R 474 / T 653 Telescopic stand:
The stand pillar must always be lightly oiled, so that raising and low-
ering is not made more difficult due to increased friction.
Apart from this, the telescopic stand is maintenance-free.
Cleaning:
- Use only cleaning agents which have been approved by IKA to
clean IKA devices: these are water (with tenside) and isoproApanol.
- Wear protective gloves during cleaning the devices.
- Before using another than the recommended method for clean-
ing or decontamination, the user must ascertain with IKA that this
method does not destroy the device.
Maintenance and Cleaning
Spare parts order:
When ordering spare parts, please give:
- device type.
- serial number, see type plate.
- item and designation of the spare part, see
www.ika.com .
Repair:
Please send the device for repair only after it has been cleaned
and is free from any materials which may constitute a health
hazard.
For repair, please request the “ Decontamination Certificate ” from
IKA, or download printout of it from the IKA website www.ika.com .
If you require servicing, return the device in its original packaging.
Storage packaging is not sufficient. Please also use suitable transport
packaging.
The stand pillar is inserted into the baseplate so that the guide groove
is at the back. The black handwheel bolt is then on the right. The
stand pillar is then secured from below with a hexagon nut, toothed
lock washer and a large shaped washer.
All four rubber feet are height-adjustable, so the stand can be set up
so it does not rock, even on uneven floors.
In addition, a hole is provided in the baseplate of the
R 474 Tele-
scopic stand , for screwing on a 16 mm diameter support rod. A
clamp can be fixed on this rod.
Mounting the unit:
The RW 47 digital agitator unit or the T 65 basic / digital
ULTRA-TURRAX
®
dispersion unit are placed on the arm of the
stand and bolted on from below with the bolts supplied. The help
of an assistant is needed for screwing on the
T 65 basic / digital
ULTRA-TURRAX ® dispersion unit.
The cable clips included in the delivery package are required for fixing
the power cable of the unit.
Safety disconnection device :
The height-adjustable telescopic stand must be fitted with a safe-
ty disconnection device. We recommend installation of the
SI 400
safety limit switch together with the SI 472 / SI 474 clamp support.
You will find information on their installation in the operating instruc-
tions of the units.
Commissioning (R 474 / T 653 Telescopic stand):
The stand can be raised and lowered by loosening the handwheel
bolt. The integral gas shock absorber helps to keep the manual force
needed for this as light as possible. The manual force must be applied
close to the stand pillar, so that the stand can be raised and lowered
with only a slight use of force. If the force for raising or lowering is
applied at a distance from the stand pillar, a turning moment results,
leading to increased friction on the pillar guide. As a result, the stand
can only be moved with great difficulty, or cannot be moved at all.
Besides this, the danger of the stand toppling over is increased.
When the unit is at the correct height, the handwheel bolt is tight-
ened by hand. Check the tightness of the handwheel bolt regularly
when using the unit, and retighten it if necessary.
Setting up the stand (R 474 / T 653 Telescopic stand):
