RUP1 maintenance
CAUTION: Always refer to the 'Safety' and 'Warnings' sections of this guide. Failure to do so could lead to personal injury.
Following the simple procedures given below will prolong the operational life and maintain the high performance of the system. The user should determine the frequency of inspection and maintenance actions according to the conditions of use.
All system components should be cleaned using a soft, lint free cloth and must be kept dry.
Kinematic couplings
The kinematic coupling mechanisms incorporated throughout the system have precision ball seating and permanent magnets. It is recommended that all these features be cleaned before first use, and thereafter at regular intervals.
A cleaning kit for the precision ball seating and permanent magnet is available from your Renishaw supplier (part number A-1085-0016). It comprises strips of yellow tack material. Use the yellow tack to clean the areas indicated with arrows on the image below.

With clean hands, tear off a small piece, shape into a small ball and press into / onto each of the features in turn, rotating to a fresh piece of material as you work around.
CAUTION: Ensure no yellow tack debris is left on the surface. The yellow tack should not be used for electrical contacts.
Electrical contacts
The electrical contacts, indicated with arrows in the image below, should be carefully cleaned with an alcohol-based cleaner (e.g. IPA) and a lint-free cloth.

Rack port maintenance
Periodic cleaning of the ports, lids and outer surfaces using a soft, lint free cloth is recommended to prevent contamination of stored probes and modules.
ULA maintenance
Periodically visually inspect the ULA for scratches and wear, and replace if necessary. Cleaning with a lint free cloth at regular intervals is recommended.
