RW20d0506 13
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.
The chuck and off-drive shaft allow stirrer attachments with shank
diameters of up to 10mm to be clamped and inserted. The
opening at the top of the housing allows stirrer attachments to be
pushed up above the top edge of the housing, e.g. in order to
change the stirring bowl with the unit switched off.
If the stirring shaft cover is removed while the stirrer is statio-
nary, then the rubber membrane must be pushed back into the
opening of the housing so that this is properly closed. This is
the only way to ensure that working with the unit is safe and
that media cannot enter the equipment.
Please see section “Safety instructions“!
The appliance is maintenance-free.
Cleaning
Only use cleansing agents which have been recommended by IKA
Use to remove:
Dyes
isopropyl alcohol
Construction materials water containing tenside/ isopropyl alcohol
Cosmetics
water containing tenside/ isopropyl alcohol
Foodstuffs water containing tenside
Fuels water containing tenside
- Do not allow moisture to get into the appliance when cleaning
- Wear protective gloves during cleaning the devices.
The stirring tool must only be changed when the equip-
ment is stationary and the power supply is diconnec-
ted.
Attaching the stirring shaft protector
Please refer to assembly diagram
(Fig. 3)
Use a stirring shaft protector (O), e.g. R301, to provide protec-
tion against injury when working with the equipment.
Use the bolts (P) to attach the plastic half-shell pieces to the
stirrer (N), as shown in Figure 3. The screw (Q) can be used to
adjust the length of the stirring shaft protector.
Check that the stirring shaft protector is held in posi-
tion securely prior to each use and also at regular
intervals. The position of the stirring shaft protector
must only be adjusted when the equipment is statio-
nary and the power supply is disconnected.
Check whether the voltage given on the type plate corre-
sponds 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 conditions are not met, safe ope-
ration is not guaranteed and the machine could be damaged.
During commissioning of the machine the output shaft starts
to run at the last speed set. Therefore check the setting of the
control knob. Also ensure that the speed set is suitable for the
test texture selected. If in doubt, set the speed knob (B) to the
lowest speed (left-hand position).In case of doubt, turn the
speed knob (B) to the lowest speed (all the way left) and set
the gear train to the lowest reduction stage.
The unit starts to operate when the rocker switch is pressed.
Note: The rocker switch (A) is not a mains power switch !
