For routine maintenance of the diesel engine or
electric motor, follow the instructions in the manuals
provided.
Pumping units with diesel engine
During maintenance, ensure that
no metal or other conducting
object can short-circuit the
battery terminals with
consequent danger of explosion
of the battery.
If you have to isolate the battery,
first disconnect the negative pole
and then the positive pole (the
negative pole is earthed and if the
positive pole is disconnected
first, it increases the risk of
accidental short-circuit).
Pumping units with electric motor
During maintenance of the
pumping unit, isolate it by
disconnecting the socket from
the plug placed on the control
panel.
Inspection (version with oil vacuum
pump)
- Drain the condensate in the oil tank (Tab. 4,
part.10), through the cock at least once a day.
- For the suction pump use SAE 15W40 ENGINE
OIL.
- Every 1000 working hours wash oil suction filter
with gas/fuel oil (Tab. 4, part.11).
- Every 1000 working hours replace oil filter (Tab. 4,
part.12)
- Every 1000 working hours replace air filter (Tab. 4,
part.13)
Before starting work on the
pump make sure that it
cannot be started, even
accidentally.
