10 Commissioning Procedure
All Planetary drive units listed in this manual use ISO EP 320 (mineral oil) gearbox oil for operating in
tropical ambient temperatures. See maintenance section of this manual for gearbox oil volume, gearbox oil
volume checking as well as the gearbox oil recommended for cold climate conditions. The gearbox oil quantity is
also engraved on the serial tag located between the ears of the hood.
To ensure best motor life, run motor for approximate one hour at 30% of rated pressure before application to full
load. Be sure that motor and gearbox are full of uids prior to any load application. When procuring any hose
assemblies for use on your Digga Planetary drive unit ensure that the maximum operating pressure of the hoses
is always 25% higher than what the excavator or machine can produce (which the planetary drive unit will be
used on).
If required, ensure that the case drain hose is connected to the reservoir of the machine. It is
important that the pressure in the case drain hose is not reading more than 690kPa (100PSI), whilst
operating and that a consistent trickle of hydraulic oil is being returned to the excavator reservoir.
Intermittent and spurts of ow from the case drain hose are not standard design symptoms. If this
occurs, please consult a Digga Dealer or Digga Head Oce.
