Maintenance
5.3 Check the oil level
Note: If required, the oil level can be checked while the pump is operating, however switch off the pump and
isolate the pump and other components in the pumping system from the electrical supply before pouring
oil into the pump.
1. Check that the oil level is in the middle of the sight glass (Figure 10, item 1).
2. If the oil level is below the middle of the sight glass, remove the oil filler plug (Figures 1, 2, and 3, item 2) and
pour more oil into the reservoir until the oil reaches the middle of the sight glass. If the oil level goes above the
middle of the sight glass, open the oil drain tap (Figures 1, 2, and 3, item 8) and drain the excess oil from the
pump.
3. Refit the oil filler plug.
4. If the oil is contaminated, drain and refill the pump with clean oil as described in Section 5.4. Change the oil if
the colour is mid-brown.
