10. Maintenance

This section describes the basic maintenance procedures, in particular, the methods and materials used for

cleaning the centrifuge, rotors and accessories.

Cleanliness

Drive shaft

Rotors and

buckets

0-Rings

Lid friction

block

adjustment

To maintain a good appearance and to prevent dirt build-up, the casing and the

inside of the bowl shouid be cleaned regularly using a soft cloth dampened with a

neutral detergent and warm water. The key pad and display may also be cleaned in

this manner, but shouid be wiped dry immediately.

If corrosive materials are used in the centrifuge, it is especially important to clean out

the centrifuge bowl thoroughly. Pay particular attention to the cooling air louvres. If a

major spillage occurs in the bowl, the excess liquid shouid be mopped out and the

bowl then removed for final cleaning (refer to page 16 for bowl removal procedure).

The drive shaft shouid be cleaned periodically with a solvent to remove excessive

grease. When clean, re-lubricate the shaft lightly with petroleum jelly.

The rotors and accessories shouid be handled with care to avoid damage. Prior to

storage, all components shouid be protected against corrosion using MSE Rotor

Spray (Cat No 17341-151) which is an anti-corrosion and de-waterizing agent.

The rotors, metal buckets, cups, carriers and adaptors shouid all be washed after

use with a neutral detergent and afterwards dried and stored in a dry place. Buckets

and cups shouid 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, shouid be lubricated periodically with Molykote 321 R grease (a spray

can is the most convenient application method).

Ensure that the 0-Rings fitted to the sealing caps are lightly coated with silicone

grease. Check the 0-Rings regularly for cuts and abrasions, replacing as necessary

but at least once a year.

Mistral 2000 only - In the event that the lid fails to lift off its catch when the open lid

key is depressed then it is most probable that the lid friction block needs adjustment.

Open the lid manually (see page 12), then turn clockwise the small socket screw,

which is visible through the small hole that is located on the underside of the lid

towards the centre-rear of the machine. A key is supplied with the machine for this

purpose.
