defective at the time of deliver

y, p

rovided that it does not fall unde r the exceptions and conditions

s

p

ecified in this warranty. Such exception and conditions include, but are not limited to, failure

due to natural wear and tear

,

accident, negligence, alteration, repair, or operation in a manner not

p

rescribed in the Instruction Manual supplied with the instrument. The foregoing expresses

Kubotas sole warrant

y

with respect to the instrument.

THIS WARRANTY IS MADE IN LIEU OF ANY AND AL L OTHER WARRANTIES AND ALL

IMPLIED WARRANTIES OF MERCHANT ABILITY AND FITNESS FOR A PARTICULAR

PURPOSE ARE HEREBY DISCLAIMED AND EXCLUDED.

original customer to whom this warranty is originally delivered.

Use of Model 2420

Model 2420 can be used for

prep

rocessing in in-vitro analysis, which breaks down blood or urine

samples containing plasmas or cells. Accordingly, it is not designed to connect directly to a

p

atient's body.

Do not use the centrifu

g

e for separation of any hazardous material (explosive, chemically active,

or

g

anic, or radiation containing material, or material contaminated by pathogenic microorganisms

)

or oil.

Use of rotors beyond the lifetime may lead to breakage of the rotor.
If the rotor is used continuousl

injury or death.

WARNING

Usable Rotor

Lifetime of rotors

Lifetime of rotors is 7 years after the delivery.

When 7 years have passed after the delivery, discon tin ue operation of the centrifuge to replace the
rotor with a new one.
Earlier re

p

lacement, however, is required if any corrosion, lowered strength, flaw or deform due to

incorrect o

p

eration is detected on the rotor.

In such cas e, contact

y

our local dealer and be sure to have the rotor checked before reusing it.

WARNING

（１）

Do not use an

y

rotors other than those speci fied in (2) below.

If rotors other th an thos e s

p

ecif ied are used, the rotors may be broken, resulting in

a serious accident.

（２）

The rotors that can mount as of Ma

y

2005 are as follows:

RMP-23

Stop the use of the rotor immedi ately when it is used beyond the number of

times allowed for autoclavin

g

. Otherwise, the rotor may deteriorate by the heat

g

enerated by autoclaving, res ul ting in deformation or destruction.

Should the rotor

g

et damaged, the main unit of t he centrifuge suddenly may

start to rotate

;

this could result in an accident causing injury or death.

WARNING

Ⅴ

Number of times allowed for autoclaving of rotor

The number of times allowed for autoclavi ng of each rotor should be deemed as follows.

When the followin

g

conditions has been met, discontinue operation of the centrifuge to

re

p

lace the rotor with a new part.

Earlier re

p

lacement, however, is required if any corrosion, lowered strength, flaw or deform

due to wron

eration is detected on the rotor. In such case, contact your local dealer and

be sure to have the rotor checked before reusin

WARNING

When installing this centrifuge, keep 3meters or more away from AM radio.
Noise
