:
Shorten the maintenance interval when the machine is operated in dusty areas.
:
Maintenance required only during first time check.
*:
When genuine Hitachi Long-Life Coolant (LLC) is used, change every two years or 2000 operating hours, whichever
comes first.
IMPORTANT:
Use soft water as a coolant. Do not use strong acid or alkaline water. Use the coolant with genuine Hitachi
Long-Life Coolant (LLC) mixed by 30 to 50 %. If a coolant mixed with less than 30 % of genuine Hitachi Long-
Life Coolant (LLC) is used, service life of the cooling parts may be shortened due to damage by freezing or
corrosion of coolant system parts.
If mineral-rich water is used for coolant, water stain or scale may build up inside the engine or radiator,
causing overheat due to deterioration of coolant performance.
