Never operate the equipment with the stirrer tools rotating
freely. Ensure that parts of the body, hair or items of clothing
cannot be trapped by the rotating parts. Pay attention when
setting the speed to any imbalance of the stirrer tools and
possible spraying of the medium to be stirred. Use a stirrer shaft
protection device!
The equipment is not suitable for manual operation. Please follow
the relevant safety instructions and guidelines, and occupational
health and safety regulations for use in the laboratory.
Avoid knocks and impacts on the lower end of the shaft and the
chuck gear teeth. Even minor, invisible damage can lead to im-
balance and uneven shaft action. Careful handling guarantees
safe working and the long life of the equipment.
Imbalance of the output shaft, the chuck and in particular the
stirring tools can lead to uncontrolled resonant vibrational
behaviour of the equipment and the whole assembly. Glass
apparatus and stirrer containers can be damaged or shattered by
this. It can cause injury to the operator, as can the rotating stirring
tool. If vibration of the equipment is noticed, the speed must be
reduced immediately in all cases until no more vibration occurs.
In this case exchange the stirring tool for one without imbalance
or remedy the cause of the imbalance.
Operating with a freely rotating shaft end is dangerous. Therefore
for safety reasons the stirrer tool is permitted to project over the
upper edge of the housing only when the machine is not running.
For correct operation, the rubber diaphragm must always be com-
pletely closed. Take care to ensure that the shaft never runs
directly in the rubber diaphragm and any friction with rotating
parts (stirrer shafts) is excluded.
The machine may only be opened by trained specialists - even
during repairs. The machine is to be unplugged from the mains
before opening. Live parts inside the machine may still be live for
some time after unplugging from the mains.

The basic RW 16 stirrer is suitable for stirring and mixing fluids
with low viscosity. It is designed for use in laboratories. For
correct use, the equipment must be secured to a fixed object.
Please unpack the machine carefully and inspect for damage. It is
important that any transit damage should be noted at the time of
unpacking. In certain circumstances it may be necessary to in-
vestigate immediately (post, rail or freight forwarder). The guaran-
tee covers: One RW 16 stirring machine, one extension arm, one
hexagonal socket screw, one hexagon socket offset screw key
and operating instructions.
In buying this machine you have chosen a high quality product.
Ease of use is guaranteed with its handy shape and simple ope-
ration. The housing offers protection against ingress of liquids.
The materials used and their precise identification make recycling
possible and simple, and enables re-use of the parts. The
generously proportioned cooling surfaces enable distribution and
transference of heat to be as even as possible. The two metre
long mains lead makes it possible to work on stands - even with
high glass apparatus under vapour extraction hoods - without
extension leads. The precision stirrer shaft is designed as a hol-
low shaft to allow the stirrer shanks to be inserted.
The speed of the RW 16 basic stirrers can be infinitely adjusted
by electronic means. The ball bearing equipped DC motor has a
quiet synchronous belt drive. The motor is controlled via a com-
puter-controlled speed regulator using pulse-width modulated vol-
tage (PWM). The whole drive unit is maintenance-free.
The machine is suitable for continuous operation. The motor cur-
rent is electronically limited. The machine has an anti-stall and
anti-overload system. If a fault occurs, a safety circuit immediate-
ly switches off the motor permanently via a relay.
To start the machine again after a fault, please operate the mains
switch. If the machine still does not work, please contact our
Service department.

The speed is set using the front knob(A). The scale from 1 to 10
corresponds to a speed range for the output shaft of 40 to 1200
rpm under nominal load. With no load the speed at maximum set-
ting of the knob (right position) is 1600 rpm, at minimum setting
of the knob (left position) 0 rpm. If viscosity increases due to the
process, the speed reduces gradually. If, however, the viscosity is
reduced by eg the addition of thinning agents, the speed increa-
ses somewhat. This can be balanced out in both cases by re-set-
ting the knob accordingly, provided torque does not exceed maxi-
mum torque. Please note that fluctuations in mains voltage wit-
hin the permitted tolerances may also cause minor fluctuations in
speed.
For correct use, the stirrer must be secured to a stable object
(eg R1822) with a cross-sleeve (eg R181). For safety reasons the
stirrer container should always be fixed with a tension-holder
(eg RH1).
For diagram see (Fig. 2)
The extension arm (X) has a step at its end with a cross hole. This
end is used to insert the extension arm into the hole on the back
of the machine. To do this, the cross hole in the extension arm
must point upwards. It must be brought into alignment with the
hole in the fixing rib on the back of the machine. To do this, press
the extension arm until it catches in the hole. Please do not use
force to do this. If it proves difficult to insert the extension arm,
light oiling may help. The hexagonal socket screw (Y) used for
fixing is inserted in the hole in the housing from above. The screw
is tightened using the hexagon socket offset screw key (Z).
Check that the extension arm is firmly seated. The screw may
loosen with vibration. Therefore as a precaution check from time
to time that the extension arm is still securely attached.
If necessary tighten the hexagonal socket screw.
You can also secure the hexagonal socket screw with adhesive,
but you are then unable to release the connection later
.
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 conditions are not met, safe operation is not guaranteed
and the machine could be damaged.
The machine is started by pressing the mains switch (B) into
position “l”. A green control light (C) signals the operating
condition “ON”.
During commissioning of the machine the output shaft starts to
run at the last speed set. Therefore check the setting of the con-
trol knob. Also ensure that the speed set is suitable for the test
texture selected. If in doubt, set the speed knob (A) to the lowest
speed (left-hand position).

The clamping chuck and output shaft permit all standard
commercial stirrer tools up to 10mm diameter to be gripped and
screwed in. The opening on the top side of the housing is closed
with a slotted rubber diaphragm. It is, however, possible for stir-
ring shafts to push out over the top edge of the housing eg during
change of container.
If it becomes necessary - depending on the layout of the equip-
ment - to allow the shaft end to project over the edge of the hou-
sing during operations, the rubber diaphragm should be removed.
Instead a stirrer shaft cover, which can be obtained as an acc-
essory, must be placed on the housing. If the stirrer shaft cover
is removed again, the rubber diaphragm must be pressed into the
housing opening again so that this is closed. This is the only way
of ensuring safe working and preventing any fluids from penetra-
ting the equipment.
Please see section ”Safety Instructions”!
The stirrer is maintenance-free. It is subject only to the natural
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 clea-
ned and is free from any materials which may constitute a
health hazard. Only use water with a detergent additive contai-
ning a surfactant for cleaning, or for heavier soiling isopropylal-
cohol.
