8. MAINTENANCE
page 9
Before carrying out any maintenance operations, stop the machine and disconnect it
from the power supply.
1) Regularly check the oil level of the parts that require lubrication, (transmission pipes
and gear units). Replace the oil after the first 50 hours of operation and again after
1500 hours of operation (800 hours for the HD unit) or every year (use
ISO VG150
oil).
2) Every 50 hours of operation, grease the rotating parts (lubricators, piston articulated
joints, toothed wheels, etc.).
3) Wash the machine after use to prevent the residual sewage from generating natural
gas (explosion risk) and to prevent corrosion damage.
4) Regularly check the state of wear of the blade and the rotor. If necessary, replace
them.
Contact DODA authorised dealers directly for all spare parts.
For pumps with the "IV" unit, it is recommended that the oil be replaced
after every 500 hours of operation.
Oil should be introduced into both the bell housing and the gearbox.
Warning!! If not enough oil is introduced, it will remain in the bell hous-
ing and the gearbox will not be properly lubricated.
WARNING!
To properly replace the oil in the "IV" unit, carefully follow the instruc-
tions on pages 10 and 11.
