22. CLEANING OF THE RADIATOR
IMPORTANT:
•
The radiator screen and radiator clogged with dust or
dirt causes overheating of the engine due to deterio-
rated cooling efficiency of the radiator.
The radiator and radiator screen should be checked
for clogging everyday before operation.
• When mowing dead grass or operating under
extremely dusty conditions, check the radiator screen
and radiator several times a day to avoid clogging.
The radiator is located behind the engine and the radi-
ator screen is located behind the radiator.
a. Draw out the radiator screen upwards.
b. Dust off the radiator screen with a soft brush.
c. The clogged radiator fins should be cleaned by apply-
ing compressed air or water from both sides alterna-
tively.
d. Re-install the radiator screen.
IMPORTANT:
•
Avoid using excessively compressed air or water,
which may deform the cooling fan blades.
• Avoid applying water directly to the wiring and electric
apparatus.
• After washing the radiator using water from a tap, let it
dry by itself.
23. COOLANT REPLACEMENT
WARNING: Never attempt to remove the radi-
ator cap during or just after operation, or
pressurized vapor and hot water will gush
out, which may cause burns. So wait until the
engine cools down sufficiently.
The drain plug of the engine coolant is located under
the reserve tank of the left side of the engine.
a. Place a coolant receiver under the drain plug.
b. Remove the radiator cap and the drain plug to let all
coolant drain out of the radiator and engine cylinder
block.
c. When all coolant completely drained out, wash the
inside of the radiator and tighten the drain plug
securely.
