to deteriorated 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
radiator 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
applying compressed air or water from both sides
alternatively.
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.
24. COOLANT REPLACEMENT
Warning:
Never attempt to remove the radiator 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.
(1) Drain plug
The drain plug of the engine coolant is located on
the bottom 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.
d. Pour the coolant which has a specified antifreeze
concentration until it starts overflowing through
the coolant f iller. Retighten the radiator cap
securely.
Warning:
Be sure to tighten the radiator cap securely, or
boiling coolant may shoot out, which is very
dangerous.
Important:
• Frozen coolant may damage the engine.
• Mixing ratio of water and antifreeze is different by
antifreeze manufacturers and atmospherc temper-
atures.
• Water and anifreeze should be blended sufficiently
ahead of time.
e. After filling, start the engine and let it idle for 5
minutes or so. Then check the coolant level. If the
level is low, replenish the reserve tank with
coolant. (Refer to page 38.)
Important:
• Never attempt to run the engine without coolant,
or the engine will seize, leading to its complete
damage.
