upper limit line (30 mL).
If the liquid exceeds the upper limit line, the liquid may leak and cause short-circuit in the internal
wiring of the product. If liquid containing hydrochloric acid leaks and comes in contact with the skin,
irritation and burning may occur.
Discard the liquid collected in the beakers before overflow.
If liquid containing hydrochloric acid overflows and comes in contact with the skin, irritation and
burning may occur.
