WEEE Directive Compliance Statement
Background
The goal of the WEEE Directive is to encourage design of environment-friendly products that increase reuse,
recycling and other forms of recovery to reduce waste streams and applies to listed Electronic and Electrical
Equipment (EEE) and Koehler's equipment falls broadly into Appendix 1A; Section 9 Monitoring and Control
Equipment: Measuring, weighing or adjusting appliances for household or as laboratory equipment.
Any associated non-embedded equipment such as Lighting (Saybolt Color) and PCs/Printers also fall under
WEEE. If provided with an order these ancillary items must be WEEE compliant. For these and other
reasons (printer cartridges are regionalized) the equipment must be supplied through a third party supplier in
Europe.
The WEEE Directive applies to electrical and electronic equipment falling under the categories set out in
Annex IA provided that the equipment concerned is not part of another type of equipment that does not fall
within the scope of this Directive. Annex IB contains a list of products which fall under the categories set out
in Annex IA.
http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:037:0024:0038:en:PDF
We do not qualify for any of the 10 exemption categories.
http://www.dpa-system.dk/en/WEEE/Products/Exemptions
Professional use
For equipment defined for ’professional use’ local authorities have no role to play. Producers and importers
are basically responsible for collection of WEEE recyclables from the professional user and for subsequent
management. A separate statement is given cataloging the items that require separation from the equipment
along with basic information on subsequent processing or recycling prior to disposal of the equipment.
http://www.dpa-system.dk/en/WEEE/Products/Private-or-professional-use
Responsibility for Registration and Annual Reporting:
Koehler will not sell directly to end users in the EU and so has no responsibility to register within each EU
state and to make annual reports. Koehler declares that this responsibility is born by the importer who is the
first level of the distribution chain and is subject to producer responsibility. We will communicate this in
writing to our distributor/importers in the EU stating they are responsible to satisfy WEEE registration and
reporting requirements in the EU states where they conduct sales activities.
It is illegal to market electrical and electronic equipment covered by producer responsibility without being
registered.
http://www.dpa-system.dk/en/WEEE/Producers/Whoissubjecttoproducerresponsibility
Product Design
Koehler's designs allow for complete disassembly to a modular level which usually allows for standard
recycling. A qualified refrigeration system technician must be consulted when disassembling and de-
commissioning any equipment with refrigeration systems.
Koehler's scientific testing equipment is robustly designed to function over a long service life and are typically
repaired many times over the course of years rather than being replaced. We believe that re-use and
refurbishment is the very best form of re-cycling.
All batteries must be readily removable not soldered in place.
Recycling instructions
In the event that replacement becomes necessary, we will include instructions, particularized to each
instrument that informs the customer of their recycling responsibilities and giving them guidance in doing this.

K1798X Corrosion Preventative Properties Apparatus
Operation and Instruction Manual
K1798X-Manual -4-
All Koehler equipment has been placed on the market since 13th August 2005 and so Koehler is defined as a
"new WEEE producer". As such we must provide information on refurbishment, treatment, and re-use.
Our instrument manual will include this compliance statement and indicate that any collection of materials will
be handled by their authorized distributor. In the event that the distributor is unreachable or is no longer a
distributor for Koehler Instrument, Co., other arrangements may be made including accepting the materials
directly.
Recycling is free of charge. Shipping is the responsibility of the end users. Whether shipping to a distributor or
to Koehler directly, safe, properly declared, and labeled packaging and shipping expenses are the sole
responsibility of the end user.
WEEE Marking
Since Koehler products are subject to the WEEE Directive we must display the WEEE symbol shown above
in accordance with European Standard EN 50419 on the equipment. It must be indelible, at least 5mm in
height, and clearly legible. If the equipment is too small the mark must be in the product literature, guarantee
certificate, or on the packaging. Rules on marking are established in section 49 of the WEEE Order.
Koehler Instrument Company, Inc.
c/o RECYCLING
1595 Sycamore, Ave.
Bohemia, NY 11716

5 Operation
5.1 Preparation of Bearings
1. Only bearings that have outer races and
rollers entirely free of corrosion should be
tested. Bearings should not be handled
without the use of tongs or rubber or
plastic gloves.
2. Wash the selected bearing thoroughly in
hot (52 to 66°C) mineral spirits reagent
grade to remove rust preventative
WARNING: Mineral spirits is highly
combustible and vapors are hazardous. The
washing temperatures are considerably above
the flashpoint. All washing should be carried
out in a well ventilated hood with no flames or
ignition source present.
3. Moisten a tissue in hot solvent and wipe
the bearing cup and cone to remove
remaining residue.
4. Rinse bearing again in hot mineral spirits,
reagent grade.
5. Transfer bearing to the solvent rinse
solution to remove the mineral spirits.
WARNING: Poison. Fatal if swallowed,
harmful if inhaled. Causes burns. Vapor
extremely irritating.
6. Rinse the bearing and slowly rotate in 66
± 5°C solvent rinse solution.
7. Remove the bearing from the solvent rinse
solution and place on filter paper to drain.
Dry the bearing in an oven at 70 ± 5°C for
15 to 30 minutes.
8. Permit the bearing to cool to room
temperature and re-examine surfaces to
assure that all corrosion-free and free-
turning specimens have been selected.
9. Wash and dry the bearing packer using
the same technique as preparation of the
bearings.
5.2 Standardization of Thrust Loading
Device
1. To standardize the thrust loading device a
packed bearing must be prepared and
installed into a bearing holder assembly.
Refer to section 5.3 and 5.4 for a detailed
procedure of this preparation.
2. Place the prepared bearing holder
assembly onto the base of the motor drive
spindle and center it under the indexing
pin of the drive. See Figure 4 below:
Figure 4. Bearing Holder Assembly Placement
3. Lower the drive until the O-ring just
contacts the 1-kg weight. See Figure 5
below:
Figure 5. Spindle / Thrust Loading Device Placement
4. Run the lower adjustment nut (Figure 3,
item 8) of the depth gage located on the
back of the instrument to the metal guide.
NOTE: The metal guide runs along the
depth gauge and acts as two point of
contact for the upper and lower
adjustment nuts to limit the movement of
the apparatus when using the lever.

K1798X-Manual -11-
5. Place the 3mm spacer (Figure 2, item 4)
on top of this nut and bring the upper
adjustment nut (Figure 3, item 9) down to
the spacer.
6. Hold the upper adjustment nut in position,
then remove the spacer and run the lower
adjustment nut up and tighten it against
the upper adjustment nut.
7. When the O-ring located at the underside
of the Spindle / Thrust Loading Device is
compressed against the 1-kg weight to the
point where the lower adjustment nut hits
the metal stop guide, a 29 Newton (N)
load will be added to the bearing
assembly. This will give a total load on 39
N on the bearing.
8. Examine the O-ring periodically and
replace it if it shows any cracks or other
signs of deterioration.
9. The thrust loading device should be
standardized before use, once per day if
used daily. Standardization should be
performed again if there is any reason to
believe that the standardization might
have changed.
5.3 Grease Packing Procedure
1. The K17982 Mechanical Grease Packer
must be utilized to properly pack the test
grease into the bearing. Please refer to
