Note 1: When preservation work of the environment is of importance, typically river construction
work, marine and sea shore work, forestry work and the like, use of biological hydraulic
oils and greases is recommended. For details of using them, contact us or our sales
service agency.
Note 2: On the coolant
(1) The coolant is required to perform important functions such as an anticorrosion agent as well
as an antifreezing agent for a cooling system.
Thus, use this coolant continuously even in areas where anti-freezing characteristic is not
required.
Use of any other coolants than our authorized coolant (LLC) is in principle not recommended.
Otherwise a serious failure may occur in the cooling system including the engine.
(2) For the mixing proportion of coolant and diluting water, refer to the descriptions under
"Maintenance 10.3 [4] Cleaning the Inside of Engine Cooling System".
On factory shipment, the coolant is added with our genuine coolant (LLC) at a proportion of
30% or more, there is no need alter the concentration unless below a temperature of -10°C.
If the temperature goes below -10°C, adjust the coolant concentration in accordance with the
proportion table given under "MAINTENANCE 10.3 IRREGULAR MAINTENANCE [4]
CLEANING ENGINE COOLING SYSTEM”.
(3) To maintain the anticorrosion performance of the coolant, always keep the concentration at
30% or higher.
