Place the containers to catch the oil under the drain plug
(P) for the swing machinery at the bottom of the machine,
and under the drain plug (Q) for the electric swing motor.

Loosen the drain plug (P) for the swing machinery at the
bottom of the machine and the drain plug (Q) for the elec-

problem to stop the draining operation.
• To reduce the oil draining time, swing the upper struc-
ture to increase the oil temperature slightly, then drain
the oil. Never swing the upper structure while draining
the oil. This may cause breakage of the swing machi-
nery.
