This tractor is filled with 50% of eth -
ylene glycol at factory.
if the anti-freeze has been replaced
by tap water later on, the coolant can
freeze, leading to damage to the cyl-
inder and radiator when the ambient
temperature is below zero (32 °f).
therefore, make sure to change
water into anti-freeze before winter
season comes.
when changing the anti-freeze with
one of another type, flush the cooling
system several times and contact a
professional for the mixture ratio.
ANTI-fREEzE
* at 760 mmhg pressure (atmo-
spheric). a higher boiling point is
obtained by using a radiator pres-
sure cap.
the temperatures shown on the left
are industry standards that necessi-
tate a minimum glycol content in the
concentrated antifreeze.
when the coolant level drops due to
evaporation, add water only. in case
of leakage, add anti-freeze and wa-
ter in the specified mixing ratio.
anti-freeze absorbs moisture.
keep unused anti-freeze in a tightly
sealed container.
Do not use radiator cleaning agents
when anti-freeze has been added to
the cooling water. (anti-freeze con-
tains an anti-corrosive agent, which
will react with the radiator cleaning
agent forming sludge which will af-
fect the engine parts)

1. make sure that the amount of fuel
in the fuel tank is sufficient.
2. if air is introduced into the fuel
filter, unscrew the bleeding bolt
(2) shown in the above figure, and
turn the ignition switch to run the
start motor. then, air in the fuel
filter is bled through the bleeding
bolt as shown in the figure above.
