PART NUMBER: DE-000127
CAUTION
10 Commissioning Procedure
Before the drive unit is even connected to the machine ensure that it is full of hydraulic oil and the gearbox is full of gear oil.
For details, see the Maintenance section of this manual.
CAUTION
All Digga Planetary drive units are despatched from the factory full of uids (hydraulic and gearbox oil) unless a
warning decal is attached. The decal is only applied in special circumstances, for example if a drive unit needs
to be air-freighted to the customer. Air transportation regulation prohibits certain uids from being air-freighted.
If there are no uids in the drive unit at the time of despatching, then the decal DE-000127 will be applied to the
drive unit.
• Once you have determined if the drive unit has gearbox oil in or requires oil, ensure that the correct grade
and quantity of oil is used. Do not run the drive unit without gearbox oil. Connect the hydraulic hoses
and if required, optional 2 Speed electrical harness to the machine. If the customer has ordered the
optional Pressure di󰀨erential kit and the Diggalign kit, then there will be 2 additional electrical harnesses
to connect.
• 2 Speed drives tted with an Eaton VIS motor require a case drain. The case drain hose is already tted
to the hydraulic motor and needs to be connected to the hydraulic line which returns to the hydraulic tank
of the excavator.
