Switching On The Machine; Output Shaft; Maintenace And Cleaning - IKA RW 47 D Mode D'emploi

Switching on the machine

Check whether the voltage given on the type plate corresponds to the
available mains voltage. The socket used must be earthed (fitted with
earth contact). If these conditions have been met, the machine is
ready to operate when the mains plug is plugged in. If these conditi-
ons are not met, safe operation is not guaranteed and the machine
could be damaged.
When working with safety switch SI 400, the appliance only starts up
once it has been set to the designated working height and the switch
contact activates the safety switch.
During commissioning of the machine the output shaft starts to run at
the last speed set. Therefore check the setting of the control knob
(speed). Also ensure that the speed set is suitable for the test textu-
re selected. If you are unsure, set the motor slide to the lowest speed
(front motor slide stop) using the side knob and the gear to the lowest
level (fig. 2).
The appliance will start up when you press the ON switch on the
motor (fig. 2).
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.

Output shaft

The chuck ((E) - fig. 2) and off-drive shaft allow stirring elements with
shank diameters of 3mm to 16mm to be clamped. Shank diameters of
up to 13mm can be inserted through the hollow shaft to just before the
top edge of the inside ccasing. You must ensure that the stirring shank
is securely clamped in the chuck.

Maintenance and cleaning
The stirrer is maintenance-free. It is subject only to the natu-
ral wear and tear of components and their statistical failure
rate.
When ordering spare parts, please give the manufacturing
number shown on the type plate, the machine type and
the name of the spare part.
Please send in equipment for repair only after it has been cle-
aned and is free from any materials which may constitute a
health hazard. Use only cleansing agents which have been
approved by IKA to clean IKA devices. To remove use:
Dyes isopropyl alcohol
Construction materials water containing tenside / isopropyl alcohol
Cosmetics water containing tenside / isopropyl alcohol
Foodstuffs water containing tenside
Fuels water containing tenside
For materials which are not listed, please request information
from IKA. Wear the proper protective gloves during cleaning of
the devices.
Electrical devices may not be placed in the cleansing agent for
the purpose of cleaning.
When cleaning the unit, take particular care not to bring sub-
stances containing oil or grease into contact 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.
Make certain that the hexagon head nut (part no. 153 of spare
parts diagram) is sufficiently tightened in order to prevent the
shifting of the motor plate and thus the speed as well.
