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

• Vibrations may loosen the hand screw on the flange of the drive unit. For
your own safety check that the hand screw is secure and tighten it if
necessary.
•
Glass vessels must always be secured with a clamp to prevent them
spinning. When working with flasks elastic couplers must be used to
prevent fracture of the glass.
•
Switch on the drive only at the lowest speed setting. Then gradually
increase the speed to the desired level.
• When working with the R 50 agitator shaft the safety cage must not be
removed. The agitator shaft must be installed in the T 50 basic drive unit
such that the bent safety cage prevents any direct contact with the shaft
from in front.
• Only dispersion and agitating tools approved by IKA may be used!
• Even in the case of repair work, the unit must only be opened by a
qualified engineer. The mains plug must be pulled before opening the
unit. The voltage-carrying components inside the unit may continue to
carry a voltage for some time after the mains plug is pulled.
• 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.
