II.4 TRANSPORT - HANDLING AND STORAGE
DANGER!
The unit must be transported and handled by
skilled personnel trained to carry out this type of
work.

Dispose of the packaging materials in compliance
with the national or local legislation in force in your
country.
The EWMIG 236÷260 models are supplied:
 covered with nylon shrink-wrap.
Each unit is supplied complete with:
 User instructions;
 Electronic control manual;
 Wiring diagram;
 List of authorised service centres;
 Warranty document;
 Use and maintenance manual for the pumps, fans and safety valves.
II.4.2 LIFTING AND HANDLING
DANGER!
Movement of the unit must be performed with care,
in order to avoid damage to the external structure
and to the internal mechanical and electrical
components. Also make sure that there are no
obstacles or people along the route, in order to
prevent the risk of impact, crushing or tipping the
lifting and handling device.
Use a fork-lift or pallet truck to move the machine with its packaging
intact to the final installation position.
Pass the straps through the slots on the base of the unit, having first
checked their suitability (their strength and the state of wear and tear).
Take the strain on the slings, checking that they remain properly
attached to the lifting-hook; lift the unit a few centimetres, then, only
after checking the stability of the load, carefully carry the unit to the
installation site.
