Maintenance and cleaning
The equipment is maintenance-free. It is only
subject to the natural wear and tear of compo-
nents and their statistical failure rate.
Cleaning
For cleaning unplug the
equipment!
Use only cleaning agents which have been ap-
proved by IKA
® to clean the instruments.
Dirt
Cleaning agent
Dye isopropyl alcohol
Construction
material water containing tenside/
isopropyl alcohol
Cosmetics water containing tenside/
isopropyl alcohol
Foodstuff water containing tenside
Fuel water containing tenside
For materials which are not listed, please request
information from IKA
® application support.
Wear protective gloves during cleaning the devices.
Electrical devices may not be placed in the cleansing
agent for the purpose of cleaning.
Do not allow moisture to get into the equipment
when cleaning.
Before using another than the recommended
method for cleaning or decontamination, the user
must ascertain with IKA
® that this method does
not destroy the instrument.
When cleaning the unit, take particular care not to
bring substances containing oil or grease into con-
tact with the running surfaces of the cone pulley and
the friction wheel. This would substantially reduce
the frictional coefficient resulting from the pairing
of the friction wheel and cone pulley materials, and
would impair power transmission in the unit.
Spare parts order
When ordering spare parts, please give:
- machine type
- manufacturing number, see type plate
- item and designation of the spare part see
www.ika.com, spare parts diagram and spare
parts list
- software version.
Repair
Please send in equipment 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” form IKA ® or use the download
printout of it from IKA ® website: www.ika.com.
If you require servicing, return the equipment in its
original packaging. Storage packaging is not suffi-
cient. Please also use suitable transport packaging.
DANGER
During commissioning of the machine the output
shaft starts to run at the speed setting in last op-
eration. Therefore check the setting of the control
knob (speed). Also ensure that the speed set is
suitable for the test medium selected. If you are un-
sure, set the motor slide to the lowest speed (front
motor slide stop) using the rotary control knob (C)
on the side and the gear to the lowest level. The instrument will start up when you press the
ON switch (A) on the motor.
If the unit has not been used for some time, a
knocking noise will be heard when switching on,
which is due to the preload on the friction lining
of the friction wheel drive. This has no detrimental
effect on the function of the unit, and the knocking
noise will disappear after a short running-in period.
