MACHINE OPERATIONS AND CONTROLS
1)
Remove the screws (1) and remove the cover (2).
2)
Loosen the cap of oil filler port (F) gradually to release
the internal pressure.
3)
Remove the cap of oil filler port (F).
4)
Add oil through the oil filler port (F) until the oil level comes between the levels H and L of sight gauge
(G).
NOTICE
Do not add oil above mark H. This could damage
the hydraulic system and cause oil spillage.
If the oil has been filled past level H. Wait for the
oil to cool down sufficiently, then drain the excess
oil through valve (P). For details, see MAINTE-
NANCE "METHOD FOR DRAINING THE HYDRAUL-
IC OIL TANK".
REMARK
The oil level will vary depending upon the oil tempera-
ture. Depending on the temperature, refer to the fol-
lowing guidelines:
• Before starting the operation: Around L level
(Oil temperature 10 to 30 °C)
• Normal operation: Around H Level
(Oil temperature 50 to 80 °C)
5)
Install the cover (2) and tighten the screws (1).
METHOD FOR CHECKING COOLANT LEVEL, ADDING COOLANT
• Do not open the radiator cap unless it is necessary. When checking the coolant, check it with the
reservoir tank when the engine is cold.
• Immediately after the engine is stopped, the coolant is still hot and the pressure is accumulated in
the radiator. There is a risk of severe burns if the cap is removed in these conditions to check the
coolant level. Always wait for the temperature to decrease, turn the cap slowly to release the pres-
sure, then remove the cap with care.
1.
Open the cover (1)
2.
Check the reservoir tank (2).
If the coolant level is within the range between FULL and
LOW, the coolant amount is at a proper level.
3.
If the coolant level is LOW, proceed as follows.
