MACHINE OPERATIONS AND CONTROLS
METHOD FOR CHECKING OIL LEVEL IN HYDRAULIC TANK, ADDING OIL
• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-
jury. Accordingly, wait until they have cooled down before starting the work.
• When removing the oil filler cap, the oil may spurt out. Turn it slowly to release the internal pres-
sure, then remove it carefully.
1.
Set the machine in the posture shown in the figure.
If the machine is not set as shown in the figure, set it ac-
cording to the following procedure.
1)
Start the engine, and run it at low speed.
2)
Retract the arm and bucket cylinder rods to the end.
3)
Lower the boom to lower the bucket tooth to the
ground.
4)
Stop the engine.
2.
Turn the staring switch key to ON position within 15 sec-
onds after stopping the engine, and move each control lev-
er (for work equipment and travel) to the full stroke in all directions.
The internal pressure is released by this operation.
3.
Stop the engine.
4.
Open the door on the left side of the machine and check
sight gauge (G).
When the oil level is between the lines H and L, it is appro-
priate.
If the oil level is below level L, the hydraulic oil is insuffi-
cient. Perform the following procedure.
5.
Add oil through oil filler port (F) until the oil level comes between levels H and L of sight gauge (G).
NOTICE
Do not add oil above H line. It may damage the oil cir-
cuit and cause the oil to spurt out.
If oil has been refilled exceeding H level, swing the up-
per structure until drain plug (P) beneath the hydraulic
tank comes between the right and left tracks. Stop the
engine. After the hydraulic oil has been cooled down,
remove cover (1) and drain the excess oil through
drain plug (P) to the container for receiving the oil.
