Care and maintenance
The only scheduled maintenance of the 313F, 313S and 313U is to inspect the motor brushes and to replace them before
their length is less than 6mm 1/4". The life of the brushes will depend on the duty of the pump, which is expected to be
at least 7,500 hours at maximum speed. When the pump needs cleaning, remove the pumphead and use a mild solution
of detergent in water. Do not use strong solvents.
If the gearbox is dismantled, it should be filled with a good quality grease such as Castrol MS3.
