Checking the oil level
To use the pump in optimum conditions, the oil level must be observed and checked
regularly. This level is checked with the pump switched off, hot and on a horizontal
plane.
Note: Optimum pump performance and service life are obtained when the oil level is
between the maximum level and the minimum level.

If necessary, carry out the special preparation
procedure for the pump (see page 41), then:
- remove the filling cap (A).
- fill with oil until:
- the oil is between the maximum and
minimum levels (SD, C2 Series),
- the oil reaches the middle of the sight
glass (C1 Series).
This operation must be performed with
the pump switched off.
At the first start-up, to facilitate lubrication of the pump, pour a few drops of oil (1 to
2 cm
3
) through the inlet orifice.
C2 series: if the pump is equipped with an oil temperature sensor, the installation must
be made with the pump drained of oil.
