PREPARATION OF THE MIXER TO WORK AND THE WORK PROCEDURE
While preparing the concrete mixer for work, it is necessary to check tightening of threaded connections, operability
of an electrical wiring, the start-up equipment. Ensure the operability of the mixer, test the idle operation of the
mixer and only after that begin working with loading. When installing the concrete mixer at the site, it is necessary to
maintain the minimum distances of the working site ensuring safe and productive functioning. It is strictly forbidden
to encumber the working site. Keep a safe distance around the concrete mixer.

The mixer operates in cycles with the following sequence: loading, mixing, unloading. The mixer should be installed
on a plain and solid horizontal surface. It is recommended to turn on the mixer with the drum in a vertical position.
ATTENTION!
Perform loading and unloading only when the drum revolves to prevent the motor overload.
Do not start the concrete mixer with the loaded drum!
Loading of the drum according to the compounding is made manually. At preparation of concrete mix it is necessary
to pour in a portion of water, then to pour cement and consistently add gravel, sand and the rest of water. An optimum
angle of the horizontal inclination of the drum during mixing should be about 35 ° for concrete and 20 ° for mortar.
Load the material on the blade only against the direction of its rotation.
Do not overload the concrete mixer. The overload can cause the breakdown of equipment. Time of mixing is about 120 sec.
Unloading of the ready mix is made with a revolving drum by inclining it with its port facing down. After mix unloading the
drum is set to the loading position and the cycle is repeated. The recommended load of the concrete mixer should make at
most 75%/hour of an operating time: work with this loading prolongs the concrete mixer lifecycle.
ATTENTION!
It is strictly forbidden to lubricate the pair: gear wheel − toothed rim for prevention of premature
wear of the gear wheel and the toothed rim.
Reduce risk of inadvertent start. Make sure that the switch is in the "OFF" position before connection of the power
cable to the mains. At interruption in electric power supply turn the switch to the "OFF" position.
It is forbidden to be in a close proximity of the machine. Serious harm to health is possible in case of turning over of
the machine or accidental contact with the cutting parts.
Do not leave the working machine unattended, turn the power o. Do not leave the machine unattended until it is
fully stopped. Other persons (except for the operator) should be at distance of not less than 2 m from the working
concrete mixer. Before a long working pause and upon termination of work it is necessary to clean the concrete mixer
inside and outside.
