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.
• Start the engine, turn off after 5 minutes idle operation, then switch on again, slowly
turn off the pressure cap of the heat radiator to release pressure till the coolant
temperature is below 50 ℃ .
• Open the outlet valve
at
the bottom of the heat radiator, drain out the engine coolant.
Heat radiator is located at the tail of the machine.
Water inlet of heat radiator, see right figure:
