If water or dust is deposits in fuel, replace the
fuel lter.

Air bleeding: The fuel system runs from the fuel
tank through the fuel filter, fuel injection pump
and high pressure piping, to the injector. Fuel
is not injected if there is air in the fuel system.
Bleed the air according to the following steps.
1) Loosen the air bleeding screw at top of the fuel
lter until foamy. And then put the clothes near
the air bleeding screw for prevent overow fuel.
2) If fuel doesn’t include bubbles, tighten the air
bleeding screw.

WARNING
2.2.4 COOLANT
The coolant must use the soft water (such as
tap water, etc). Hard water such as well water
causes scale deposits on the coolant system.
This reduces the cooling efficiency and raises
the coolant temperature too high, causing
seizures between the piston and the liner. Use
an anticorrosive for prevent rot at summer
season and use a coolant for prevent freezing at
winter season.
The anti-freezing liquid to dilute to 40~60%
based on the quantity of coolant according to
vehicle type.
•
•
Replace the coolant: Every 500hrs or every
2years.
Contaminated coolant reduces cooling efciency
so the temperature could be raised too high. This
might cause the engine seizure.
Before operating the engine, always check the
amount of coolant in the sub-tank. In addition,
check the amount of coolant in the radiator at
least once a week. If the coolant is not enough,
engine temperature will be raised high. This
could be a cause of engine seizure.
