MAINTENANCE INSTRUCTIONS 

Table of lubricants 

The pump is delivered complete with  high-performance 

30

 weight, non-detergent oil  suitable for the 

intended ambient conditions (see "Environmental operating limits"). 

Inspecting the pump mounting 

Check that the pump's fixing screws have not become loose. 

If necessary, tighten them with the driving torque stated in the installation design. 

Inspecting the connections and pipes 

- Inspect the connections for leaks.

Leaks can normally be dealt with by tightening the connections properly. 

If leaks from the intake pipeline connections are noticed, the seals must be repaired. 

- Inspect the hoses.

If the pipes show signs of aging, breakage, swelling, rubbing, etc., they must be replaced. 

Inspecting the Filter 

- Inspect the filter cartridge.

If the cartridge is fouled, wash it thoroughly to remove the dirt.

If the cartridge is torn or cracked, it must be replaced.

Checking the oil level 

- Check  the  oil  with  the  pump  level,  ensuring

that it has been running for at least 5 minutes in
normal working conditions.

-

If the oil level is not between the MIN and MAX

marks on the tank, add or remove oil to restore
this level and check, still with the pump running,
that the oil level does not vary so much that it
leaks from or is no longer visible in the tank.
