23. 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
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.
