4. INSTALLATION AND USE
4.1 ASSEMBLY OF FRAME AND DRUM ref. Fig.3 (1-2-3-4-5-6)
The IMER mixer arrives completely dismantled in a box.
-Remove all the machine components from inside the mixing drum.
Fig. 3-1) Bolt the tilting levers (ref.1) to the frame (ref. 2) with the
nuts (ref. 3) and bolts (ref. 4), using the washers (ref. 5).
Fit the wheels (ref. 6) with the split pins (ref. 7).
Fig. 3-2) Fit the motor reducer (ref. 1) to the frame (ref. 2) with the
nuts. In electric motor versions, bolt on the motor guard (ref. 4) with
the bolts.
Fig.3-3) Align the centre bush of the drum with the motor reducer
shaft (or the reduction gear shaft in internal combustion engine
versions).
Warning. The slot in the drum bush must fit over the
pin on the motor reducer shaft.
Place the washer (ref. 2) in position and fully tighten the bolt (ref. 1).
Fig. 3-4) Position the paddles inside the drum and secure them
in position with the nuts and bolts (use a 19 mm spanner ).
The electric motor version cement mixer is now ready for use.
Fig. 3-5) Assemble the stand and fit to the mixer.
- Make sure the axle securing clip is engaged before
lifting or lowering the mixer.
4.2 TRANSPORT
Warning. Always disconnect the mixer from the power
supply before moving it.
To transport the machine, hold the tipping handles (ref.1) and
move as shown in Fig. 4.
4.3 INSTALLATION
- Position the machine on a firm level base (maximum
allowable slope 5°, as shown in fig.5) to avoid it sinking
into the ground or tipping over during operation.
- Warning.
If the machine is supported on its wheels and/or stand,
ensure that accident prevention regulations are complied
with. The mixer must not tip over.
4.4 ELECTRICAL CONNECTION
- Check that the power supply voltage and frequency
are as stated on the electric motor data plate.
The electric motor version mixer must be connected to the power
supply (110/230 V) with a three-core rubber insulated cable, type H
07RN-F, with each wire having a minimum cross- section of 1.5 mm².
The cable must not be longer than 50 m.
- Ensure that the power supply line is fitted with a
residual current protection device upstream.
- The IMER mixer can only function if all the safety
devices with which it is equipped are in perfect condition.
- The mixer must not be used if the power connection
is defective.
- The power connection lines on the work site must be
installed so that they cannot be damaged and that water
cannot enter the connections. Only use connectors fitted
with protection against water spray. Do not install the
mixer on top of electricity cables.
- Do not connect the mixer to temporary connections.
If necessary consult specialised personnel.
Ensure that the power supply cable is properly connected to the
plug on the mixer and that the connector retaining ring is tightened.
4.5 STARTING ELECTRIC MOTOR VERSIONS
Switch on the mixer at the switch on the motor reducer control panel.
If the mixer drum movement is blocked the motor thermal circuit-breaker
trips and breaks the electric circuit. The mixer can be re-started by
switching it on again.
4.7 USE
-Do not allow other people to remain in the vicinity of the machine
whilst working.
-Do not use the machine in a fire-risk zone and/or underground.
-Always switch off the motor/engine before moving and/or
unloading the machine.
- Check that the paddles and drum rotate in an anti-
clockwise direction when viewed from the mouth of the
drum itself.
Connect the machine to the power supply and start it up (see
point 4.5).
Check if the rounds of the drum is 25 r.p.m.
Gradually introduce water, cement and aggregate. When the mix
has reached the required quality, position a suitable container
under the mixing drum and, while the drum is still rotating,
discharge the mix by operating the tipping levers.
- Keep a firm grip on the two tilting handles when
emptying the drum.
The ROLLBETA mixer drum has two fixed positions, one for
mixing (mouth of the drum up) and a discharge position (mouth of
the drum down).
All drum movement operations are controlled by the two tipping
levers.
- The mixing drum must not be interfered with during
rotation.
