OPERATION
6.
Add oil through oil filler port (F) of the hydraulic tank 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.
REMARK
The oil level varies with the oil temperature. Use the fol-
lowing as a guide for check.

Before starting operation: Between H and L levels
(Oil temperature 10 to 30 °C)
•
Normal operation: Around H Level
(Oil temperature 50 to 80 °C)
