observe this instruction may lead to faults.
User information.
This information helps you to use all
the functions optimally.
Assembly, operation and servicing.
Here you are
explained exactly what to do.
Proper use
This concrete mixer can be used for mixing concrete and
mortar both professionally and non-professionally.
Proper use includes adherence to the operating, maintenance
and repair instructions of the manufacturer and observance of
the safety instructions they contain.
Any other utilisation counts as improper use, especially mixing
combustible or explosive materials (fire and explosion hazard)
and use with foodstuffs. The manufacturer is not liable for
damages resulting from improper use, the user alone
shall bear the risk.
Unauthorised modifications on the device exclude a liability of
the manufacturer for damages of any kind resulting from it.
Only persons who are familiarised with the device and
informed about possible risks are allowed to prepare, operate
and service this device. Repair works may only be carried out
by us or by a customer service agent nominated by us.
Residual risks
Even if used properly, residual risks can exist even if the relevant
safety regulations are complied with due to the design determined
by the intended purpose.
Residual risks can be minimised if the “Safety instructions” and
the “Intended usage” as well as the whole of the operating
instructions are observed.
Observing these instructions, and taking proper care, will reduce
the risk of personal injury or damage to the equipment.
Risk of injury to fingers and hands when reaching with the
hand into the running mixing drum. Providing protection
against the danger of getting caught in the rotating stirring
grating would not be practicable (please refer to EN 12151).
Risk from electricity when using improper electrical
connections.
Touching live parts of opened electrical components.
In addition, in spite of all the precautionary measures taken, non-
obvious residual risks can still exist.
Operating times
Please observe as well the regional regulations for noise
protection.
Safety instructions
Take note of the following instructions to protect
yourself and others from hazards and injuries.
Observe local accident prevention and safety regulations in
the work area.
Do not touch, inhale (dust development) or eat the
cement or additives. Wear personal, protective clothing
(gloves, goggles and a dust mask) when filling and emptying
the mixing drum.
Set up and run the concrete mixer on a
solid, level base only (where it will not tip
over).
Make sure that there is no danger of tripping near the mixer.
Be sure that there is enough light.

Observe enough safety distance to the
concrete mixer. Prevent any contact to rotating or moving
parts of the machine.
Fill or empty the mixing drum only when the motor is running.
Observe the mixer's direction of rotation.
Do not alter the revolution speed of the motor, since this
controls the safe maximum operating speed, and protects the
motor and all rotating parts against damage due to excess
speed.
Concrete mixers which the manufacturer has not intended for
towed vehicle operation may only be run by means of a hand
wire pull.
Be absolutely sure to pull the plug before:
moving or transport
cleaning, maintenance or repair work
eliminating faults
checking connecting lines, whether these are knotted or
damaged
leaving unattended (even during short interruptions)
Check the machine for possible damage:
Before further use of the machine the safety devices must
be checked carefully for their proper and intended
function.
Check whether movable parts function perfectly and do
not stick or whether parts are damaged. All parts must be
correctly installed and fulfil all conditions to ensure perfect
operation of the machine.
Damaged safety devices and parts must be properly
repaired or exchanged by a recognized, specialist
workshop; insofar as nothing else is stated in the
instructions for use.
Damaged or illegible safety labels have to be replaced.
Store unused equipment in a dry, locked place out of the
reach of children.
Shockproof concrete mixers
(Protection Class II)
Only start the machine when the panelling is complete and
fully closed.

is used for repairs and insulation clearances are not altered.
Electrical safety
Danger to life and limb if not observed!
Connecting attachments must be designed in conformance
with IEC 60245-4 and marked H 07 RN-F, or comparable
models. Cross section of wires at least 3 x 1.5 mm² up to a
maximum length of 25 m. Wire cross-section at least 2.5 mm²
for lengths of more than 25 m.
Use only connecting attachments with a rubber plug device
for severe requirements that is protected against
spraying water.
Long and thin connection lines result in a potential drop.
The motor does not reach any longer its maximal power;
the function of the device is reduced.
Unwind the cable completely when using a cable drum.
Do not use the power cords for purposes they are not
intended for. Protect the cable against heat, oil and sharp
edges. Do jerk on the power cable when pulling the plug from
the socket.
Check connecting attachments for defects or ageing before
using them.
Never use defective connecting attachments.
When laying the connecting attachments, be sure that they
do get crushed or bent, and that the plug-and-socket
connection does not get wet.
Do not use any provisional electrical connections.
Never bridge over protective devices or put them out of
operation.
Only hook up the machine by means of a
fault-current circuit breacker: 30 mA!
A licensed professional electrician must make all electrical
connections and repairs, and observe local regulations in
doing so, especially those regarding protective measures.
The manufacturer or a company designated by the
manufacturer must attend to the repair of all electrical
parts on the machine.
Use only original spare. Accidents can arise for the user
through the use of other spare parts. The manufacturer is
not liable for any damage or injury resulting from such
action.
Start-up
Observe all safety instructions.
Setting up the machine:
Set up and run the concrete mixer on a
solid, level base only (where it will not tip over).
Keep the machine from sinking into the ground or floor.
Adhere to accident prevention regulations (danger of
tipping).
When setting up the machine, make sure that the mixing
drum can be emptied without obstruction.
Switching on and off
Be sure that
all protective devices are on the mixer and properly mounted.
all safety instructions are adhered to.
The on/off switch is located beneath
the motor housing. Switch the motor
on and off only at the switch.

Concrete mixer with threephase motor
After switching on the machine, you must check the mixing drum's
direction of rotation. When you look into the mixing drum, it must
turn to the left (counter-clockwise). (Observe directional arrow on
the mixing drum.). If the mixing
drum turns in the opposite
direction from the arrow, the
rotating direcion can be
changed by inderting a
screwdriver for this purpose
and turn left or right while
exerting a light pressure to
adjust the correct rotating direction.
Mixing

Cleaning
Additional safety instructions
Pull plug each time before cleaning.
Switch off machine and pull plug if you have to touch the
machine (with hand, brush, scraper, rag, etc.) while cleaning
it.
Protective devices removed for cleaning must be properly
remounted before starting the machine.
Do not spray water directly on the motor or the switch, nor on
the ventilation apertures in the motor housing.
Notes on cleaning:
Before taking a break and after finishing work, clean the
concrete mixer inside and out.
Do not pound on the mixing drum with hard objects
(hammer, shovel, etc.). A dented mixing drum impairs mixing
operations and is difficult to clean, besides.
To clean the inside of the drum, put in some water and a few
shovels full of gravel and set the drum to revolving.
Remove any concrete or mortar left sticking to the teeth of
the axle-drive bevel gear or the crown gear segments
immediately.
Maintenance
The concrete mixer requires practically no maintenance.
The mixing drum and drive shaft are bedded on ball bearings with
permanent lubrication.
Never grease the ring gear!
To preserve the value of the mixer and increase its service life,
handle it as described in "Transport and storage". Furthermore,
the concrete mixer should be checked regularly for signs of wear
and tear or functional deficiencies. This applies especially to
moving parts, screw connections, protective devices and
electrical parts.
Repair
Pull plug each time before doing repair work.
Switch off machine and pull plug if repair work should be
necessary. Do not start machine during repair work.
Protective devices removed for repairs must be properly
remounted before starting the machine.
Only the manufacturer or companies authorised by the
manufacturer may perform repair work on electrical parts or
on parts which affect the space needed to mount electrical
equipment.
Use only unaltered original spare parts. Otherwise, the
manufacturer will assume no liability.
Adjust tooth play (if possible) see P. 24.
