Maintenance and Cleaning

Except for necessary cleaning and the replacement of a
defective drive belt or ball bearing, the CERTOMAT ® S-II
is maintenance-free. The motor is a service-free
brushless motor of external rotor type. All bearings are
lubricated for their lifetime.
Disconnect the mains cable from laboratory grounded
socket before cleaning and/or maintenance and
service. Unintended starting of the shaking drive
during cleaning and maintenance can cause personnel
hazards.

3.5.1 Cleaning

1. For cleaning, we recommend usual household cleaning
agents or alcohol. Do not use aggressive cleaning
agents. Clorous agents, for instance, can cause
corrosion.
2. If the shaker is operated in humid or dusty
environment, regulary check the drive belt
for deposites or wear and tear.

3.5.2 Malfunction Correction

In case the device should not start or if it runs
irregularly:
1. Check at the mains supply whether the cable is properly
connected and laboratory mains supply is working. If
other devices in the laboratory are malfuncioning at the
same time, a distorted mains supply may be the cause.
Check and stop such a kind of interference.
2. Check the fuses on the rear of the shaker, see figure 3
on previous page. A melted or burned-off fuse link can
be detected visually. Disconnect the mains cable bevor
removing any of the fuses. Replace defective fuses.
•
For replacement note the correct voltage/current of the
fuses on the corresponding lable.
3. If the malfunctioning continuous after checking the
mains connection and replacement of defective fuses
please contact your Sartorius AG International´s service
representative, see address below.

At uneven and/or noisy operation or if the operation
stops unintentionally, the drive belt can be defective.
To check the condition of the drive belt, you'll have to
disassemble the trays and the tray support.
1. Unscrew the 4 screws of the tray support located in the
center and remove the table.
The tray support is heavy. Handle with care.
2. You'll see the drive belt through the opening in the top
cover of the device. If the drive belt is in good
conditionen, reassemble the tray support and the tray in
reverse order.
3. If the belt is defective or shows wear and test or sticky
deposits, which cannot be removed it must be replaced.
Replacement of the drive belt, other service measures and
repairs must be done by authorized service personnel
only.
