29. RADIATOR
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 front the engine and the radiator
net,9, is located between air intake box,11, and the
radiator.
a. Dust off the radiator screen with a soft brush.
b. The clogged radiator fins should be cleaned by
applying compressed air or water from both sides
alternatively.
c. 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.
30. 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.
The drain plug of the engine coolant is located under the
reserve tank on the left side of the engine.
a. Place a coolant receiver under the drain plug,1.
b. Remove the radiator cap,2, 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.
