CAUTION: This note indicates a potentially hazardous situation, which if not strictly observed, could result in personal injury or severe damage to the

instrument.

1. Do not use any sample inapplicable to the tubes, the bottles, the tube racks, the micro-plates or tube/bottle caps, etc. Using such a sample could deteriorate them.

Maximum rotor speed depends on the buckets, assemblies, tubes or adapters to be used.

2. Do not exceed the allowable imbalance.

3. Use the rotor tubes and bottles within their actual capacities.

4. Mount the rotor onto the drive shaft gently and properly. Do not drop the rotor or apply excessive force to the drive shaft to avoid damage to the drive shaft. Please see the picture and video!

5. Clean the inside of the drive hole (crown hole ) of the rotor and surface of the drive shaft (crown) of the centrifuge once a month.

6. If dew drops are in the rotor chamber, drain the chamber through the drain hose to prevent the sample to get mixed up with them or prevent them from leaking into the drive unit. Be sure to recap the drain hose after drainage.

7. Do not pour any solution such as water, detergent and disinfectant directly into the rotor chamber. Otherwise, the bearings of the drive unit may be corroded or deteriorated.

8. Before relocating the centrifuge, remove the rotor from the rotor chamber to avoid damaging to the drive shaft.

"NOTE" indicates a note which has no direct bearing on personal safety

Safety During Installation and/or Maintenance

WARNING: 1. Level he centrifuge by using the four level adjusters and secure them completely. Improper securing can cause significant movement of the centrifuge in the event of rotor disengagement.

2. When servicing the centrifuge, be sure to turn off the POWER switch, turn off the distribution board of your centrifuge room, and then wait for at least three minutes before removing covers or tables from the centrifuge to avoid electrical shock hazards.

CAUTION: Avoid a place exposed to ultraviolet rays for operation or storage of the centrifuge. Otherwise, the covers can be discolored and the coating can be peeled off easily. If installation in such place is unavoidable, cover the centrifuge with a cloth after operation to protect from ultraviolet rays.

Electrical Safety

WARNING: Your centrifuge must be grounded properly to avoid electrical shock hazards. And this BCFL-302-B centrifuge is 220V±20V 2A.

CAUTION: Do not place containers holding liquid in the rotor chamber or on or near the instrument. If they spill, liquid may get into the instrument and damage electrical components.

Safety against Risk of Fire

WARNING: This instrument is not designed for use with materials capable of developing flammable or explosive vapors. Do not centrifuge such materials in this instrument nor handle or store them near the instrument.

Chemical and Biological Safety

WARNING: 1.Make sure to prepare necessary safety measures before using samples that are toxic or radioactive samples or pathogenic or infectious blood samples at your own responsibility.

2. If the centrifuge, rotor or the accessory is contaminated by toxic or radioactive samples or pathogenic or infectious blood samples, be sure to decontaminate it according to good laboratory procedures and methods.

3. If there is a fear that the centrifuge, rotor or the accessory is contaminated by toxic or radioactive samples or pathogenic or infectious blood samples that impair human health, it is your responsibility to sterilize or decontaminate the centrifuge, rotor or the accessory properly.
