3- Mount the drain pin, add necessary anti-freezing
liquid or long life coolant, and fill with pure water.
4- Mount the cover of main radiator cap and start up the
engine to fully mix the anti-freezing liquid or long life
coolant with cooling water.

<Use of anti-freezing liquid>
Anti-freezing liquid can reduce the freezing point of
water. Before delivery, the mixing ratio of the liquid is
determined based on a cold resistance of -15℃,
namely 70% water and 30% anti-freezing liquid. This
mixing ratio should be adjusted if the ambient
temperature is below -15℃.

<Long life coolant>
It is suggested to use a long life coolant for diesel
engine instead of clean water. The long life coolant
avoids from rusting inside of the radiator.
[Precaution]
When replacing with new cooling water, be
sure to add the anti-freezing liquid or long life
coolant and perform idle running of the engine
for 5 minutes to mix the liquid as quickly as
possible.
The mixing ratio, which varies with
manufacturers, should be determined
according to the instruction manual provided
by the manufacturer.
You can fill with pure water to make up natural
consumption of cooling water.
The effective period of anti-freezing liquid is 1
year. Therefore, replace with new anti-freezing
liquid every year.
5. Replacing fuel filter
Open flame is prohibited during operation.
Be sure to wipe off fuel attached on all
parts. Otherwise, fire hazard may be
caused.
After opening the rear cover of engine, you can see the
fuel filter above the rear part of engine, a black
container connected with the fuel inlet pipe and the inlet
pipe of injection pump. (This is a one-piece filter that
can not be cleaned and should be replaced with a new
one.)
<Replacing>
1- When mounting the new filter with air inside, turn the
key switch to “ON” to exhaust air.
