When draining water from the fuel
tank, always use a container which is
suitable for the water quantity.
* Otherwise, the drained water will overflow from
the container, which may flow outside of the
facility.
* The water drained into the container is
contaminated with fuel. Discard the water in
accordance with the local laws and regulations
as well as the manufacturer's SDS.
Drain water properly from the fuel
tank.
* If water, dust, or other foreign particles are left,
they may mix with fuel and cause low output
power or damage to the devices in the fuel
system.
Bleed air sufficiently from the fuel
system.
* Otherwise, starting failure may occur.
After bleeding, tighten the priming
pump firmly.
* If the tightening torque is too weak, fuel leak
may occur.
* If the tightening torque is too strong, the priming
pump may be damaged.
When draining water from the water
separator, always use a container
which is suitable for the water
quantity.
* Otherwise, the drained water will overflow from
the container, which may flow outside of the
facility.
* The water drained into the container is
contaminated with waste oil. Discard the water
in accordance with the local laws and
regulations as well as the manufacturer's SDS.
Drain water properly from the water
separator.
* If draining the water separator is insufficient,
water may enter into the fuel system, which
causes damage to the devices.
Open the inlet valve of the water
separator slowly to prevent fuel in the
water separator from spilling out.
Wrap a cloth around the water
separator.
* Otherwise, spilled fuel may ignite and cause a
fire.
Tighten the cover and cock on the
water separator appropriately.
* Fuel leaks due to the tightening torque being
loose may cause a fire or fuel flow-out, which
results in environmental pollution.
Clean the gauze filter properly.
* A clogged gauze filter may result in insufficient
fuel supply, low power output, or engine stall
during operation.
When replacing the gauze filter,
tighten the new one under the same
condition as the old one was installed.
* Fuel leaks due to the tightening torque being
loose may cause a fire or fuel flow-out, which
results in environmental pollution.
Do not pour fuel into the fuel filter
before installing it.
* Otherwise, it may cause serious personal injury,
environmental pollution due to fuel flowing
outside of the facility, or damage to the devices.
* Follow the installation procedure described in
this Operation & Maintenance Manual.
Use a genuine fuel filter.
* If a non-genuine filter is used, deterioration in
the exhaust gas properties and damage to the
devices may occur due to insufficient air intake.
* Failures or damages caused by using non-
genuine parts will be outside the scope of the
warranty.
