Niro Soavi S.p.A
The intake filter housed inside the oil tank does not have a built-in by-pass. If
the filter clogs up the pressare drop through the filter will increase leading to
cavitation of the gear pump and pressure switch action. Cleaning frequency is
given in the “Table of Periodical Maintenance”, Chapter 4.2.
To clean the metal mesh intake filter (figure 4.9.1, item B):
−
remove the oil tank as previously explained
−
disconnect the tank (A) from the body (C) by loosening the retaining screws
and removing the filter (B) from the tank
−
unscrew the filter (B) off the end of the suction pipe
−
put it in a container with petrol or solvent for about 30 minutes;
−
clean it with compressed air blown opposite to the filtering direction (i.e. from
the inside towards the outside).
WARNING: Carry out the operations with utmost caution, wearing suitable
protection for the body and the eyes against any petrol splashes; wear a
filtering mask and do not inhale the vapour; if there is any contact with the
eyes, wash abundantly with water and consult a doctor.
OIL COOLER MAINTENANCE
The machine is equipped with a water / oil cooler which is not requiring usually
any maintenance. In case of use of hard water, it is possible to have problems
with clogging of the cooler because of calcium carbonates deposits, which is
reducing the heat transfer efficiency.
It is therefore necessary to replace the oil cooler if it is not able to reduce
anymore the oil temperature (usually the temperature difference between oil
inlet and outlet is in the range of 5 to 10 °C); in case the oil cooler is made of
stainless steel (optional) it is possible to clean it with suitable cleaning solution
to scale the tubing.
