Safety instructions
• The unit is not suitable for manual operation.
• Observe all pertinent safety instructions and directives, as well as work-
safety and accident-prevention regulations for laboratory use.
• The unit must not be operated without a dispersion tool.
• Never run dispersion tools dry, as the gasket and bearings will be
032009
destroyed if the tools are not cooled by the medium.
• The gasket and bearings are made of PTFE and rustproof steel; the
following points should therefore be noted: Chemical reactions of PTFE

occur in contact with molten or solute alkali metals and alkaline earth
15
metals, as well as with fine powders of metals in groups 2 and 3 of the
16
periodic system at temperatures above 300 °C - 400 °C. Only elementary
16
fluorine, chlorotrifluoride and alkali metals attack it; halogenated
16
hydrocarbons have a reversible swelling effect.

• Vibrations may loosen the hand screw on the flange of the drive unit. For
17
your own safety check that the hand screw is secure and tighten it if
17
necessary.
18
• Glass vessels must always be secured with a clamp to prevent them
18
spinning. When working with flasks elastic couplers must be used to
19
prevent fracture of the glass.

• Switch on the drive only at the lowest speed setting. Then gradually
20
increase the speed to the desired level.
21
• When working with the R 50 agitator shaft the safety cage must not be
21
removed. The agitator shaft must be installed in the T 50 basic drive unit
22
such that the bent safety cage prevents any direct contact with the shaft
22
from in front.
22
• Only dispersion and agitating tools approved by IKA may be used!
23
• Even in the case of repair work, the unit must only be opened by a
24
qualified engineer. The mains plug must be pulled before opening the
24
unit. The voltage-carrying components inside the unit may continue to
124
carry a voltage for some time after the mains plug is pulled.
125
• Caution: Pull the mains plug before changing the dispersion heads!
• Caution: Continuous operation will cause the surface of the mounting
flange for the dispersion tool to become hot!
• The ventilation slots on the drive must not be obstructed!
• The device does not start up again after a current failure. Switch device
off and on.
• The T 50 basic may not be used to process inflammable or explosive
media.
