8 Maintenance
WARNING: Disconnect power to the unit
before servicing to avoid exposure to high
voltages and/or temperatures which may result
in personal injury or death. If you have any
questions about maintaining your equipment,
then please do not hesitate to contact the
Koehler technical service department.
8.1 Routine Maintenance
The KV4000 Kinematic Viscosity System
requires little routine maintenance to provide
many years of continuous service. However,
over the course of time, some instrument parts
may need to be replaced. When ordering
replacement part(s), please provide the model
number, serial number, and product shipment
date of your equipment so that we can ensure
you will receive the proper replacement part(s).
8.2 Bath Cleaning

To clean
the instrument’s exterior, which
includes all painted surfaces and glass,
either a solution of soap and water or
laboratory grade detergent may be used.

Apply cleaner to clean wipe or cloth, not to
the instrument directly. Wipe surface clean.

Do Not clean bath exterior with organic
chemicals such as Acetone, Toluene,
Hexane, etc.

For more difficult cleaning of finished
surfaces, a dilute solution or isopropanol in
water may be used.

It is not recommended that more aggressive
solvents be used on painted surfaces since
paint color will tarnish or be stripped from
the instrument.

Stainless Steel surfaces, such as on the top
plate, may be cleaned using a more
aggressive solvent such as a stainless steel
cleaner.

Glass surfaces may be cleaned using a
more aggressive solvent such as acetone, if
necessary.
