PH20systemmaintenance
General
Following the simple maintenance procedures given below will prolong the operational life and continued high
performance of the system. The user should determine the frequency of inspection and maintenance actions
according to the conditions of use.
The external surfaces of all system components, apart from the head labels that can be best cleaned with a
water damped cloth, should only be cleaned using a soft, lint free cloth. All parts should be kept dry.
The probe kinematic coupling mechanisms have a precision ball seating and permanent magnets. It is
recommended that all these features be cleaned before first use, and thereafter at regular intervals. The
frequency of cleaning depends on the local environment conditions, but should be at least every 500 changes.
A cleaning kit for the kinematic coupling is available from your local Renishaw supplier (Renishaw part number
A-1085-0016). It comprises strips of ‘yellow tack’ material. 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. The yellow tack should only be used for the magnets and kinematic contacts.
Styli
Stylus balls, threads and mating faces should be cleaned using a proprietary cleaning cloth or solvent. Stylus
balls should be regularly inspected for damage or ‘pick-up’ of component material. See Styli and accessories -
technical specifications guide (part number H-1000-3200).
CAUTION: Always adhere to the safety instructions given in this guide (General safety instructions).
Failure to do so could adversely affect the performance of the PH20 system and/or lead to personal injury.
CAUTION: The PH20 head has no user serviceable parts. In the event of a problem, please contact your
local supplier for assistance.
