Perform the following instructions
when the coolant temperature is close
to or over the boiling point.¬ Take the
appropriate action when the warning
buzzer sounds or warning lamp is
illuminated.
1. Stop the machine in a safe place
and leave the engine unloaded.
2. Do not stop the engine right away.
Instead, run the engine without load

It is necessary to clean the engine
cooling system at every 500 hours of
operation. Also, clean it before and
after using anti-freeze.

Do not clean the radiator core
with a hard object, such as a
screwdriver. A hard object can
damage the special radiator
fins, resulting in malfunction
of the radiator.

IMPORTANT
ANTI-FREEZE
* At 760 mmHg pressure (Atmo-
spheric). A higher boiling point is
obtained by using a radiator pres-
sure cap.

If the anti-freeze has been replaced
by tap water later on, the coolant can
be frozen, leading to damage to the
cylinder and radiator when the ambi-
ent temperature is below 0℃.
Therefore, make sure to change
water into anti-freeze before winter
season comes.
When changing the anti-freeze with
