5.1 GENERAL PROVISIONS

- Check there is oil in the pump, by looking at the oil indicator on the
rear cover;
- Make sure the pipes are not clogged and are free from waste;

no reason whatsoever must the pump work dry – this is to avoid
burning the pressure seals;

correctly: joint covers, mechanical seal protections, electric motor fan
cover, etc.;
