Start up
During and immediately after the pump start up, any hydraulic system must be closely and frequently
checked.
1. To assure best pump performance, run the pump for approximately one hour at 30% of rated
pressure and speed before running at full load.
When running make sure the pump and oil temperature and noise level are sufficiently low. High
temperature or noise level might be symptoms of unforeseen operation conditions that have to be
analyzed and cleared.
2. Check for system leakage and make sure the system is operating satisfactorily.
3. To ensure that the contamination in the hydraulic system does not damage the pump; the following
procedure is recommended after a brief period in operation:
a) After a brief period in operation, have a hydraulic fluid specimen analyzed for the required
cleanliness level.
b) Replace oil filter or change the hydraulic fluid if the required cleanliness level is not reached.
Operational checks
The product is a component which requires no settings or changes during operation.
The machine/system manufacturer is responsible for the proper project planning of the hydraulic system
and its control.
Danfoss recommends ongoing tests for optimal pump performance.
1. Regularly verify that the temperature of the ambient and the operating oil are those initially
determined.
2. Do not subject the pump to pressure, pressure drop or speeds exceeding the maximum values stated
in the appropriate catalogs.
3. Filter the oil to maintain the grade of contamination at 22/20/16 (ISO 4406-1999) or better.

Warning
If maintenance has to be performed in an explosive and hazardous atmosphere, an anti-sparking safety
tool must be used.
