MACHINE OPERATIONS AND CONTROLS
METHOD FOR CHECKING COOLANT LEVEL, ADDING COOLANT
• Do not open the radiator cap unless necessary. When checking the coolant level, check the reser-
voir tank when the engine is cold.
• Do not remove the reservoir tank cap while the radiator coolant temperature is high. Boiling coolant
may spurt out. After the coolant temperature goes down, turn the cap slowly to release the pres-
sure, then remove it.
1.
Open the hydraulic tank inspection cover on the left side of the machine.
2.
Check that the coolant level is between FULL and LOW
marks of reservoir tank (1).
• When the coolant level is between FULL and LOW
marks
The coolant level is proper.
• When the coolant level is below LOW mark
The coolant is insufficient. Add coolant to FULL level
through the filler port of reservoir tank (1).
REMARK
The coolant may overflow from the reservoir tank
drain hose. This is no problem. It occurs because too
much coolant has been added.
After adding, tighten the cap securely.
3.
Check reservoir tank (1) for abnormality.
If reservoir tank (1) is empty, leakage of coolant should be
suspected.
4.
If reservoir tank (1) has abnormality, repair it immediately.
5.
Check the coolant level in the radiator.
6.
If the coolant level is low, add Non-Amine Engine Coolant
(AF-NAC) of the same density in radiator according to the
Non-Amine Engine Coolant (AF-NAC) density table in "METHOD FOR USING FUEL, COOLANT AND LU-
BRICANTS ACCORDING TO AMBIENT TEMPERATURE" then add Non-Amine Engine Coolant (AF-NAC)
to the reservoir tank (1).
7.
After adding, close the hydraulic tank inspection cover.
