Dear customer,
congratulations on your choice of purchase: the IMER CON-
CRETE MIXER, the result of years of experience, is a very
reliable machine equipped with all the latest technical
innovations.
WORKING IN SAFETY
In order to be able to work in complete safety, the following
instructions must be read carefully.
This OPERATING AND MAINTENANCE manual must be kept on
site by the person responsible for the worksite, e.g. the site
foreman, and must always be available for consultation.
The manual should be considered as being an integral part of the
machine, and must be kept for future reference (EN 292/2) until
the machine itself is disposed of. If the manual becomes damaged
or lost, a replacement can be obtained from the manufacturer.
The manual contains important information regarding the site
preparation, installation, use of the machine, maintenance and
spare parts ordering. Nevertheless, the installer and user must
both have adequate experience and knowledge of the machine.
In order that the safety of the operator, safe working and long life
of the equipment can all be guaranteed, the instructions in this
manual must be followed together with safety standards and
health and safety at work laws currently in force (use of suitable
footwear and clothing, use of helmets, gloves and goggles, etc.).
- Always make sure that signs are legible
- It is strictly forbidden to carry out any form of
modification to the structure or working parts of the
machine.
IMER INTERNATIONAL decline any responsibility in the case of
non-compliance with laws and standards governing the use of
this equipment. In particular: improper use, defective power supply,
lack of maintenance, unauthorised modifications, partial or total
failure to comply with instructions contained in this manual.
IMER reserves the right to modify the characteristics of the con-
crete mixer and/or the contents of this manual without any
obligation to update previous machines or manuals.
1. TECHNICAL SPECIFICATIONS
Table 1 reports the technical specifications of the concrete mixer,
with reference to figure 1.
2. DESIGN STANDARDS
The concrete mixers have been designed and built in accordance
with the following standards: EN 292-1-2, EN 60204-1, prEN 12151.
3. NOISE EMISSION LEVEL
Table 2 indicates the noise level produced by the mixer, measured
at the operator’s ear (L
pA
at 1 m - 98/37CE) and the environmental
noise emission level (power L
WA
) measured in accordance with
EN ISO 3744 (2000/14/CE).
4. DESCRIPTION AND OPERATION
- The concrete mixer is designed for use on
construction sites, for preparing and mixing concrete,
mortars, cement mixes, etc.
- Use of the machine is unadvisable with temperatures
below 0° C.
CEMENT MIXER WITH ELECTRIC MOTOR (FIG. 1)
The cement mixer comprises a frame (ref. 1) with two hard wheels
(ref. 2), an arm (ref. 3) onto which the gear unit is attached (ref. 4),
driven by a poly-V belt (ref. 5) which is driven in turn by the electric
motor (ref. 6).
The mixing drum (ref. 7) is mounted on the gear unit: the drum bush is
fitted onto the gearbox’s tapered output shaft by inserting the pin into
the slot on the drum bush. The mixing drum is secured onto the gear
shaft using a screw.
Drum tilting is controlled by manual rotation of the handwheel (ref. 8),
which acts on the worm – wheel gear unit (ref. 9), connected to the
arm.
The electric motor is switched on and off using the two pushbuttons
on the electric control panel (ref. 10).
The electric control panel has a plug (ref. 11) for connection to power
supply.
To transport the concrete mixer on site (with drum empty) use the
steering gear (ref. 12) which can be extracted from the frame.
5. SAFETY INSTRUCTIONS
- Before using machine ensure all safety devices
