- IMER COMPRESSOR (Page2 Ref. 6)
The air delivered by the compressor to the spray jet via a rubber
hose is used to spray the pumped material. Compressors with
different air flow rates can be applied on the machine: from 250
l/min on the single phase version to 310 l/min on the 3-phase
version of air output...
Maintenance: Check the air filters weekly, clean or replace when
necessary, above all if working in excessively dusty
environments.
On the 3-phase version check the oil level daily: recommended
oil type superdiesel multigrade 15W40 (code imer 3225358)

5. OPERATION SAFETY

- Before using the plastering machine, ensure that it
is fitted with all safety devices.
- Never insert parts of the body and/or tools in the
hopper .
All current standards governing accident prevention and safety
devices must be observed in the workplace.
There must be a clearance left around the machine of at least
one metre, left completely free and with a smooth walking sur-
face where only the operator assigned to the machine may
stand.
Take care when handling bags of material, to avoid sprays which
may come into contact with the eyes or other parts of the body.
Wear safety goggles and gloves. Avoid the dispersion of dust
which may be inhaled. Always wear a mouth and nose protection
mask during use.
- Never use the machine in environments subject to the
risk of explosions, fire or underground.
The plastering machine is not equipped with a lighting system
and therefore the workplace must be fitted with adequate light-
ing.
The power lines must be laid to prevent any possible damage.
Never place the plastering machine on electric power cables.
Ensure that the electrical connection is protected against the risk
of water penetration in connectors. Use exclusively connectors
and couplings equipped with water spray protection.
- Never use inadequate or provisional electric lines: these must
be laid exclusively by specialised personnel
- Repairs to the electrical circuit must be performed exclusively
by specialised personnel. Disconnect the machine from the power
supply before performing maintenance or repairs.
-Avoid contact of electric wires with movable and/or moving
parts of the machine to avoid injury from contact with live metal
parts.

6. ELECTRICAL SAFETY

The plastering machine STEP120 is constructed according to stan-
dard CEI 44-5, with protection against water sprays and protection
against overload and power failure.
The plastering machine must be connected to the earthing circuit.

7. MECHANICAL SAFETY

The hazardous points on the STEP 120 are protected by means
of suitable safety devices, which must remain fitted at all times
and kept in perfect condition, such as the electric motor cooling
fan guard, the grid on the mixer, the vibrating screen and the
hopper grid to prevent contact with the mixer. When these devices
are disengaged, all moving parts of the machine are shut down
fore machine start-up.
8. TRANSPORTABILITY (fig.3), LIFTING (fig.4),
TOWABILITY (optional fig.5)
always detach the power plug.
- detach the water delivery hose and material delivery line
- remove, if fitted, the remote control.
-Check that the vibrating screen is suitable secured with the
valpa closure.
Only a minimal amount of the material should be in the hopper
when handling.
Move the machine by means of the specific handle.
