guaranteed by the presence of the CE marking and by the Declaration of Conformity of the
producer of the machine with the built-in pump.
v
Before commissioning the machine, carefully read the indications of this manual and the
instructions of the machine with the built-in pump. In particular, make sure that you have well
understood the operation of the pump and of the machine with the built-in pump as far as the
fluid sensing operations are concerned.
v
Carry out the preliminary checks recommended by the producer of the machine with the built-
in pump.
v
Check that all delivery pipes are closed or connected to users in closed position (for instance
water gun)
v
Make sure that the pump moving parts are suitable protected and that they cannot be accessed
by unauthorised personnel.
v
Do not use the pump in case:
the pump has undergone strong hurts;
there are gas oil leaks;
there are visible water leaks.
In these cases have the pump be checked by a
Skilled Engineer
.
v
Have a
Specialised Engineer
make the scheduled checks as per the extraordinary
maintenance.
WARNING
v
In case of use at very low temperatures, make sure that there is no ice inside the pump.
v
Carry out the scheduled checks of the ordinary maintenance with special reference to the ones
relating to oil.
b)
Replace the oil plug without vent (17) with the oil plug with vent (8). This operation could
have already been carried out by the Producer of the machine with the built-in pump.
c)
With pump at a standstill, check that the oil level corresponds to the middle of the oil level
light (10). The oil level can be also checked (apart from the AX models) by unscrewing the
plug with vent (8): the correct level must be included between the two notches on the rod.
Remember that the oil level must be always checked with pump at a standstill and completely
cooled down.
For possible filling, refer to the types of lubricants reported in the paragraph “
FEATURES
AND TECHNICAL DATA
”.
d)
By referring to the use and maintenance manual of the machine with the built-in pump, check
the cleaning of the suction filter.
