5.5.3 INSPECT COOLANT LEVEL REGULARLY
Heat radiator is located at the tail of the machine.
Water inlet of heat radiator, see right figure:
1. Slowly uncap the pressure cap at the upper section of the heat radiator, and gradually release the
pressure.
Under thermo-mechanical state, do not immediately open the heat radiator pressure cap, to
avoid the high-temperature coolant or steam damaging the skin, gradually open or wait until
the coolant temperature drops down to about 50
℃
and then open it.
2. Maintain the coolant in the right position (6% the expansion space need to reserved), add coolant,
if necessary.
Adding coolant when the engine is at high temperature will cause coolant boiling and damages
to the engine. Fatherly fill coolant till the coolant temperature is below 50
℃
.
3. Tighten the heat radiator pressure cap.
5.5.4 CLEANING OF COOLING SYSTEM
The machine takes 4800 hours running or two years (whichever occurs first) as a cycle, and it
requests to replace coolant and clean up the cooling system.
Prior to that, if the coolant is contaminated, and the engine is overheating, corrosion or bubble
occurred in the cooling system, it is necessary to clean the cooling system in advance and replace
coolant.
Manually switch on the negative pole switch of the battery, insert the key in starter switch and turn
with clockwise rotation to switch on the power of the whole vehicle, and turn on the warm function
of the conditioning air-system.
Turn on the water valve of the two heater of the inlet and outlet water pipe of the evaporator from
the engine to the air-conditioning system with counter-clockwise rotation.
