IKA T 65 D ULTRA-TURRAX Mode D'emploi page 22

Assemble the generator on the shaft as fol-
lows:
1. Screw the stator on to the stator tube counter-
clockwise by hand. Note the left-hand thread!
2. Gently tighten the stator with the hook wrench.
The stator is turned in the same direction later,
by the fl ow pressure of the rotor, and hence
cannot come loose.
ATTENTION!
3. Screw the rotor clockwise on to the shaft
(right-hand thread). To do this, hold the shaft
with the shaft wrench at the coupling section
and tighten the rotor with the rotor wrench.
With the G 65 G generator, the rotor wrench
is inserted between the teeth of the stator and
turned.
Mounting the dispersion tool on the unit
The dispersion tool must only be mounted on
the dispersion unit when the mains plug is
pulled out and the drive shaft is stationary.
The pre-assembled element, consisting of shaft
and generator, is now connected to the T 65 D
ULTRA-TURRAX
the pre-assembled dispersion tool in the dispersion
tool receptacle (C)
® dispersion unit. To do this, insert
and secure it with the handwheel bolt. Make sure
that the shaft is inserted right up to the stop in
the receptacle. It can be helpful to turn the shaft
lightly as it is inserted. The tool is locked in positi-
on by tightening the handwheel bolt. Make sure
that the handwheel bolt is securely tightened, and
also check the tightness frequently when the unit
is in service.
Cleaning the shaft and generator
The shaft must be cleaned immediately after the
unit has been used. This prevents any substance
residues adhering to the rotor and stator threads,
or bacteria cultures forming in undesired places.
Run the dispersion tool in a solvent which will dis-
solve substance residues but not harm the seals.
As a result, because of the high fl ow speeds, the
rotor and stator will then only be lightly soiled.
Do not put the dispersion tool in a vessel
containing solvent to dissolve substance re-
sidues. The seals are mainly dynamic-acting,
and quickly start to leak when stationary.
Clean the dispersion tools and shaft as fol-
lows:
1. With the drive switched off, dismount the di-
spersion tool from the drive by slackening the
handwheel bolt.
2. Unscrew the generator from the shaft.
The disassembly procedure is the reverse of
the assembly procedure (see "Pre-assembly of
dispersion tool").
The stator can be very tightly seated on the shaft
tube, particularly when working with viscous
substances, or when cleaning has been neglec-
ted, or when medium has penetrated into the
thread between shaft tube and stator. In this
case, the shaft tube can be held in a vice with
soft jaws to crack the thread. Note the left-hand
thread!
