SLEWING GEARBOX - OIL CHANGE
DRAINING HOSE FOR OIL CHANGE
The gearbox is equipped with a special sleeve (1)
for oil discharge.
In this way the oil change can be performed in a
clean and not polluting way.
Perform the oil change in this way:
- place under the drain sleeve a collecting container
for old oil;
- take from the equipment available the relevant
draining hose;
- unscrew the blanking plug (3) from the oil drain
sleeve (1);
- screw up the hose (2). The sleeve (1) opens auto-
matically and oil is discharged;
- once oil has been drained, unscrew the hose (2).
The drain sleeve (1) closes independently;
- retighten the protection cover (3).
OIL CHANGE
Prepare a collecting container for used oil.
The oil drain sleeve (1) is accessible from the bot-
tom though an opening on the upper structure.
Unscrew cover (4) of the expansion tank (5).
Unscrew the blanking plug (3) from drain sleeve (1).
Drain oil through the drain hose (2).
Raise the oil drain hose on the travel gearbox.
Fill in the new oil through the drain hose, until the
level inside of the expansion tank reaches an height
of about 1-2 cm (0.39-0.79 in).
Unscrew the oil drain hose.
Screw up the cover (4) of the expansion tank (5).
