Installing and Removing the Rotor
CAUTION!
Before fitting the rotor, make sure that the rotor chamber is free of impurities (dust, splinters of
glass, or similar). Condensed water or the remains of test liquids must be removed before centri-
fuging!
Handling the wind protection boiler rotor
WARNING!
The wind protection boiler rotor must only be carried by the steel cross and with the lid removed.
Never transport the rotor carrying by the wind protection boiler!
Due to the weight of the rotor (approx. 25 kg) it should only be carried by 2 people. It must be ensured that
the thin-walled aluminium boiler does not get dented or damaged in any way, which can lead for example to
serious malfunctions during operation and damage to the centrifuge.
Installing the rotor
After positioning the rotor on the primary shaft, it is secured as follows:
1. Put the 10 mm socket spanner through the central rotor bore hole on the hexagon of the conical primary
shaft.
2. Hold the rotor flanged nut in position with the 19 mm open jawed spanner.
3. Turn the primary shaft anticlockwise with the 10 mm socket spanner until it stops.
4. Tighten the flanged nut with the 19 mm open jawed spanner (in a clockwise direction), in the other hand
holding the rotor by the rotor cross.
5. Position the box level centrally on the flanged nut and accurately level the drive using the feet.
6. Securely tighten the counter nuts of the stand feet and screw in the safety hooks to the feet using the
size 8 open jawed spanner.
Lubricating the swing bearing bolts
CAUTION!
The retaining bolts of the swing rotor must always be lightly lubricated!
The swinging action of the buckets and the balance of the centrifuge are positively influenced by the lubri-
cation film, particularly during acceleration and deceleration.
The friction surfaces should be lubricated with sliding grease on a daily basis, or at least after every 10 runs.
Before lubrication, the bolts and the retaining grooves of the swing buckets must be thoroughly cleaned
using a dry cloth.
CAUTION!
Under no circumstances must organic solvents, alkaline cleaners or household cleaners containing
scouring powder be used!
The suitable lubricant is available from KENDRO Laboratory Products, order number 70006692.
Molykote lubricants and lubricants containing graphite are not permitted!
