■ Anti-Freeze
If cooling water freezes, it can damage the cylinders and
radiator. It is necessary, if the ambient temperature falls
below 0°C (32°F ), to remove cooling water after operating
or to add anti-freeze to it.
1. There are two types of anti-freeze available; use the
permanent type (PT) for this engine.
2. Before adding anti-freeze for the first time, clean the
radiator interior by pouring fresh water and draining it
a few times.
3. The procedure for mixing of water and anti-freeze
differs according to the make of the anti-freeze and the
ambient temperature, basically it should be referred to
SAE J1034 standard, more specifically also to SAE
J814c.
4. Mix the anti-freeze with water, and then fill the radiator.

At 760mmHg pressure (atmospheric). A higher boiling
point is obtained by using a radiator pressure cap
which permits the development of pressure within the
cooling system.
NOTE:
• The above data represents industry standards that
necessitate a minimum glycol content in the
concentrated anti-freeze.
• When the cooling water level drops due to
evaporation, add water only. In case of leakage, add
anti-freeze and water 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
contains an anti-corrosive agent, which will react with
the radiator cleaning agent forming sludge which will
affect the engine parts.)

■ Bleeding
Fuel System
Air must be removed:
1. When the fuel filter or lines are removed.
2. When tank is completely empty.
3. After t_h_e tractor has not been used for a long period of
timei:.-
♦
Bleeding procedure is as follows:
1. Fill the fuel tank with fuel.
(1) Fuel pump
(2) Fuel fuller
2. Turn the key switch to "ON" position for about 30
s~conds. Doing so allows fuel pump to work and pump
air out of the fuel system.
3. Start the engine and run for about 30 seconds, and
then stop the engine.
