CHAPTER 2
SAFETY INFORMATION
2.1
GENERAL SAFETY STANDARDS
The use, lifting, installation, maintenance and scrapping of the machine are allowed only to
qualified staff. Qualified staffs are composed by people who are authorised by the safety responsible
to do any activities due to their experience and acknowledgement of the operating of the machine and
of the standards, rules and actions.
The user must be carefully taught about the operating of the machine to avoid any misuse of it and
about the safety devices, which the machine could be eventually equipped with. The safety devices
will have to be kept always assembled and to be daily checked.
The manufacturer offers training and assumes no liability for any damages due to a misuse of the
machine by an unskilled staff.
The manufacturer recommends following carefully the instructions and procedures of the operating
manual and the safety standards concerning the safety devices and the general rules of the work
environment.
Verify the accordance of the machine to the standards in force in the State where the machine has to
be installed.
The operating manual must be carefully read by the safety responsible, by the operators and
maintenance engineers. It must always be kept near the machine in order to be able to read it any
times it will be necessary.
Any tampering or modifications of the machine (electric, mechanical etc.) that are not allowed by a
written agreement of the manufacturer must be considered as not permitted and the manufacturer will
not accept to be charged for any damages.
The removal or the tampering of the safety devices will be an infringement to the EEC Safety
Standards. The manufacturer assumes no liability for any damages.
The machine has to be installed in places safe from fire and explosions.
We do recommend using only original spare parts and accessories; on the contrary the manufacturer
assumes no liability.
Be careful that any dangerous situations won’t happen during the working; stop immediately the
machine in the event that it will not work properly and ask the manufacturer or the Authorised Service
Staff of the dealer at once.
The manufacturer assumes no liability for any damages to people, things and animals caused by the
non-compliance of the above instructions.
2.2
SAFETY DEVICES
MEANING: Safety devices are all the safety measures, which consist of the use of specific technical
equipment (guards, cages etc.) to protect the operator from any danger that couldn’t be avoided during
the planning.
FIX AND MOVABLE SAFETY DEVICES
The Mixer is supplied in two versions:
CE VERSION: The mixer E095 has got a protection door (B16), which prevents the opening during the
test so that the operator cannot come in touch either with the internal mechanisms or with the beater
(B1/C1). The door opening causes an immediate interruption of the power feeding; in this way the motor
(B4/C4) and the beater stop moving. The rotation can start again only after the closing of the protection
door.
ATTENTION
It is suggested to open the protection door only when the mixer is not turning, the
opening of the safety door during the working of the appliance must be made only in
case of real and urgent need.
STANDARD VERSION: For the Mixer E094 no safety devices are foreseen.
ACTIVE SAFETY DEVICES
Active Safety Devices are all those disposals and devices, which cancel or greatly reduce the risks to the
operator. They require a conscious and active behaviour of the operator to be activated.
In every appliance there’s a main switch (B13/C13) acting also as emergency switch.
By activating it, the feeding to the mixer is disconnected and therefore also the beater (B1/C1) stops
moving.

BEATER POSITIONING
The automatic mortar mixer is furnished complete of tang for the beater attack. In order to place correctly
the beater proceed in the following way:
1. If this was not already opened, open the safety door (B16) and remove the bowl if it’s in the mixer
housing.
2. Unthread the tang (B12/C12) of the rotation pin (B6).
3. Fix the beater (B14/C14) to the tang (B12/C12), inserting two fins set on the beater in the special
joints present on the tang (see picture 1 of the enclosure D)
4. Screw the tang to the beater through the special screw.
5. Take the beater (B1 4/C14) and couple it with the pin (B6/C6) as shown in the picture 2.
6. Push the beater upwards till the small plug that is on the pin (B6/C6) touches its seat that is on the
beater connection (see detail 2 of picture 3).
7. At this step, turn the beater counter clockwise until the rotation stops, and then release the beater (see
detail 3 of picture 3); the spring (B8/C8) will automatically block it in the right position.
8. Fix the beater, the tang and the rotation pin through the fixing screw.
BOWL POSITIONING
Before placing the bowl (B14 /C14) inside the mixer housing, ensure to have correctly filled the same
