Before servicing the unit:

Press the stop button on the motor protector switch, lock out the start up button,
close the protective lid and remove the keys.
-
Isolate the unit from electrical power sources making sure that no one can restore
power; to this purpose, insert the padlocks and all other required devices on the
power line.
-
Use signs or other appropriate means to indicate that maintenance is being done on
the unit.
-
Wear proper protective clothing such as gloves, safety shoes, etc. while maintenance
is being done.
·
To prevent injuries to persons or damage to things, unit maintenance must be
done by specialised personnel in compliance with safety procedures.
·
Before using the nuts and bolts, make sure they are in perfect condition,
otherwise replace them with new components that are identical to the original
ones. Self-locking nuts must always be replaced with new components.
