8. MAINTENANCE
This section describes the basic maintenance procedures, in particular, the
methods and materials used for cleaning the centrifuge, rotors and accessories.
To ensure reliability and safety it is recommended that a inspection of the
centrifuge is made after 1000 hours of operation, or at least once per year
whichever is the sooner, this should include rotors and accessories.
Electricity at Work Regulations (1989). Portable Appliance Testing (PAT) -
where applicable this centrifuge should be inspected and tested regularly in
accordance with these regulations and the appropriate records kept.
For Warranty Service and Maintenance please see the details given at the front
of this manual.
8.1 Cleanliness
To maintain a good appearance and to prevent dirt build-up, the casing and the
inside of the bowl should be cleaned regularly using a soft cloth dampened with
a neutral detergent and warm water. The control panel and display may also be
cleaned in this manner, but should be wiped dry immediately.
If corrosive materials are used in the centrifuge, it is especially important to
clean out the centrifuge bowl thoroughly. If a major spillage occurs in the bowl,
the excess liquid should be mopped out and the bowl then cleaned using a
suitable cleaning agent.
8.2 Drive shaft
The drive shaft should be cleaned periodically with a solvent to remove
excessive grease. When clean, re-lubricate the shaft lightly with petroleum jelly.
8.3 Rotors and buckets
The rotors and accessories should be handled with care to avoid damage. Prior
to storage, all components should be protected against corrosion using MSE
Rotor Spray (Cat No. 17341-1512) which is an anti-corrosion and de-waterizing
agent.
The rotors, metal buckets, cups, carriers and adaptors should all be washed
after use with a neutral detergent and afterwards dried and stored in a dry
place. Buckets and cups should be stored inverted.
The pivot areas of the swing-out rotors, i.e. the pivot pins on the rotor and the
slots on the buckets, should be lubricated periodically with Molykote 321 R anti-
friction coating (a spray can is the most convenient application method).
