Manual No. M/92-021-N0902

❏

Remove and return all spindles (properly packed
for shipping).

❏

Clean excess testing material off the instrument.

❏

Include MSDS sheets for all materials tested with
this instrument.

❏

Support pointer shaft with white, nylon shipping
cap, as shown in Figure K1, or with white plastic
shipping cap originally supplied with instrument.

❏

Pack the instrument in its original case.  Cases
are available for immediate shipment from
Brookfield.    If the case is not available, take
care to wrap the instrument with enough material
to support it.  Avoid using foam peanuts or
shredded paper.

❏

DO NOT send the laboratory stand unless there
is a problem with the upright rod, clamp or base.
If there is a problem with the stand, remove the
upright rod from the base and individually wrap
each item to avoid contact with the instrument.
Do not put lab stand in viscometer carrying case.

❏

Fill out the Viscometer Information Sheet with
as much information as possible to help expedite
your service.  If you do not have this form, please
include a memo indicating the type of problem
you are experiencing or the service you need
performed.  Please also include a purchase order
number for us to bill against.

❏

Package the instrument and related items in a
strong box for shipping.  Mark the outside of the
box with handling instructions.

Example: "Handle with Care" or

"Fragile - Delicate Instrument"

For cone/plate instruments, please remove the cone spindle and carefully pack in place
in the shipping case.  If available, use the original foam insert or roll up one sheet of
tissue paper (or similar) and place between the spindle coupling and cup assembly (see
Figure K2).  This will help prevent damage in shipping.
