(1) Net
(2) Wing bolts
24. CLEANING OF THE RADIATOR
(1) Radiator
(2) Radiator screen
IMPORTANT: • The radiator screen and radiator clogged
with dust or dirt causes overheating of
the engine due 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 ra-
diator screen is located behind the radiator.
a. Pull out the radiator screen upwards.
b. Dust off the radiator screen with a soft brush.
c. The clogged radiator screen 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 wir-
ing and electric apparatus.
• After washing the radiator using water
from a tap, let it dry by itself.
25. REPLACEMENT OF COOLANT
Warning: Never attempt to remove the ra-
diator 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 in-
side of the radiator and tighten the drain plug securely.
d. Pour the coolant which has a specified antifreeze con-
centration until it starts overflowing through the cool-
ant filler. Retighten the radiator cap securely.
