3. BEFORE YOU OPERATE ––––– 43Fill the radiator and sub-tank with the cooling water as followingprocedures.1) Before filling, check to be sure the drain plug is closed.2) Remove the radiator cap of the radiator by turnig theradiator cap counter-clockwise about 1/3 of a turn.3) Pour the cooling water slowly into the radiator up to thelip of the filler port so that air bubbles do not develop.4) After supplying the cooling water, surely tighten theradiator cap. To fasten the radiator cap, align the clawson the back face of the radiator cap with the notches ofthe filler port and press-turn the cap clockwise approx.1/3 of a turn until contact with each other.5) Remove the cap of the sub-tank, supply the coolingwater to the FULL mark and fasten the cap.6) Check the rubber hose connecting the sub-tank to theradiator. Be sure the rubber is securely connected andthere is no looseness or damage. When the rubberhose is not water tight, an excessive amount of coolingwater will be consumed.7) When filling with the cooling water for the first time orreplacing, the cooling water will enclose the air into thecooling water system. So, as the air in the coolingwater system is made to bleed automatically duringengine operation, the cooling water level in the radiatorand sub-tank will be lowered. Replenish the coolingwater into the radiator and sub-tank until it reaches theFULL mark of the sub-tank.OPTIONRubber hoseSub-tankCooling water capacity :FULL(Max. limit)Radiator capLOW(Min. limit)Drain plug(Drain plug location depends on the machine unit)
