Note 1: Engine oil
(1) Use engine oil equivalent to or better than the following standards and types.
• API service type CJ-4 or CK-4
• ACEA service type E-6
• JASO service type DH-2
(2) The machine is provided with SAE 10W-40 DH-2 oil when shipped from the factory.
(3) When replacing the oil with oil of a different grade, be sure to replace all of the oil and not mix different types.
Note 2: Coolant
(1) Coolant plays an important function in preventing corrosion in the cooling system, as well as in protecting
against freezing.
This coolant must therefore always be used even in areas where anti-freeze is not required.
Use of coolants other than long-life coolant (LLC) or extended-life coolant (ELC) is not recommended in
normal circumstances. Otherwise, there is a risk of serious failure in the cooling system, including the
engine.
(2) For details on coolant dilution ratio, refer to [1] Cooling water replacement in "6.17.9 MAINTENANCE
EVERY 2,000 HOURS" on P.6-70.
Always use soft water for diluting the coolant.
At the time of shipping, unless otherwise indicated, genuine coolant (LLC) is added at a ratio of at least 30 %
or more. There is therefore no need to alter the concentration unless temperatures are below -10 °C.
For temperatures below -10 °C, adjust the coolant concentration using the mixture chart in [1] Cooling water
replacement in "6.17.9 MAINTENANCE EVERY 2,000 HOURS" on P.6-70.
(3) To maintain the anti-corrosion performance of the coolant, always keep the concentration at 30 % to 60 % or
higher.
(4) Use coolant equivalent to or better than the following standards.
• ASTM D6210 or D4985
• JIS K-2234
• SAE J814C, J1941, J1034, or J2036
