 : Shorten the interval in a dusty work site.
 : Maintenance required only during first time.
* : 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 Hitachi Long-Life
Coolant 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.
