• The ring nut
(
K2
)
must be tightened all the way.
Every 100 working hours, with the pressure at 0 bar, check
that it is tightened all the way.
• The supplied pin
(
K3
– ref. 20144)
also serves the purpose
of closing and opening the pump unit’s locking ring-nut
(K
4
).
This ring nut must always be closed in order to act as
a locking counter-nut.
CHECKING THE HEAT EXCHANGE RADIATOR
Always keep the heat exchange radiator
(
K5
)
on the electronic
control box clean, in order to guarantee correct heat exchange
with the ambient air.
We suggest cleaning using a jet of compressed air.
PRESSURE SWITCH SEAL CHECK
Check that no material is escaping from the safety hole
(
K6
)
at
the bottom of the protective container.
If necessary, replace the O-Ring for the pressure sensor
(
K7
).
