WARNING: Unexpected machine movement may cause
a serious accident. After stopping the machine, be sure
to stop the engine or apply the parking brake. Do not
only rely on the forward/reverse lever in neutral.
WARNING: Before changing oil, install lock bar (4) to
securely hold the front and rear frames to avoid the
occurrence of an accident due to unexpected machine
movement.
IMPORTANT: Do not use transmission oils other than
those listed in the "Brand Names of Recom-
mended Transmission Oil"
NOTE: Be sure to replace the transmission oil filter when
changing the transmission oil at the same time.
1. Operate the machine until the transmission oil is heated
to the appropriate temperature.
2. Park the machine on solid level ground. Lower the bucket
to the ground.
3. Move forward/reverse lever (1) to neutral. Press neutral
lever lock (2) to the LOCK position.
4. Apply parking brake (3).
5. Install articulation lock bar (4) to the front and rear frames.
IMPORTANT: The machine is equipped with a turbocharged
engine. Perform cool down operation before
stopping the engine. Failure to do so may
cause the lubricant on the turbocharger bear-
ing surfaces to desiccate due to the intense
heat present inside the turbocharger, possi-
bly causing damage to the turbocharger.
6. Turn the key switch OFF to stop the engine. Leave the ma-
chine untouched for 10 minutes.
7. Prepare a container of more than 50 L capacity to receive
the drain oil.
NOTE: The drain plug is magnetized. If excessive amount of
metal pieces are found adhered to the drain plug, con-
tact your nearest HITACHI dealer.
8. Remove drain plug (5) from the transmission bottom to
drain the oil. Dispose of the drain oil in the proper way.
