The case drain hose is already fitted to the hydraulic motor and needs to be connected to the hydraulic line which returns to the
hydraulic tank of the excavator.

OF RATED PRESSURE BEFORE APPLICATION TO FULL LOAD. BE SURE THAT MOTOR AND
GEARBOX ARE FULL OF FLUIDS PRIOR TO START UP.

UNIT ENSURE THAT THE MAX OPERATING PRESSURE OF THE HOSES IS ALWAYS HIGHER THAN
WHAT THE EXCAVATOR OR MACHINE (WHICH THE PLANETARY DRIVE UNIT WILL BE USED ON) CAN
PRODUCE.

CONNECTED TO THE RESERVOIR OF THE EXCAVATOR.
IT IS IMPORTANT THAT THE PRESSURE IN THE CASE

TRICKLE OF HYDRAULIC OIL IS BEING RETURNED TO
THE EXCAVATOR RESERVOIR. INTERMITTENT AND
SPURTS OF FLOW FROM THE CASE DRAIN HOSE

CONSULT A DIGGA DEALER OR DIGGA AUSTRALIA
SERVICE IF THIS OCCURS.
